Several other user space packages were also updated to align with the latest Oracle Linux 6 Update 9 versions, or to resolve dependencies.

Performance and Scalability

Increased Performance for Microsoft Windows guest operating systems

This release provides the ability to enable the exposure of Windows virtualization (also referred to as viridian) compatible entitlements to Microsoft Windows guest operating systems. Enabling viridian support is strongly recommended to ensure improved performance for all Microsoft Windows guest operating systems. For more information about how to enable this support, see Create Virtual Machine in the Oracle VM Manager User's Guide.

Hybrid Columnar Compression Support

As of this release, Oracle VM provides support for Hybrid Columnar Compression (HCC) on Oracle Database Release 18c with Oracle ZFS Storage Appliance and Oracle FS1 Series Flash Storage Systems. Hybrid Columnar Compression is an Oracle Database compression technology that enables the highest levels of data compression and provides cost savings and performance improvements due to reduced I/O.

Note

The following RPM packages are required for Oracle VM to provide support for Hybrid Columnar Compression (HCC) on Oracle Database Release 18c:

  • The ovmport-1.0-8.el6.x86_64.rpm package must be installed on the Oracle VM Server instance. This package is included by default with the Oracle VM Server Release 3.4.5 ISO.

  • The libxenstore and libxenstore-devel packages must be installed on the Oracle Linux 6 or 7 guest. These packages are available from the addons channel for the Oracle Linux Yum Server.

For more information, see the Hybrid Columnar Compression section of the Oracle Database Concepts guide for Oracle Database Release 18c.

Usability

Additional VM Migration Check Added to Oracle VM Manager Stop and Restart Options

A check_migrate option is now available for use with the Oracle VM Manager stop and restart commands, allowing you to check for active VM migration jobs that are triggered by a server pool load balancing job. For more information, see Starting and Stopping Oracle VM Manager in the Oracle VM Installation and Upgrade Guide.

New Start Policy Available for Virtual Machines

A new virtual machine start policy called Balance Server is now available for selection when creating or editing a server pool or virtual machine. Virtual machines can be started on the best available Oracle VM Server as determined by CPU and memory utilizations, with CPU utilization taking precedence over memory utilization. This ensures that virtual machines are evenly distributed amongst all Oracle VM Servers in the server pool, starting with the least utilized Oracle VM Server first. For more information, see Servers and VMs Tab in the Oracle VM Manager User's Guide.

New LIP Scan Option for Fibre Channel Storage Arrays

A Loop Initialization Protocol (LIP) scan is now optional and can be enabled when modifying an Unmanaged FibreChannel Storage Array. A LIP issued to an Oracle VM Server connected to a fabric causes the Host Bus Adapter (HBA) driver to reset the SCSI bus and as a result, may also cause the target to reset. Disabling a LIP scan for an Unmanaged FibreChannel Storage Array may result in faster times for storage array refreshes when configuring a new SCSI target on a Fibre Channel interconnect. For more information, see the Storage Tab section in the Oracle VM Manager User's Guide and the CLI Command Reference section in the Oracle VM Manager Command Line Interface User's Guide .

Server Upgrade Warning Events Displayed with Blue Icon

After an Oracle VM Manager upgrade, there are warning events associated with each Oracle VM Server that has not yet been upgraded to the latest version. Oracle recommends that you upgrade to the latest version of Oracle VM Server at your earliest convenience, but it is not a strict requirement. Previously, both warnings and errors were displayed in the Events perspective of the Oracle VM Manager Web Interface with the same red icon, although in practice there is a clear difference in severity level and priority. As of this release, the warning events for Oracle VM Servers requiring upgrade are displayed with a blue icon, to make them visually distinguishable.

Documentation

New Section Listing Oracle VM Release 3.4 Deprecated Features

As of Oracle VM Release 3.4.5, a new section called Chapter 8, Deprecated and Removed Oracle VM Features has been added to the Oracle VM Release Notes. This can be used to track features that have been deprecated and removed for current and previous Oracle VM Release 3.4.x release.

Security

Support for TLS Version 1.2 Protocol

As of this release, Oracle VM Manager uses the TLSv1.2 protocol for all connections to ensure enhanced security protection. As a result, management of Oracle VM Server for x86 at Release 3.2.10 or 3.2.11, and Oracle VM Agent for SPARC at Release 3.3.1, is not possible by default. It is strongly recommended to upgrade your Oracle VM Server instances to the latest version, but if this is not possible, you can enable the TLSv1 protocol, which is less secure. For instructions, see Enabling the TLS Version 1 Protocol in the Oracle VM 3.4 Installation and Upgrade guide.

Xen 4.4.x Performance and Scalability Updates

  • Idle Driver Updates: The mwait idle driver has been improved to make use of deeper C-states on Broadwell and Skylake platforms. In addition, turbo boost works properly when C-states are in use.

  • Better ACPI Handling: ACPI handling has been improved to enable turbo boost functionality on Oracle Server X7 based platforms.

  • Improved Memory Scrubbing: The scrubbing mechanism allows better handling of memory assigned to a domain close to the host boundaries. This prevents out-of-memory issues when guest-driven reboots occur.

  • APICv Support: On platforms that support it, APICv is exposed, allowing guests to use native MSI-X handling for PCI devices, instead of pirqs. This results in a latency improvement of approximately 10 percent for certain workloads.

3.7 What's New in Oracle VM Release 3.4.3?

The new features and enhancements in Oracle VM Release 3.4.3 include:

Installation and Upgrades

Simplified UEFI PXE Boot for Oracle VM Server

As of this release, you do not need to manually build the GRUB 2 boot loader to install Oracle VM Server on UEFI-based systems in a PXE boot environment. The Oracle VM Server ISO image file provides the /EFI/BOOT/grubx64.efi boot loader for UEFI-based systems. See Installing Oracle VM Server for x86 from PXE Boot in the Oracle VM Installation and Upgrade Guide.

Note

If you plan to install Oracle VM Server on BIOS-based systems, you use the pxelinux.0 boot loader from the syslinux package on Oracle Linux.

Infrastructure

Support for Software RAID Devices with Oracle VM Server

You can now create kickstart configurations that assemble software RAID devices during the Oracle VM Server installation. See Software RAID Partitions in the Oracle VM Installation and Upgrade Guide.

You can also create software RAID devices in dom0 after installation. Oracle VM Server then presents those software RAID devices to Oracle VM Manager so that you can use them as storage repositories or for virtual disks. See Configuring Software RAID for Storage in the Oracle VM Administrator's Guide.

Important

The following notes apply to using software RAID devices with Oracle VM Server in this release:

  • Oracle VM Server supports installation on software RAID devices on BIOS-based systems only.

  • You should not attempt to install Oracle VM Server on a software RAID if a disk that is 2 TB or larger is a member of the array. Due to a limitation with the Master Boot Record (MBR), Oracle VM Server cannot boot from disks that are 2 TB or larger in a software RAID configuration.

  • As a best practice, you should use software RAID devices as storage repositories in a test environment before using them in a production environment.

  • In environments where you use software RAID devices as storage repositories for server pools, unexpected behavior can occur with certain virtual machine migration operations. For example, if you clone a virtual machine and then attempt to live migrate it to an instance of Oracle VM Server in the same server pool, the migration fails with an error that indicates the virtual machine disk does not exist. In this case, you must stop the virtual machine and then move it to the appropriate instance of Oracle VM Server.

Support for Microsoft Windows Server Failover Clustering

Microsoft Windows Server guests can now use SCSI-3 persistent reservation to form a Windows Server Failover Cluster (WSFC) with Oracle VM Paravirtual Drivers for Microsoft Windows Release 3.4.2 or later. See Oracle VM Paravirtual Drivers for Microsoft Windows for information about failover cluster capabilities on specific Microsoft Operating System versions.

Update to Oracle VM Agent for SPARC

As of this release, Oracle VM Agent for SPARC is updated to run Python 2.7.

Update to the dom0 Kernel

The dom0 kernel is updated to a newer Unbreakable Enterprise Kernel Release 4 (UEK R4) version kernel-uek-4.1.12-61.40.1.el6uek.x86_64.rpm.

Note

This UEK R4 kernel update is a quarterly update 2 (QU2) errata version.

If you received a one-off version of UEK R4 QU2 before this release, you should upgrade Oracle VM Server to UEK R4 QU4 after you upgrade to Oracle VM Release 3.4.3. Upgrading the kernel ensures your Oracle VM Servers include any bug fixes that were included in the one-off version of UEK R4 QU2.

If you are upgrading from an earlier release of Oracle VM, such as Release 3.4.2, and you have a mainstream version of UEK R4, you can optionally upgrade Oracle VM Server to UEK R4 QU4 after you upgrade to Oracle VM Release 3.4.3.

The UEK R4 QU4 version of the kernel is available on the Oracle Linux Yum Server for all Oracle VM Release 3.4.3 users.

Package Additions and Updates

The full list of package additions and updates is beyond the scope of this document, but the following list includes the notable package updates that are included in this release:

  • The tzdata package is updated to tzdata-2017b-1.el6.noarch.rpm.

  • The Netscape Portable Runtime (NSPR) package is updated to nspr-4.11.0-1.el6.x86_64.rpm.

  • The ovmport package is updated to ovmport-1.0-6.el6.x86_64.rpm.

Updates to Multipath Configuration for Oracle ZFS Storage Appliance

  • This release includes the Oracle Sun ZFS Storage.* product in the multipath.conf file, which includes the ZFS Storage 7350 and ZFS Storage 7330 products.

  • The default value for the multipath configuration parameter no_path_retry is updated to 180. This new default setting enhances the performance of the multipath daemon, multipathd, and improves response times when issuing the multipath -ll command.

Performance and Scalability

3.8 What's New in Oracle VM Release 3.4.2?

The new features and enhancements in Oracle VM Release 3.4.2 include:

Installation and Upgrades

Oracle VM Manager support for previous Oracle VM Server releases

As of Oracle VM Release 3.4.2, Oracle VM Manager supports current and previous Oracle VM Server releases. For more information, see Chapter 6, Oracle VM Manager Support for Previous Oracle VM Server Releases.

Infrastructure

Support for NVM Express (NVMe) devices

Oracle VM Server now discovers NVMe devices and presents them to Oracle VM Manager, where the NVMe device is available as a local disk that you can use to store virtual machine disks or create storage repositories.

The following rules apply to NVMe devices:

Oracle VM Server for x86

  • To use the entire NVMe device as a storage repository or for a single virtual machine physical disk, you should not partition the NVMe device.

  • To provision the NVMe device into multiple physical disks, you should partition it on the Oracle VM Server where the device is installed. If an NVMe device is partitioned then Oracle VM Manager displays each partition as a physical disk, not the entire device.

    You must partition the NVMe device outside of the Oracle VM environment. Oracle VM Manager does not provide any facility for partitioning NVMe devices.

  • NVMe devices can be discovered if no partitions exist on the device.

  • If Oracle VM Server is installed on an NVMe device, then Oracle VM Server does not discover any other partitions on that NVMe device.

Oracle VM Server for SPARC

  • Oracle VM Manager does not display individual partitions on an NVMe device but only a single device.

    Oracle recommends that you create a storage repository on the NVMe device if you are using Oracle VM Server for SPARC. You can then create as many virtual disks as required in the storage repository. However, if you plan to create logical storage volumes for virtual machine disks, you must manually create ZFS volumes on the NVMe device. See Creating ZFS Volumes on NVMe Devices in the Oracle VM Administrator's Guide.

Using Oracle Ksplice to update the dom0 kernel

Oracle Ksplice capabilities are now available that allow you to update the dom0 kernel for Oracle VM Server without requiring a reboot. Your systems remain up to date with their OS vulnerability patches and downtime is minimized. A Ksplice update takes effect immediately when it is applied. It is not an on-disk change that only takes effect after a subsequent reboot.

Note

This does not impact the underlying Xen hypervisor.

Depending on your level of support, contact your Oracle support representative for assistance before using Oracle Ksplice to update the dom0 kernel for Oracle VM Server. For more information, see Oracle VM: Using Ksplice Uptrack Document ID 2115501.1, on My Oracle Support at: https://support.oracle.com/oip/faces/secure/km/DocumentDisplay.jspx?id=2115501.1.

Extended SCSI functionality available for virtual machines

Oracle VM now provides additional support for SCSI functionality to virtual machines:

  • Linux guests can now retrieve vital product data (VPD) page 0x84 information from physical disks if the device itself makes it available.

  • Microsoft Windows Server guests can use SCSI-3 persistent reservation to form a Microsoft Failover Cluster in an upcoming Oracle VM Paravirtual Drivers for Microsoft Windows release. See the Oracle VM Paravirtual Drivers for Microsoft Windows documentation for information about the availability of failover cluster capabilities on specific Microsoft Operating System versions.

Dom0 kernel upgraded

The dom0 kernel for Oracle VM Server is updated to Oracle Unbreakable Enterprise Kernel Release 4 Quarterly Update 2 in this release.

Package additions and updates

  • The ovmport-1.0-1.el6.4.src.rpm package is added to the Oracle VM Server ISO to support Microsoft Clustering and enable communication between Dom0 and DomU processes using the libxenstore API.

  • The Perl package is updated to perl-5.10.1-141.el6_7.1.src.rpm.

  • The Netscape Portable Runtime (NSPR) package is updated to nspr-4.11.0-1.el6.x86_64.rpm.

  • The openSCAP package is updated to openscap-1.2.8-2.0.1.el6.rpm.

  • The Linux-firmware package is updated to linux-firmware-20160616-44.git43e96a1e.0.12.el6.src.rpm.

Performance and Scalability

Oracle VM Manager performance enhancements

This release enhances the performance of Oracle VM Manager by reducing the number of non-critical events that Oracle VM Server sends to Oracle VM Manager when a system goes down.

Note

If you are running a large Oracle VM environment, it is recommended to increase the amount of memory allocated to the Oracle WebLogic Server. This ensures that adequate memory is available when required. See Increasing the Memory Allocated to Oracle WebLogic Server in the Oracle VM Administrator's Guide for more information.

Oracle VM Server for x86 performance optimization

For information on performance optimization goals and techniques for Oracle VM Server for x86, see Optimizing Oracle VM Server for x86 Performance, on Oracle Technology Network at: http://www.oracle.com/technetwork/server-storage/vm/ovm-performance-2995164.pdf.

Xen 4.4.4 performance and scalability updates

  • Improved memory allocation: Host system performance is improved by releasing memory more efficiently when tearing down domains, for example, migrating a virtual machine from one Oracle VM Server to another or deleting a virtual machine. This ensures that the host system can manage other guest systems more effectively without experiencing issues with performance.

  • Improved aggregate performance: Oracle VM Server now uses ticket locks for spinlocks, which improves aggregate performance on large scale machines with more than four sockets.

  • Improved performance for Windows and Solaris guests: Microsoft Windows and Oracle Solaris guests with the HVM or PVHVM domain type can now specify local APIC vectors to use as upcall notifications for specific vCPUs. As a result, the guests can more efficiently bind event channels to vCPUs.

  • Improved workload performance: Changes to the Linux scheduler ensure that workload performance is optimized in this release.

  • Improved grant locking: Xen-netback multi-queue improvements take advantage of the grant locking enhancements that are now available in Oracle VM Server Release 3.4.2.

  • Guest disk I/O performance improvements: Block scalability is improved through the implementation of the Xen block multi-queue layer.

Usability

Oracle VM Manager Rule for Live Migration

To prevent failure of live migration, and subsequent issues with the virtual machine environment, a rule has been added to Oracle VM Manager, as follows:

Oracle VM Manager does not allow you to perform a live migration of a virtual machine to or from any instance of Oracle VM Server with a Xen release earlier than xen-4.3.0-55.el6.22.18. This rule applies to any guest OS.

Table 3.1 Live Migration Paths between Oracle VM Server Releases using Oracle VM Manager Release 3.4.2

For example, as a result of this live migration rule, all virtual machines in an Oracle VM server pool running Oracle VM Server Release 3.3.2 with Xen version xen-4.3.0-55.el6.22.9.x86_64 must be stopped before migrating to Oracle VM Server Release 3.4.2.

Tip

Run the following command on Oracle VM Server to find the Xen version:

# rpm -qa | grep "xen"  

PVHVM hot memory modification

As of this release, it is possible to modify the memory allocated to running PVHVM guests without a reboot. Additionally, Oracle VM Manager now allows you to set the allocated memory to a value that is different to the maximum memory available.

Note
  • Hot memory modification is supported on x86-based PVHVM guests running on Linux OS and guests running on Oracle VM Server for SPARC. For x86-based PVHVM guests running on Oracle Solaris OS, you cannot change the memory if the virtual machine is running.

  • See the Oracle VM Paravirtual Drivers for Microsoft Windows documentation for information about the availability of hot memory modification on PVHVM guests that are running a Microsoft Windows OS. You must use a Windows PV Driver that supports hot memory modification or you must stop the guest before you modify the memory.

  • Oracle VM supports hot memory modification through Oracle VM Manager only. If you have manually created unsupported configurations, such as device passthrough, hot memory modification is not supported.

Infrastructure

Support for Oracle VM Virtual Appliances

Oracle VM Manager now provides the ability to import and export Oracle VM Virtual Appliances as a single .ova (Open Virtualization Format Archive) file or a set of .ovf (Open Virtualization Format) and .img (disk image) files. See How are Virtual Appliances Managed? in the Oracle VM Concepts Guide for more information on virtual appliances.

Note

In previous releases of Oracle VM, Oracle VM Virtual Appliances were referred to as assemblies.

Automated installation of VNC and Serial Console software

The Oracle VM Manager installer also manages the installation and upgrading of the VNC and Serial Console software package on the Oracle VM Manager host. Reducing administrative overhead during a deployment of the environment.

Storage live migration

You can now perform live migrations of running virtual machines that have virtual disks on local storage. Oracle VM uses features built into the OCFS2 file system on x86 platforms to provide this live migration capability that helps you achieve nearly uninterrupted uptime for virtual machines.

Some restrictions apply to storage live migration. In particular, there are various requirements surrounding disk space on the source and target repositories. See How Can a Virtual Machine be Moved or Migrated? in the Oracle VM Concepts Guide for more information.

Additionally, performing storage live migration can disrupt the cluster heartbeat function if the server pool file system is not separate to the cluster heartbeat file system. Additionally, you should ensure that you configure separate channels for live migration network traffic and other network functions such as cluster heartbeat. For more information about storage configuration guidelines, see Are there Guidelines for Configuring Storage? in the Oracle VM Concepts Guide. For more information about network channels, see How are Network Functions Separated in Oracle VM? in the Oracle VM Concepts Guide.

User interface enhancements for virtual disk allocation

As of this release, when editing virtual disks, Oracle VM Manager now displays the allocation type that was specified when the virtual disk was created. Additionally, tooltips are available in the Oracle VM Manager Web Interface to provide more information about how virtual disks are created and how subsequent virtual disk space is allocated. See Create Virtual Machine in the Oracle VM Manager User's Guide for more information on creating virtual machines and virtual disk allocation.

Fiber Channel over Ethernet (FCoE) support

Oracle VM provides support for installing Oracle VM Server into FCoE Storage Area Networks (SAN) over some Host Bus Adapters (HBA) or Converged Network Adapters (CNA). See Installing Oracle VM Server to Multipath Storage in the Oracle VM Installation and Upgrade Guide for more information.

Booting from UEFI

Oracle VM Server can now boot from systems that use Unified Extensible Firmware Interface (UEFI). See Installing Oracle VM Server From a DVD-ROM in the Oracle VM Installation and Upgrade Guide for more information about installing Oracle VM Server in UEFI mode.

You can install Oracle VM Server in legacy BIOS mode or UEFI mode. However, you cannot change modes after installation. For example, if you install Oracle VM Server in legacy BIOS mode, you cannot then switch to UEFI mode. If you want to change from legacy BIOS mode to UEFI mode, or from UEFI mode to legacy BIOS mode, you must re-install Oracle VM Server.

The following restrictions currently apply to UEFI mode:

  • You cannot create custom partition layouts if you are installing Oracle VM Server in UEFI mode.

  • You cannot boot Oracle VM Server from FCoE or iSCSI if you use UEFI mode.

SOAP API deprecated

The Oracle VM SOAP API is deprecated as of Release 3.4.1.

Oracle VM Utilities use Oracle VM Web Services API

The Oracle VM Utilities version 2.1 now communicate directly with Oracle VM Manager using a Oracle VM API. This change improves performance and usability of the Oracle VM Utilities. Additionally, in this release, a number of the Oracle VM Utilities scripts have been deprecated by the Oracle VM Manager Command Line Interface. For more information, see Using the Oracle VM Utilities in the Oracle VM Administrator's Guide.

P2V utility on Oracle VM Server ISO file
