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.
