As an aside: note that the attack the Xiao paper describes only works against Xen guests that *don't* use hardware-assisted page tables (EPT for Intel, NPT for AMD). If you're using hardware-assisted virtualization (e.g., most Amazon "HVM" instances), this particular attack won't work; others might, of course.
It also won't work if VMs don't share RAM, right?
RAM sharing is necessary for the Razavi et al. attack. The Xen attack is from Xiao et al. -=rsw
