I'm thinking to upgrade the libvirt to solve the problem as you said in your last mail.
But I've installed the package using "apt-get install" and I can''t get higher version of all the packages involves doing an upgrade in ubuntu (I'm using 10.04)
Can you suggest-me "an easy" way to upgrate the libvirt?
Thank you very much.

which is usually a symptom associated with SELinux permissions. But you
said earlier in this thread that you aren't using SELinux. Are you
using AppArmor?
At any rate, does upgrading to libvirt 0.9.0 improve the situation?
exec: migration has always been risky (there are various data races
involved in coordinating multiple processes, where qemu is using popen()
to manage the use or even opening the file), and so newer libvirt uses
fd: migration (where the fd is already open, so we don't even have to
worry about permissions from qemu's point of view).
