| Thread-topic: | Don't BUG when exitcode==-1. |
I had a bit of a problem getting PAE to work, and it made me see a exitcode == -1 from the VMRUN instruction. This caused the hypervisor to reboot, which I didn't think was a particularly good way to deal with an errant guest - the fault in my case was malformed PDPE's. The attached patch removes the BUG(), leaving the domain_crash_synchronous there, and adding a dump of the VMCB to aid debugging (although this doesn't actually help much when the PDPE's are wrong...) Applies to 10520. Please apply. Signed off by: Mats Petersson (mats.petersson@xxxxxxx) -- Mats
