seem that the target vm is crashing after end of the migration.

I don't known if it's possible to catch qemu crash log on target node with
#journalctl -u <vmid>.scope

Objet: [pve-devel] Fatal bug in migration

Hi all, 

Previous enterprise and the version released yesterday have a fatal bug 
which affects VM's using storage zfs_over_iscsi. Bug means that every 
VM online migrated will crash on the new node!!! The bug was introduced 
with the new way of doing migration. 

Every migration shows this:
