While there's quite a bit of stuff under test, your recent vVMX series
would seem to be the most likely candidate for a regression here. I
am, however, puzzled by

(XEN) d1v0 VMLAUNCH error: 0
(XEN) domain_crash_sync called from vmcs.c:1712

in the L1 log - error 0 is supposed to be "no error", and I can't see
how VM_INSTRUCTION_ERROR would ever be written to zero.
Which leaves there being a path (which I can't spot) where it's not
being written, or a problem handling the respective vmread by the
guest.

Could you take a look, please?

Jan
