Re: creating a linux domU

	hello Iain. I wonder if part of your confusion has to do with a logic
error I found in the xentools-4.12.1 sources.  The following patch made
libxl behave as the manual described.  Without the patch, I couldn't get
pvh domu's to boot at all.
Here's the patch, for future reference.
-thanks
