Well diagnosed!

Indeed. I don't suppose you took a copy of the xend.log / xend-debug.log from
when the failure happened?

I don't think it was know before; thank you very much for reporting it.
I imagine Xen was trying to do some kind of IO in the process of starting the
domain, it was failing due to the filesystem being full, and it was being
misreported as "file not found". I guess it's possible the tools were
*actually* trying (and failing silently) to create a file somewhere, and then
not being able to find it subsequently.
This should (fingers crossed) be easy to replicate, though.
Cheers,
Mark
