I would guess that this package would conflict with the kvm package and mess things up. Your error message mentions /usr/bin/qemu-system-x86_64 as the executable. If you run rpm -qf /usr/bin/qemu-system-x86_64 does it then tell you that this file belong to the qemu package? If so, I believe this is your problem...you try to use qemu, which has partial KVM support, instead of using qemu-kvm (which is the "real" KVM userspace executable that originates from the kvm package). I don't think the arguments supported by qemu-system-x86_64 and qemu-kvm are the same, which probably could be the cause of the client not booting and libvirt/virt-manager failing. Best Regards Kenni
