bridging and bonding network cards
I have a server that I'm going to start trialling KVM, it's running Ubuntu 9.0.4 & I have KVM
running OK but I'm having trouble getting my brain round how Ubuntu decides which netcard gets which
ip address & then how to setup bridging.
The server has 6 Gb cards, two onboard(currently eth0,eth1)that I'd like to keep for management etc
& a quad port card that I'd like to bridge two for virtual machines & bond two for access to our new
SAN when it arrives.
Currently I have configured the server with the two onboard ports (see interfaces file below) but I
can't get my brain round is how it's know's what IP address to give to each card (used to go by MAC
address) & how to setup the bridging & bonding bit for the quad port card, the server sees them OK
in /var/log/messages as eth2,3,4,5 but they aren't configured.
I have looked at loads on setting up the bridging but only on single cards not multiples so if
anyone could point me in the right direction I'd be very appreciative.
# This file describes the network interfaces available on your system

# The loopback network interface
auto lo eth0 eth1
iface lo inet loopback
# The primary network interface
iface eth0 inet static
# dns-* options are implemented by the resolvconf package, if installed
iface eth1 inet static
