Still somewhat new to this, I have a working Xen-3 dom0 (running under gentoo) - however I can''t seem to get my domU hosts working, and am at a point where I''m not sure where to look for further info. Trying the ttylinux image: config is: kernel="/root/vmlinuz.domU" memory=64 name="ttylinux" nics = 1 ip = "192.168.0.4" disk=[''file:/root/ttylinux-xen,sda1,w''] root="/dev/sda1 ro" booting gives (just the tail): Floppy drive(s): fd0 is unknown type 15 (usb?), fd1 is unknown type 15 (usb?) Failed to obtain physical IRQ 6 floppy0: no floppy controllers found Xen virtual console successfully installed as tty1 Event-channel device installed. xen_blk: Initialising virtual block device driver xen_net: Initialising virtual ethernet driver.

Are you able to mount it via the loop device under dom0 ? Or is it a diskimage so you would to have it define as "sda" for the domU.

I was somewhat lacking in details in the original post - It is an image, and it can be mounted under loopback on dom0. Also the config file is taken from my (working) Xen-2 setup, where prior to moving to Xen-3 it did work OK. The domU kernel was made using the Dom0 config (minus the privileged stuff). David.
