But then I've never tried to run a kernel-2.2 VM. The OS type in virt-manager for linux 2.4 vs. generic isn't going to make much difference either. Maybe try switch the CPU model to some older type CPUs pentium2 etc, whatever was common around the time of that release. Perhaps also try switch domain type="qemu", occasionally kvm can interfere with things. Barring any of those, I'd try and build a qemu command line by hand that reproduces the issue, confirm with latest qemu, and mail qemu-devel about your issue. - Cole
