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?

Rich.
