Host freeze at "virsh reset <domain>" or "virt-manager - Force

Need kernel.sysrq or power reset.
I don't believe this is a libvirt issue - the 'virsh reset' command
will issue the 'system_reset' QEMU monitor command. This in turn
does an immediate reset of the guest CPUs/machine.
Even if QEMU is doing the wrong thing, the kernel should obviously
never freeze/crash in this way - it should be robust against a
malicious QEMU process.
You should probably send this message to the main QEMU and/or KVM
mailing lists so that it comes to the attention of people who are
more familiar with QEMU + virtio-net

Daniel
