[PVE-User] WG: More than 1 virtual NICs in guest machine

[Max Jakob]

Thank you, guys, for your quick answers. It seems to be really easy, but 
anyhow it doesn't work for me as it should:

Here once more in detail my scenario:

My proxmox host server is limpopo. The guest host is polokwane.
I create a new NIC interface in the web gui according to your 
description. That creates an entry in the following file on limpopo 
(last line in the file):

limpopo:/etc/qemu-server# cat 137.conf
name: polokwane
ide2: local:iso/ubuntu-10.04.1-server-amd64.iso,media=cdrom
vlan0: virtio=32:5E:AB:B7:2C:0C
bootdisk: virtio0
virtio0: local:137/vm-137-disk-1.raw
ostype: l26
memory: 2048
onboot: 1
sockets: 1
vlan1: virtio=8E:37:A6:7E:65:D9


Then I restart the guest and would expect that a second NIC device 
(eth1) shines up here:

root at polokwane:~# ifconfig
eth0      Link encap:Ethernet  Hardware Adresse 32:5e:ab:b7:2c:0c
           inet Adresse:192.168.100.154  Bcast:192.168.100.255 
Maske:255.255.255.0
           inet6-Adresse: fe80::305e:abff:feb7:2c0c/64 
Gültigkeitsbereich:Verbindung

           TX packets:47 errors:0 dropped:0 overruns:0 carrier:0
           Kollisionen:0 Sendewarteschlangenlänge:1000
           RX bytes:10979 (10.9 KB)  TX bytes:6549 (6.5 KB)

lo        Link encap:Lokale Schleife
           inet Adresse:127.0.0.1  Maske:255.0.0.0
           inet6-Adresse: ::1/128 Gültigkeitsbereich:Maschine
           UP LOOPBACK RUNNING  MTU:16436  Metrik:1
           RX packets:0 errors:0 dropped:0 overruns:0 frame:0
           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
           Kollisionen:0 Sendewarteschlangenlänge:0
           RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)


But it doesn't. No second NIC. What's going wrong here? Or what's my 
error in reasoning?

Thanks for help.
