[PVE-User] [pve-devel] online migration broken in latest updates - "unknown command 'mtunnel'"

[Yannis Milios]

Not sure if it's related, but after upgrading yesterday to the latest
updates, Ceph snapshots take a very long time to complete and finally they
fail.
This happens only if the VM is running and if I check the 'include RAM' box
in snapshot window. All 3 pve/ceph nodes are upgraded to the latest updates.

I have 3 pve nodes with ceph storage role on them. Below follows some more
info:
