The Xen Project reports:

+
Certain PV guest kernel operations (page table writes in + particular) need emulation, and use Xen's general x86 instruction + emulator. This allows a malicious guest kernel which asynchronously + modifies its instruction stream to effect the clearing of EFLAGS.IF + from the state used to return to guest context.
+
A malicious guest kernel administrator can cause a host hang or + crash, resulting in a Denial of Service.
