Hello 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. Marcela
