Hi, all,
This is today's ABAT testing result against kvm.kernel
3415130f97a18f354853cab694d392553aa51af8 and kvm.userspace
a125fbfd00c18a6155afb75a3bf723d3faa2729d.
We found a new issue that 64bit host will crash when boot smp guest.
We didn't test pae host, because kvm cannot be built as exter

Did u try on lapic3 branch with XP guest? Only windows guest is using
string

With lapic3, we have kernel PIO emulation for PIC. Linux doesn;t
use string PIO for PIC (port 0x20/0x21) but XP
