Simple network setup in KVM

[Joncak]

Hi, i trying to do something simple put 2 nic in the VM with different subnet example

eth0 = 200.62.X.X
eth1 = 10.10.X.X

the /etc/network/interface (KVM)

auto eth0
iface eth0 inet static
        address 200.62.X.X
        netmask 255.255.255.240
        network 200.62.X.X
        broadcast 200.62.X.X
        gateway 200.62.X.X
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 200.62.X.X
        dns-search domain.net


auto eth1
iface eth1 inet static
        address 10.10.1.9
        netmask 255.255.255.0
        bridge_ports vmbr0
        bridge_stp off
        bridge_fd 0

/etc/network/interface (NODE)

auto vmbr0
iface vmbr0 inet static
        address  10.10.1.2
        netmask  255.255.255.0
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0


auto vmbr1
iface vmbr1 inet static
        address  200.62.X.X
        netmask  255.255.255.240
        gateway  200.62.X.X
        bridge_ports eth1
        bridge_stp off
        bridge_fd 0

in the Past this config work but now when i try

ifup eth1 
Cannot find device "eth1"
Failed to bring up eth1.

I have a silly question for you Joncak: did you already add the new 'hardware' to the VM through the GUI?
What's the result of:
ip link show

Remove these lines from the KVM guest's config:

bridge_ports vmbr0
bridge_stp off
bridge_fd 0

so that it looks like this:

auto eth1
iface eth1 inet static
address 10.10.1.9
netmask 255.255.255.0


(That works for me at least - now I just need to work out how to get the private network NAT-ing)
