Sources and destinations are both ubuntu 10.04.3 LTS server and ubuntu
10.04.4 LTS server up-to-date. I am using kvm on both source and
destination and libvirt. The details are:
$ virsh version
Compiled against library: libvir 0.9.11
Using library: libvir 0.9.11
Using API: QEMU 0.9.11
Running hypervisor: QEMU 1.0.0
The VMs are stored into their local filesystem, that is why I am doing
offline migration.
When I was using the stock libvir and qemu-kvm (from the ubuntu
repositories) the offline migration was always failing. Even by hand
(using virsh commands and copying the files by hand).
Once updated libvir and qemu-kvm, offline migration fails 30-40% of
times (estimated).
Sources and destinations are Intel, biprocessors, quadcore.

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.

I don't really know what could be happening with those machines. If
this problem only happens on > 10.04 VMs then it looks like a change
in the distribution that makes the VM behave like that. I would also
try stop/resume (that does the same steps as migration) and check if
the same problem arises. You can also do the stop/resume test with the
scheduler stopped and use onevm deploy to schedule the VM to the same
host, this way we can check if the problem is related to some
configuration changes between physical nodes.
