Subject Re: how to create guest with /dev/vda ROOT volume?

Thanks, Kirk,  that make it to work for manual installation !

Now the next logic question is how to make this work with kickstart ?  In
our environment, we normally use kickstart to (re)build all nodes, so it
would be extremely helpful to get kickstart working for VM¹s as well.
