whitelist host virtio networking features
This patch is a followup to 8eca6b1bc770982595db2f7207c65051572436cb,
fixing crashes when guests with 2.6.25 virtio drivers have saturated
virtio network connections.
https://bugs.edge.launchpad.net/ubuntu/+source/qemu-kvm/+bug/458521
That patch should have been whitelisting *_HOST_* rather than the the
*_GUEST_* features.
I tested this by running an Ubuntu 8.04 Hardy guest (2.6.24 kernel +
2.6.25-virtio driver). I saturated both the incoming, and outgoing
network connection with nc, seeing sustained 6MB/s up and 6MB/s down
bitrates for ~20 minutes. Previously, this crashed immediately. Now,
the guest does not crash and maintains network connectivity throughout
the test.
