[libvirt] [PATCH 00/12]
by Daniel P. Berrange 16 Oct '12

16 Oct '12

An update of https://www.redhat.com/archives/libvir-list/2012-August/msg00618.html Mostly this is a rebase to latest GIT. Alot of the questions raised with review last time bogged down on whether the APIs were design in the right way. I think I clarified their intended usage, so hopefully we can do code review this time :-) There are still a few more patches to add on to this - Serialize the tx/rx message queues so we don't loose partially sent/received messages across re-exec() - Make fcntl driver more configurable in its behaviour - Add support for leases based on LVM UUID and SCSI WWN
