Yes, this error probably should be made a bit more descriptive. It probably
hasn't got done yet because it doesn't come up often - just that when it does
it really confuses people!
The message says "segment" for historical reasons: the block backend used to
implement a basic LVM-style concatenated device abstraction. The devices the
guest saw were made up of "segments" of real disks. Since the restructure
for Xen 2.0 this is not necessary, since we can use real LVM where this
capability is required.

At some point, Xend acquired code to convert handle Linux-style devices even
if there aren't corresponding device nodes present - so it might Just Work
with the Linux device name.
Your devid looks OK, though.

Interesting. That device isn't mounted or something is it? If it is, the
tools should stop you using it, although IIRC they should produce a more
useful error message in this case.

Hmmm, weird. It might be worth poking in the Xen code and trying to figure
out where this error is coming from. Could it actually be an errno value?
