I've just got an upgrade to KVM-58 as part of the latest Fedora.

Unfortunately my existing VM (a Windows 2008 Server instance) no longer boots. In fact it hardly gets anywhere at all. Immediately after running qemu-kvm, I just get a black screen (no BIOS/boot messages at all) and using 100% of CPU.

No kernel messages. 'strace' indicates that qemu-kvm is doing a lot of stuff (issuing lots of ioctl, gettimeofday, etc.).

I can get to the qemu monitor.  Are there any useful commands to issue?

'info blockstats' shows a single 512 byte read from ide-hd0, presumably it has read the boot sector but for some reason cannot boot from it.

Any ideas on what I can do to debug this further?

Try -clock unix. I'm not sure about the dyntick code.

No difference.

BTW, I'm fairly sure this isn't anything to do with the Windows guest, since it just doesn't get that far. It seems more likely to be down to the strange Intel development platform that I'm using. See attachments.
