i just upgrade a pve cluster to pve 4.2 (enterprise repo), but i
have the problem that i cannot do any online migrations since the

pve versions (this node has alerady rebooted after the upgrade):

(yes, i should cleanup old kernel versions...)

steps i took sofar:
* migrated all vm's of one node
* upgraded this node
* rebooted it
* tried to migrate vms back to this host to upgrade another one

since there was a thread on the mailling list about migration
problems that where fixed with newer qemu-server/pve-qemu-kvm
version, i then upgraded the other two nodes (disabeling HA first).

i still cannot online migrate, even a vm that has been booted on the
fully upgraded node.

unfortunatly the error message i get is not really informative:
ERROR: online migration failure - aborting

am i running into some known problem here or is this a new issue?



ps: rebooting the remaining nodes without migrating the VMs off them
would be really inconvinient...
