VM went into ERROR state after compute node reboot

Issue

• One out of two VMs on SRIOV network with Intel 25G NICs went into ERROR state after the compute node was rebooted as part of CVIM update:

- Seeing below error for that VM in nova logs:

nova/nova-compute.log:51205:2022-04-20 21:40:27.479 9 ERROR nova.virt.libvirt.driver [req-d5f2d5a5-fac4-4fce-bccf-10b476109584 - - - - -] [instance: 609ecc91-f740-41e2-885c-ad1a47eb5628] Failed to start libvirt guest: libvirt.libvirtError: internal error: process exited while connecting to monitor: 2022-04-21T04:40:27.114214Z qemu-kvm: -device cirrus-vga,id=video0,bus=pci.0,addr=0x2: warning: 'cirrus-vga' is deprecated, please use a different VGA card instead

- Saw a RedHat solution for similar [issue](https://access.redhat.com/solutions/5253171) but the VM is not even getting listed as part of virsh list in that compute node. 

- We also see the following message in the libvirt logs:

"qemu-kvm: -device vfio-pci,host=0000:d8:02.5,id=hostdev0,bus=pci.0,addr=0x4: vfio 0000:d8:02.5: failed to get group 88 status: No such device or address"
