Thanks for the heads up, kro. It appeared not to work for me before, but since I'm mostly playing around right now I'll try this again Be prepared to see a lot of hard reboot requests

If you use dummy0 with it's associated bridge (vmbr0) you don't need to use
NAT, you can simply route the IPs through the host.

By the way, I'm using Proxmox as they did a good job with the kernel to support both OpenVZ and QEMU (so you can run whatever you want, really - Windows included).

I prefer to use venet (non-bridged), as it'll allow you to either assign a (failover) IPv4 or IPv6 address directly, or you can hide it behind a firewall and NAT (in combination with Shorewall for example).

For KVMs (QEMU) you are reduced to veth (bridged) only - same if you need broadcasting on your OpenVZ container (like a DHCP server inside a container - as is the case with me). They too work fine for IPv4, but you cannot bridge it directly to eth0 (due to the multiple-MAC address issue this causes). If you do, you'll loose your connection and will have to correct that through the vKVM mode (I did that 3 times yesterday - DOH! ) So you must bridge it to "none" (OVH's default setup has it to "dummy0" for some reason) and use NAT.

As for IPv6 on a veth bridge, I'm still working on that - I need to a way to route and expose IPv6 to the public side without too much hassle, and so far I haven't had success... I have a feeling that'll be a "hack"

A MAC address can be changed, and so you could potentially spoof another person's server at OVH (internally, OVH most likely works predominantly with the MAC address, as this is fixed to the machine, whereas the IP address could potentially change over time).

No. They block the switch port as soon as they see any other MAC addresses.

Yes. See here for using Xen with routed networking.

I assume it also supports NAT, routed or host-only networking as it is listed here:

As above: Xen works great!

No. You can change the host name of your server and set the reverse DNS too.

You need to use host-only networking as OVH won't allow multiple MAC addresses.

You can view a brief guide here:
