This bug is fixed by xen-unstable 11713:79b56c02b836 -- the VMX code was
not tracking writes to CR4 that happen when CR0.PE=0, so the second vcpu
was being shadowed in the wrong paging mode, and going into a PF loop.
Win2k3 (ee sp1 pae=1 acpi=1 apic=1 vcpus=2) doesn't complete the install
process yet, but gets as far as "Installing Devices" in the GUI
installer now.
