Configuring second IP address in KVM virtual machine

[david314]

Hi,

I have installed Proxmox 2.2 in my server, and created a KVM virtual machine, shipped with Ubuntu Server 12.10. I need to configure a second IP address on this guest machine, so I add a new virtual network interface through the Proxmox control panel. The problem is that it does not get recognized by the guest machine, ifconfig -a just displays the first nic (eth0) and this is the output of lspci:

root@ubuntuserver1:~# lspci 
00:00.0 Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02)
00:01.0 ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II]
00:01.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II]
00:01.2 USB controller: Intel Corporation 82371SB PIIX3 USB [Natoma/Triton II] (rev 01)
00:01.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 03)
00:02.0 VGA compatible controller: Cirrus Logic GD 5446
00:12.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 20)

Any help would be appreciated.

You need to stop the VM, then start again (reboot is not enough).

So simple, so annoying.
