Hello Forum,
since the upgrade to qemu 2.11 (i think the issue is here, i cant say for sure, but it came with the last "monthly update" i did) i get a strange error while performing livemirgration.
At first a migrations works but still output this error:
The VM is mirgrated after that and it seems to work "perfectly"
However, when i try to migrate back to the same node the vm was running before:
I tried to execute the command that failed and got:
Do you guys have any idea or can confirm?
Kind regards
