Anything interesting printed before the crash?  My best guess by code
inspection is that nvmx->launched_list never got initialized, because of
some failure in vcpu init.

Also, if you have the xen-syms for this image, can you extract a
file/line-number for the crashing %rip (ffff82c4c01dd197)?
I'd expect it to be vvmx.c:150 or thereabouts.

And thirdly, can you try the attached patch?

Cheers

Tim.
