Comment 1 for bug 187802

Thanks a lot for taking the time to report this problem and help us make Ubuntu better.
Unfortunately, VirtualIron is ot part of the targeted virtual environement for JeOS and the whole point of JeOS is to include as few drivers as possible to keep the kernel as lean as possible. I would suggest you to use our standard Ubuntu Server Edition if you would like to have all standard drivers enabled.
You can also try to use the ubuntu-vm-builder script that we are currently developping for hardy that you will find at https://launchpad.net/ubuntu-jeos. I will allow you to specify which kernel you want to include in your newle custom built vm.
