Sorry? There's nothing wrong with going for pvpanic as a simple
implementation.

There have been IPMI patchsets on qemu-devel though, and SUSE will be
investigating adding some IPMI support too (not sure if identical to the
scope of those patchsets), whether IPMI is complicated or not. It's a
standard present on physical servers, facilitating unified management of
virtual and physical servers, and there's OpenIPMI as implementation.

My point was, there may be alternative, non-PV implementations to suck
such information out of a guest, IPMI being one example of a management
interface that exists for physical servers. So it's not necessarily
black-or-white, but choices similar to virtio vs. IDE vs. AHCI vs. SCSI.

HTE,
Andreas
