x86: unintended memory sharing between guests On Intel systems that support
the “virtualize APIC accesses” feature, a guest can read and write the
global shared xAPIC page by moving the local APIC out of xAPIC mode. Access
to this shared page bypasses the expected isolation that should exist
between two guests.
