1. Trying to break it: Installed the SLES-11-SP1 with the parameters for SLES-10 causing it to use IDE disk instead of virtio. Runs fine though, IDE seems not to be the problem.
2. Trying to fix it: Compiled from the sources: commit da5361cc685c004d8bb4e7c5e7b3a52c7aca2c56 Mon Dec 12 17:21:34 2011 +0100 Had to copy the executable to /usr/bin/qemu-system-x86_64 moving aside the original first. Libvirt would not pick it up from a soft link, apparently failing in trying to auto-sense the version. Strange but inconsequential for the issue at hand.
