Short version, I had to run mkinitrd with ext3 support. Some issues remain - especially the failure to load modules - see below log - and networking is not fully functional. Brian Long post ahead if you are interested My config disk = [ 'file:/etc/xen/fedora/fedora.fc5.img,hda1,w' , 'file:/etc/xen/fedora/fedora.swap,hda2,w' ] memory = 256 vcpus = 1 builder = 'linux' name = 'vm2' vif = [ 'mac=00:16:3e:34:8f:88' ] localtime = 0 on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' extra = ' TERM=xterm' #bootloader = '/usr/lib/xen/boot/domUloader.py' #bootentry = 'hda6:/boot/vmlinuz-xen, /boot/initrd-xen' kernel = "/boot/vmlinuz-xen" ramdisk = "/boot/initrd-xen" root = "/dev/hda1 ro" In an earlier post you can see boot complains about ext3 when trying to read the fedora5 image file.
