Just to be sure I'm not misunderstanding, are you saying that running an HVM
machine without PV drivers makes it impossible to avoid packets drops? So
this means there's no way to have a fully functional (=a machine that's
perfectly usable, regardless of its performance) HVM machine without PV
drivers?

I just run some tests following your hints, and my server without xen runs
fine, with the xen kernel no vms runs fine, the problem comes in a non-PV
HVM guest only.
