I still do not have a solution.
Changing the CPU model in the vm details is mostly "to be applied on next boot",
but I am not in a position to boot (I need to unpause).
If anyone understands what model to set, or how else to get past this issue
then please offer your wisdom.
As an aside, what lead to this problem in the first place? The same problem
when booting my last f30 kernel
so it must be (?) some libvirt change.
I hope that as a last resort I will be able to cold boot the vm, linux is
rather good with crash recovery.
Last resort.
TIA

Following an upgrade of the host (38->40) I could not start the vm.
The VM was running f40 for a while just fine. It was "virsh save"d a few days
ago.
$ sudo virsh save e4 /data1/VMs/libvirt/images/e4.saved
Normally I actually stop it but forgot to do it this time.
$ sudo virsh restore '/data1/VMs/libvirt/images/e4.saved'

Then, trying to resume from the UI gets the message:

Looking at the VM details I see:

What is the correct way to resume this image?
