[one-users] problem when migrating ubuntu

[Shankhadeep Shome]

I have done a lot of migrations with VMs on Ubuntu, first give some
information about your source and destination, your storage back end,
architecture type, the source and destination host versions etc. Are you
running the same version of kvm,xen,libvirt on both sides? Post as much as
you can about the source and sink.
