From b8fb68be37b9119e16b5fe88e76e2af34e586658 Mon Sep 17 00:00:00 2001 From: Chris Lalancette Date: Wed, 6 Aug 2008 11:26:47 +0000 Subject: [PATCH] DanB pointed out that my sexpr xend_internal patch from yesterday broke one of the regression tests. The problem is that the xenDaemonFormatSxpr{Disk,Net} functions are shared between domain creation time and attaching disk time. Unfortunately, though, Xend expects something different during these two times. During domain creation time, it wants the "(device" in front of the sexpr, while during attach time it does not. To remedy this situation, I added a flag to these two functions to differentiate between these two modes. With this patch in place, all of the regression tests pass.
