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:
Jan 03 21:26:17 starting migration of VM 100 to node 'esx1' (10.0.0.1)
Jan 03 21:26:17 copying disk images
Jan 03 21:26:17 starting VM 100 on remote node 'esx1'
Jan 03 21:26:23 starting online/live migration on tcp:10.0.0.1:60000
Jan 03 21:26:23 migrate_set_speed: 8589934592
