The remote FreeBSD host is missing a security-related update.
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.
