[SOLVED] setting up a bridge with 3 static IPs and two VM

jbcolmena · 08-11-2010, 10:26 AM

Hi all,

I've been reading for days now, but can't find an example to the following. I have an ubuntu server, with two KVM virtual machines running ubuntu jeos. I want each VM to have it's own static IP, plus one IP for the server.

How on earth I do that? do I need to create two bridges, one for each machine? and if so, how do I assign static IP to each? I would greatly appreciate any hint.

Best regards.

Here is an example of the interfaces file for one bridge:

Quote:

auto lo
iface lo inet loopback

auto br0
iface br0 inet static
address 192.168.0.10
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.1
bridge_ports eth0
bridge_fd 9
bridge_hello 2
bridge_maxage 12
bridge_stp off

now, let's say the IP of my machine is 85.17.200.20, how do change the file? why at every example I see the same 192.168.0.1 address? I'm sorry if this too stupid, but well, I'm a newbie in this networks things. Have always used dhcp and never cared about IP addresses.
After that, how do I configure three IPs ?

anyone?

All I had to do was:
-set ONE bridge as shown in the ubuntu documentation.
-setting the static IP and all other network variables when creating the machines.

and that's it. Guess was just confused because all the examples I found where related to dhcp and not static IPs.

Best regards
