Debian – Slow internet connection on one of two KVM guests (debian)

I don't think you need to implement anything special here. You just need create your guests with two interfaces, and bridge them to the private and public interfaces of the hosts. So long as the interfaces on the hosts are named and mapped the same way, your guests should retain the same public and private IPs on the same networks when they are migrated.

So after reading more on http://www.linux-kvm.org/page/Code#Debian they say "It is important to use more recent kernel - 2.6.26 does not work well with kvm"

so I ran below since I have 64bit (linux-image-2.6-686 for 32bit)

apt-get -t lenny-backports install linux-image-2.6-amd64

then rebooted and tried to create my vm again and it WORKED!

debian:~# virt-install --connect qemu:///system -n win2k3 -r 2048 -c /home/win2k3.iso -f /home/win2k3.img -s 20 --nonetworks --noautoconsole --vnc --os-type=windows --os-variant=win2k3 --hvm --accelerate

I hope this helps anyone who might stumble here.
