The "cirrus" device in qemu-kvm is considered as a legacy device, which
|
|
|
ae23c9 |
also had a lot of security issues in the past. KVM guest should preferably
|
|
|
ae23c9 |
use "stdvga", "virtio-vga" or "qxl" as graphics card nowadays instead.
|
|
|
ae23c9 |
To avoid that we have to carry along the legacy "cirrus" device in
|
|
|
ae23c9 |
downstream qemu-kvm forever, let's mark it as deprecated in RHEL8 now,
|
|
|
ae23c9 |
so that we can finally remove it in RHEL9.
