I am creating VMs using virt-install.  I can do so on a VM but it is very slow so I'd like to do on another "real" server but it is unable to download the kickstart file because it uses eth0.  How can I make it use a different interface such as br100?


# virt-install -n mick-testVm --hvm -r 2048 --vcpus=1 --os-variant=rhel6 -v --disk path=/images/mick-testVm.img,size=20 -l http://10.10.12.254/CENTOS6.4-x86_64-ES -x "ks=http://10.10.12.254/client_files/openstack/image-templates/mick-testVm/mick-testVm.cfg text console=tty0 utf8 console=ttyS0,115200"

I found and tried this earlier but it did not work.  Does it not configure the interface of the VM?  Need to force the host to use br100 to retrieve ks file.

Here is the issue and why it's failing.  I cannot route to ks server via eth0, only br100.

It worked using virbr0, which is set up when libvirt is installed.  I assumed it wouldn't as it has 192.168.122.1 address.  Anyway, good now so cheers.
