Hi Karl!
There are two possible solutions to this. First is to upgrade to the
latest patch, which fixes this (and speed up lhype significantly), or
boot the guest with "idle=halt".
The problem is caused by lhype not masking out the MWAIT capability, so
the guest thinks it can use that instruction (it can't).
Thanks for the bug report!
Rusty.
