Hi,
Some news...... rolled back the machine to Xen 3.3.1,
problem disappear, maybe the 3.4.1 is not so stable at the moment, or 
maybe its a problem with qemu......
Anyone knows something about that ?
I see that in the bugzilla there's some qemu-related bugs opened in the 
2007 and never closed (!!!)
Thanks
Marco
