I may have spoken too soon: all of the above work, so providing a file
as a disk is fine. I just tried to provide a partition as a disk, and
once again no joy: (This is XEN3_DOMU with options BRIDGE_IPF)

and nothing more appears. xl list shows

The disk line is either:

disk = ['file:/scratch/disk.img,0x1,w'] <--- working

or

disk = ['phy:/dev/rraid6a,0x1,w']       <--- broken


(also tried with same results:
disk = ['format=raw, vdev=0x1, access=rw, target=/dev/rraid6a']       BAD
disk = ['format=raw, vdev=0x1, access=rw, target=/scratch/disk.img']  OK
)

Syntactic hints?

Cheers,
