I had a similar problem and was able to rectify it by including the following line:

disk = [ 'phy:/dev/sda3,hda1,w' ]

which, as stated in the user doc in section 5.1, will export /dev/sda3 (the partition where my image is) to the domU as hda1.

then, my disk config is:

disk = [ 'file:/path/to/image,hda1,w' ]

also, the user doc's example in section 5.1 says that disk = [ 'phy:sda3,hda1,w' ] would work but it did not unless i put /dev/ in front of sda3, like above.

Xend does seem to start ok, and xm seems to run ok. But domU still can't find its boot disk. In the boot messages I see:

xen_blk: Initialising virtual block device driver

But following that I see no message like  Registering block device major 3
which I normally see on a working system.

The non-working system has python 2.3.4 on it. Could this be a problem?

My disk config is:
disk = [ 'file:/xen/disk-images/dom1.fs,sda1,w']
The strange thing is if I change the filename to something non-existent, the behavior stays the same. The disk image file does exist and is in good shape.
