[libvirt] [PATCH 0/4] Alter Disk Volume logic to use objects
by John Ferlan 10 Jan '18

10 Jan '18

This series converts the storage volume forward linked list into an object that contains hash tables of volume objects. The first two patches resolve issues seen during testing with the Disk backend which had some special cased code to handle the Create/Delete paths and interactions with the partition logic. The first patch was much more quickly seen with object free logic in place. The second two patches make the conversion to objects and hash tables in "smaller chunks", but they could easily be combined.

[libvirt] [PATCH v2] nodedev: update mdev_types caps before dumpxml
by Wu Zongyong 09 Jan '18

09 Jan '18

In current implemention, mdev_types caps keep constant all the time. But, it is possible that a device capable of mdev_types sometime(for example:bind to proper driver) and incapable of mdev_types at other times(for example: unbind from its driver). We should keep the info of xml dumped out consistent with real status of the device.

[libvirt] [PATCH 0/4] apparmor: implement more domain callbacks

Instead of formatting 'MHz: 0', which can be confusing, skip the field altogether. This behavior is consistent with that of 'virsh nodeinfo'.

Hey there, is this patch already part of libvirt? As mentioned by DanielB. (https://stackoverflow.com/questions/46421962/from-qemu-to-libvirtvirsh-add-…) this feature is probably already implemented by now. If so, I really would like to use it, it would save me lot's of work. Is this feature already part of libvirt? If it is already implemented, how can I use it? If not, is this on schedule? Thx in advance! Xensemann
