Oups, I am sorry, I am realizing that I made a typo in my original
message, I am only talking about dom0, not the VM. qemu-dm is leaking
memory, so if I only allocate 512MB to dom0 it will quickly run out of
memory. When I allocate more (4GB), I do not run out. At least until
now.

Pure HVM with emulated devices with qemu, I haven't looked at PV drivers.
