alpine-container-disk-demo VM image's kernel not compatible with latest AMD Zen3 microarchitecture node

[pbxqdown]

What happened:
When trying to run alpine-container-disk-demo VM on a AMD Zen3 node with INVPCID feature, the VM has kernel panic during startup.
The VM's kernel log is as follows:

Cause of the issue:
The old kernel in the VM is not handling the new Zen3 INVPCID feature.
The kernel version is 4.9.65-1 and is missing this patch: https://www.spinics.net/lists/stable/msg453918.html

Environment:

• KubeVirt version (use virtctl version): N/A
• Kubernetes version (use kubectl version): N/A
• VM or VMI specifications: N/A
• Cloud provider or hardware configuration: N/A
• OS (e.g. from /etc/os-release): N/A
• Kernel (e.g. uname -a): 4.18.0-348.20.1.el8.1653519607.fda72e83b1.x86_64(host node)
• Install tools: N/A
• Others: N/A

@pbxqdown hey, the containerdisk-demo images are not coming from this repo (they are part of kubevirt/kubevirt). Also note that kubevirt stopped using floating tags a long time ago, so the latest image is probably super-old. You could probably use the v0.57.0 tag or something like that ,but as said they are just for kubevirt/kubevirt development.

You can checkout supported images here: https://quay.io/organization/containerdisks/

Thanks for the clarification. I found that latest image is used a lot in the test. maybe it is because 0.50 version is not up-to-date.
