I'll check that tonight. Yep, I think modifying xendomains would be the
better way. Sorry that I overlooked your other day's question.
BR,
Carsten.

Thanks, I was just asking the other day who/what used that sxp output...
Personally think this behaviour of grepping the name out of the sxp is
pretty mad (I think an xl command to parse the configuration and output
a specific request field value would be far better) but in the interests
of xm compatibility does the following work for you?

xl: print sxp on dry-run of create.
The help text for xm create's --dry-run says "Dry run - prints the resulting
configuration in SXP but does not create the domain." so update xl
implementation to match.
