[one-users] Host with different TM - migration

[Grzegorz Kocur]

Hi,

Scenario:
Host A - uses tm_ssh, id 1
Host B - uses tm_shared, id 2
VM running on host A

onevm migrate <vmid> 2
and I have error:

IMO the problem is migration uses host B TM (shared), and doesn't scp 
disk image and checkpoint to host B.
Is it a bug? Any workaround?
