[Users] VM migrations failing

[Dead Horse]

To test further I loaded up two more identical servers with EL 6.3 and the
same package versions originally indicated. The difference here is that I
did not turn these into ovirt nodes. EG: installing VDSM.

- All configurations were left at defaults on both servers
- iptables and selinux disabled on both servers
- verified full connectivty between both servers
- setup ssh (/root/authorized keys) between the servers --> this turned out
to be the key!

Then using syntax found here:
http://libvirt.org/migration.html#flowpeer2peer
EG: From the source server I issued the following:

virsh migrate --p2p sl63 qemu+ssh://192.168.1.2/system

It fails in exactly the same way as previously indicated when the
destination server does not have an ssh rsa pub ID from the source system
in it's /root/.ssh/authorized_keys file.
However once the ssh rsa pub ID is in place on the destination system all
is well and migrations work as expected.

Next I tried the same on the identical servers acting as ovirt nodes. (EG:
installed with and running VDSM) The above did not do the trick, still
fails the same exact way. Thus this leads me to believe something with VDSM
or a configuration alteration made by it is to blame.

I should note that I have SSL=disabled on my engine/nodes
EG: vdc_options --> SSLEnabled = false, UseSecureConnectionWithServers =
false, EnableSpiceRootCertificateValidation = false

vdsm.conf (same on both nodes):
[addresses]
management_port = 54321

[vars]
ssl = false

libvirtd.conf alterations by VDSM (same on both nodes excluding host_uuid)
