Oracle VM Manager upgrade improvements significantly reduces upgrade time. For upgrade instructions, see Upgrading Oracle VM Manager in the Oracle VM Installation and Upgrade Guide.

IP addresses entered in Oracle VM Manager are always validated to ensure correct formatting. An error message is displayed if the IP address is not properly formatted.

The Linux kernel device manager (udev) has been improved to increase performance. The most significant improvement is that the time udev takes to run after booting the server has been shortened from 2-3 minutes to just seconds, eliminating system 'hangs' and other problems in systems which are sensitive to startup time.

When the management network also fulfills the role of virtual machine network, a bridge for virtual machine network connectivity is created on Oracle VM Servers as they are added to the environment. As a result, virtual machines will continue to work properly when migrated to a new Oracle VM Server.

DHCP is able to be used for VLAN Group interfaces.

Both Oracle VM Server and the Unbreakable Enterprise Kernel (UEK) have been patched to prevent the flood of kernel warning messages caused by illegal configuration of certain Broadcom NetXtreme II XGb (bnx2x) network controllers. If an illegal configuration is detected, only one warning message per controller card is displayed.

Several network throughput issues with certain Broadcom NetXtreme II XGb (bnx2x) network controllers on Oracle VM Server have been resolved: default TPA settings have no adverse effect on network throughput, and network between virtual machines and NFS storage no longer hangs with bnx2x controllers.

When using the untagged VLAN segment, the user must configure IP address information on the NIC port, not on the VLAN interface. This eliminates duplicate configurations and any associated risks of misconfiguration.

A late locking scheme has been implemented for networks on virtual machine clones: the virtual NIC connection in the virtual machine is only locked at the end of the clone operation. As a result, locking issues with ethernet networks no longer occur when multiple virtual machines are cloned in parallel from the same template.

In Oracle VM Manager, the Acknowledge All Events button effectively clears all events, not just the items visible in the current list view.
