Memory accessible by 64-bit PV guests under live migration

ISSUE DESCRIPTION On some hardware, during live migration of 64-bit PV guests, some parts of the guest's shadow pagetables are mistakenly filled in with hypervisor mappings. This causes Xen to crash when those mappings are later cleared. Before the crash, a malicious guest could use hypercalls to...
