[libvirt] [PATCH 0/7 RFC] RHEL-5 support, and a few preparatory fixes

This patch series attempts to make libvirt just work on RHEL-5. Right now it doesn't, mostly because libvirt relies on version number checks in a couple of places, and RHEL-5's version numbers aren't the whole truth due to various backports of later stuff. The first two patches are plain bug fixes: [PATCH 1/7] Fix network device inconsistency between xm and sxpr [PATCH 2/7] Fix graphics configuration inconsistency between xm and sxpr The next three add a few special cases for RHEL-5: [PATCH 3/7] New configure option --with-rhel5-api [PATCH 4/7] Fix HVM network device configuration for RHEL-5 [PATCH 5/7] Fix PVFB device configuration for RHEL-5 [PATCH 6/7] Enable NUMA support for RHEL-5 The last one drops a counter-productive error check: [PATCH 7/7] Don't treat missing topology information as error See the patches for more detailed descriptions. I'm not proposing this for immediate commit, as I'm still testing. But I'd appreciate review: is this the right way to do it? Thanks, Markus
