Hi all,

For a few days now we have failures in CI of the he-basic suite.

At one point the failure seemed to have been around
networking/routing/firewalling, but later it changed, and now the
deploy process fails while trying to first start the engine vm after
it's copied to the shared storage.

I ran locally OST he-basic with current ost-images, reproduced the
issue, and managed to "fix" it by enabling
ovirt-master-centos-stream-advanced-virtualization-testing and
downgrading qemu-kvm-* from 6.1.0 (from AppStream) to
15:6.0.0-33.el8s.

Is this a known issue?

How do we handle? Perhaps we should conflict with it somewhere until
we find and fix the root cause.

Please note that the flow is:

1. Create a local VM from the appliance image
2. Do stuff on this machine
3. Shut it down
4. Copy its disk to shared storage
5. Start the machine from the shared storage

And that (1.) did work with 6.1.0, and also (5.) did work with 6.0.0
(so the copying (using qemu-img) did work well) and the difference is
elsewhere.

Following is the diff between the qemu commands of (1.) and (5.) (as
found in the respective logs). Any clue?
