I have at least two problems running a virtual machine on F7 1. Running qemu from hte command line means I can create a virtual disk, run a virtual machine and install Windows XP on it. I can do this because it enables me to define the cdrom on the command line with "-cdrom /dev/cdrom". But I can't get any further because it keeps giving me an error saying "A problem is preventing Windows from accurately checking the license for this computer" If I run the same virtual machine from the virtual machine manager I don't get that error. But I don't get the CD ROM either 2. The above was obtained with QEMU. If I try to connect the Virtual Machine Manager to XEN I get an error that tells me that either I'm not running a XEN-enabled kernel, or the XEN service isn't running. Unfortunately, it is running! Any advice from anyone on either of these? I would love to do away with dual-booting my laptop and just run Vista in a VM when I need it, but so far I'm not having a lot of luck. JDL
