The Xen Project reports:

+
VMX refuses attempts to enter a guest with an instruction pointer + which doesn't satisfy certain requirements. In particular, the + instruction pointer needs to be canonical when entering a guest + currently in 64-bit mode. This is the case even if the VM entry + information specifies an exception to be injected immediately (in + which case the bad instruction pointer would possibly never get used + for other than pushing onto the exception handler's stack). + Provided the guest OS allows user mode to map the virtual memory + space immediately below the canonical/non-canonical address + boundary, a non-canonical instruction pointer can result even from + normal user mode execution. VM entry failure, however, is fatal to + the guest.
+
Malicious HVM guest user mode code may be able to crash the + guest.

The Xen Project reports:

+
While INVLPG does not cause a General Protection Fault when used on + a non-canonical address, INVVPID in its "individual address" + variant, which is used to back the intercepted INVLPG in certain + cases, fails in such cases. Failure of INVVPID results in a + hypervisor bug check.
+
A malicious guest can crash the host, leading to a Denial of + Service.

Use of the feature, which is disabled by default, may have unknown + effects, ranging from information leaks through Denial of Service to + privilege escalation.
