What is interesting is that it happens only with 32-bit guests and with
not-so fast hardware: Atom D510 for me and in your case MSI MS-7309 motherboard
(with what kind of processor?). I've a 64-bit hypervisor - not sure if you
are using a 32-bit or 64-bit.
I hadn't tried to reproduce this on the Atom D510 with a 64-bit Dom0.
But I was wondering if you had this setup before - with a 64-bit dom0?
Or is that really not an option with your CPU?
