That's hard to tell. My recommendation would be to try to install PV drivers to HVM guests if possible in order to get better performance. Performance of emulated nics is always going to be worse. Is the QEMU process in dom0 consuming lots of CPU when using the emulated nic? > I've been running pv guests for > years, but don't have much experience with hvm guests. > -thanks Guests using PV devices (that applies to HVM/PVH guests also) should always get better IO performance than those using emulated devices.
