Personally I find it easier to just make .tar.gz files of the entire system. A few things you need to do to the fc image before you start. you want to install the xen kernel and make an entry for it in PyGrub before you move to step 1. fix the /etc/fstab to match what you call your disks in the xm config file. make sure the initrd you make has --preload xenblk make sure you run a getty on the console (for CentOS, the console is xvc0 I assume it is the same for fc) so add xvc0 to /etc/securetty and run a getty on it in /etc/inittab after this you can make the image as above. your config file needs to be something like this: bootloader = "/usr/bin/pygrub" memory = 512 name = "fc_test" vif =  disk = [ 'phy:/dev/sdaX,sda,w' ] it should 'just work'
