Virtualization
The following virtualization related features and functionalities are deprecated in Oracle Linux 8.
virsh iface-* Commands
virsh iface-* commands such as virsh iface-start,
virsh iface-destroy, and so on are deprecated. To configure and
manage host network connections, use instead the NetworkManager tool and its related
management applications, for example nmcli.
virt-manager Application Deprecated
The Virtual Machine Manager application (virt-manager) is deprecated in this release. To manage virtualization, use the Cockpit web console instead.
Virtual Machine Snapshots
Support for creating snapshots of VMs is limited only to those that don't use UEFI firmware. However, the operation might cause the QEMU monitor to become blocked and affects hypervisor operations.
As an alternative, use external snapshots.
Cirrus VGA Virtual GPU Type
The Cirrus VGA GPU device is deprecated and support for it might be removed in KVM
virtual machines. In its place, use stdvga,
virtio-vga, or qxi devices.
Signatures Using SHA-1
The use of SHA1-based signatures to perform SecureBoot image verification on UEFI (PE/COFF) executable files is deprecated. Instead, use signatures that are based on SHA-2 or later.
SPICE Remote Display Protocol
With the deprecation of the SPICE remote display protocol, the functionality of attaching smart card readers to virtual machines (VMs) will be provided by third party remote virtualization solutions.
Also, the deprecation of this protocol has the following consequences:
- For remote console access, use the VNC protocol.
- For advanced remote display functions, use third-party tools such as RDP, HP RGS, or Mechdyne TGX.
