[libvirt] [PATCH] Fix logical storage pool operation on SLES10-SP2

The attached patch adjusts for a difference in behavior in the LVM utilities 'lvs' and 'vgs'. The SLES10-SP2 versions of these (and presumably others) append a trailing separator. This patch simply adjusts the regexps to allow (but not require) this. I thought just adding the ":?" to the regexps would do this, but this was leaving the trailing separator in the last group match, so I ended up tweaking the preceding group pattern as well. Dave
