[PVE-User] Problem with Centos 5.X virtio ethernet drivers and last PVE updates

i see that my centos 5.11 VM should have support for virtio (see below)
and according to https://access.redhat.com/articles/2488201 rhel/centos
supports this since 5.3.

so if virtio worked before a proxmox update,  then i would call this a
regression.

can you tell which proxmox version worked for you with virtio ?

i tested centos 5.11 installer on my older pve 6.0-4 (5.0.15-1-pve
kernel) , but it does not find virtual disks.
