This patch implement virtio network device.
Use '-n virtio or --network=virtio' to enable it.
The current implementation uses tap which needs root privileges to create a
virtual network device (tap0) on host side. Actually, what we need is
CAP_NET_ADMIN.
The host side tap0 is set to 192.168.33.2/24.
You need to configure the guest side eth0 to any ip address in
192.168.33.0/24.
Here are some scp performance test for differenct implementations:
None of rx and tx as thread:
guest to host 3.2MB/s
host to guest 3.1MB/s
Only rx as thread:
guest to host 14.7MB/s
host to guest 33.4MB/s
Both rx and tx as thread(This patch works this way):
guest to host 19.8MB/s
host to guest 32.5MB/s
