There's a couple of things wrong with that entry:
- the destination device has to have a /dev/ entry in the
domain where you run xend (i.e. /dev/hdx1 would have to exist in
dom0's filesystem).
- like with all devices, xend will prepend /dev/ to the device name.

For completeness, let me also mention that the destination
device has to be a hd or sd with an existing major number in
the domain where the device will be used.
(in 2.4, cciss might work as well ans here might be support for it to
be an xbd but that can go away anytime...).

It should work if you use:
disk = [ 'phy:hdb5,hdb5,w' , 'phy:hda6,hda6,w' , 'phy:vg0/rootvm101,sda1,w' ]
