Arch domU (Xen) Internet connection without bridging

I have a dedicated server in OVH with Debian and Xen. Poorly, OVH doesn't allow to use bridge connection to any domU. Last time when I tried it, they blocked the whole server.
I try to get Internet connection in Arch domU. When I start network daemon, I get:

:: Starting Network                                 [BUSY] RTNETLINK answers: No such process
                                                    [DONE]

Networking part from rc.conf

HOSTNAME="yossarian"
interface=eth0
address=178.33.81.98
netmask=255.255.255.255
broadcast=178.33.255.255
gateway=46.105.121.254

From Arch domU:

From Gentoo domU (where connection works):
