Networkconfiguration with KVM

[Dan Johansson <kvm@dmj.nu>]

Hi,

I am new to this list and to KVM (and qemu) so please be gentle with me.
Up until now I have been running my virtualizing  using VMWare-Server. Now I 
want to try KVM due to some issues with the  VMWare-Server and I am having 
some troubles with the networking part of KVM.

This is a small example of what I want (best viewed in a fix-font):

  +-----------------------------------+
  | Host                              |
  |  +----------+                eth0 |---- 192.168.1.0/24
  |  |      eth0|-- +                 |
  |  | VM1  eth1|---(---+------- eth1 |---- 192.168.2.0/24
  |  |      eth2|---(---(---+         |
  |  +----------+   |   |   |         |
  |                 |   |   |         |
  |  +----------+   +---(---(--- eth2 |---- 192.168.1.0/24
  |  |      eth0|---+   |   |         |
  |  | VM2  eth1|-------+   +--- eth3 |---- 192.168.3.0/24
  |  |      eth2|-----------+         |
  |  +----------+                     |
  |                                   |
  +-----------------------------------+

Host-eth0 is only for the Host (no VM)
Host-eth1 is shared between the Host and the VM's (VM?-eth1)
Host-eth2 and Host-eth3 are only for the VMs (eth0 and eth2)

The Host and the VMs all have fixed IPs (no dhcp or likewise).
In this example th IPs could be:
Host-eth0:	192.168.1.1
Host-eth1:	192.168.2.1
Host-eth2:	-
Host-eth3:	-
VM1-eth0:		192.168.1.11
VM1-eth1:		192.168.2.11
VM1-eth2:		192.168.3.11
VM2-eth0:		192.168.1.22
VM2-eth1:		192.168.2.22
VM3-eth2:		192.168.3.22

And, yes, Host-eth0 and Host-eth2 are in the same subnet, with eth0 dedicated 
to the Host and eth2 dedicated to the VMs.

In VMWare this was quite easy to setup (three bridged networks).

Does someone know how I can set this up with KVM/QEMU?

Regards,
