Comment 14 for bug 663191

I cannot really test the older kernel. I had problems with hibernate/resume, gave uswsusp a try and that has completely screwed up my file system. So I have a fresh install of Maverick since Wednesday (and therefore no older kernels). The kvm problem appeared with the fresh install. I had successfully booted my Windows XP on the Maverick that I still had on Monday (which was a Maverick by updates, starting with 9.04 -- if I remember correctly). That's why I tested the linux-generic first (see above), because updating from 9.04 to Maverick never updated the kernel from linux-generic to linux-generic-pae.

Good news (for me): 10 minutes ago I succeeded in booting Windows XP again. I changed the <emulator> stanza in the libvirt configuration from "/usr/bin/kvm" to "/usr/bin/qemu-system-i386".
