Hello Luca, the recommended way to increase disk performance would be to use Xen PV disks. You just need to install the Windows PV drivers: http://www.xenproject.org/developers/teams/windows-pv-drivers.html But using VirtIO disk should also increase performance, even though most probably not as much.

I need to achieve maximum performance from this VM because of intense SQL tasks running in it. I've seen good improvement in IO on disk using VirtIO on a Windows VM onto a QEMU (QNAP) hypervisor, and i'm tryin to use this feature also on my Xen HV. Is VirtIO disk a good way to improve performance?
