[libvirt] [PATCH v8] bhyve: add a basic driver

by Roman Bogorodskiy

Changes from v7: - Squashed in ACL support - Check for disk and bus type for bhyve and disk type for bhyveload - Handle case when URI == NULL in ConnectOpen - Call bhyveload only after we've built bhyve command to avoid unneeded load/reload for wrong domain configuration - Cleanup unload calls on errors - Minor style fixes Changes from v6: - Fix typo: s/LIBIVRT_DRIVER_RESULT_BHYVE/LIBVIRT_DRIVER_RESULT_BHYVE/ - Report domain state in 'dominfo' - Add a patch which implements ACL support Now both 'make check' and 'make syntax-check' pass.

[libvirt] [PATCH] RFC: Add blockdev-delete QMP command

This is the sister command to blockdev-add. In Fam's example he uses the drive_del HMP command to clean up but when trying to do this via libvirt it doesn't work.

[libvirt] [PATCH v3 0/2] Network hooks

by Michal Privoznik

Version three. The 1/3 from the previous round is already pushed (as it just reworks two functions - no interesting work really). The 1/2 from this patchset - I've moved the calling of the hook in networkStartNetwork() a bit forward, so now it's called before writing the network status file. This way it makes more sense. The 2/2 has been conditionally ACKed, but I'm sending it anyway just to make sure I got it right.

[libvirt] [PATCHv4 0/7] gluster snapshots and storage file operations via storage driver

This series is a new approach to using storage driver as file operations backend and uses the implemented functions to make snapshots on gluster work. Most of the patches are different to the previous version due to the refactor.
