[pve-devel] Dedicated Migration Network #1177 v2

[Phil Kauffman]

I have done some light testing of this and it doesn't seem to work quite 
right yet.

Things I have done.
- dist-upgrade on both machines and reboot.
- able to ssh to and from both machines on alternate network without a 
password
- Migration works when VM is off or one does not set 'type=secure|insecure'


### Migration hangs:

root at bravo-vmnode2:~# cat /etc/pve/datacenter.cfg
migration: type=secure,network=192.168.2.0/24

Nov 16 13:36:08 use dedicated network address for sending migration

This will hang until you stop it.
