I have a strange problem - xc_evtchn_status fails when running in HVM,
while exactly the same code (same kernel, same application etc) works
fine in PV. I've narrowed it down to copy_from_guest call in
common/event_channel.c, but no idea why it fails there. Xen version is
4.8.0. kernel is kernel-4.8.13-100.fc23. Any idea?
