RE: [Xen-devel] Error while creating domains

["Ian Pratt" <m+Ian.Pratt@xxxxxxxxxxxx>]

Add some debugging to print 'name' at the appropraite place. What's the
configuration file for this domain.

You might want to use the 'dry run' option just to print out the sxp the
domain config has been parsed in to. I suspect the block device name is
messed up.
