But after the upgrade, one of my guests will not start up. It gets stuck with 60-80% cpu use, almost no memory is allocated by qemu/kvm, and no output of any kind is seen (in the host console, or a bunch of the guest output options like curses display, stdio output, virsh console, vnc or sdl output). I normally use libvirt to manage the guests, but I've attempted to run qemu manually, and have the same problems. What can cause this? Just tested booting back into the old kernel, the one guest still won't start, while the rest do. I'm thoroughly confused. -- Thomas Fjellstrom thomas@fjellstrom.ca
