Hello Christian, or anyone else affected,
Accepted libvirt into disco-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/libvirt/5.0.0-1ubuntu2.2 in a few
hours, and then in the -proposed repository.
Please help us by testing this new package. See
Now that it is complete in Eoan and upstream accepted I uploaded it to
Disco-unapproved as well.

There are conditions where old qemu/libvirt created guests with the
osxsafe or ospke cpu feature:
That feature was removed in recent qemu, this triggers issues starting
some old guests definitions using it after upgrade.

Some details from testing that make it even less severe ...
Note: since this was never in any Host defined any required setting would have
triggered a pre-check like:
error: the CPU is incompatible with host CPU: Host CPU does not provide
required features: ospke
But if set to optional:
I have created a preliminary patch and a PPA for Disco with it.
The plan is to do some testing on that and then suggest the change upstream.
History has shown that such fixes can differ greatly depending on the
"preferred style" how to implement it thou - so there might be a few iterations
The fix in newer virt-install might be related to https://github.com

Triggers that would in the past have added the flag in the past - it
will have to be fixed anyway, but this is mostly to evaluate the
severity/urgency of the issue.
TL;DR: it seems rare to have been added, yet we haven't covered all
cases and there must be a reason why it occurred
