[one-users] Vm migration

[Rangababu Chakravarthula]

I see it did not come thru to the mailing list as text.
I am sending it again with additional information.

Do we have to modify libvirtd.conf and libvirt-bin as given here?
http://www.opennebula.org/documentation:archives:rel1.2:kvmg

Also, according to this URL
http://www.linux-kvm.org/page/Migration

vm should be started with

-incoming tcp:0:4444

I dont see that for the VM's we started using opennebula.
Here is the log from /var/log/libvirt/qemu/one-<vmid>.log

LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
/usr/bin/kvm -S -M pc-0.11 -m 256 -smp 1 -name one-522 -uuid
