[libvirt] [PATCH 0/7] Restore code to allow unpriv_sgio for hostdev SCSI generic
by John Ferlan 30 Jun '15

30 Jun '15

https://bugzilla.redhat.com/show_bug.cgi?id=1072736 This series of patches unreverts the functionality from commit id 'ce346623' which reverted the original functionality. Since pure revert caused too many conflicts and because the code has undergone a few changes since the prior reversion, I had to restore the code by rote method. The reversion includes some refactorings to make the final check much easier to handle. Of note patch 3 covers much of what was adjusted in the reverted patch 'qemuCheckSharedDevice'. Patch 4 expands the driver lock to cover the same space as the similar disk code - I can take the other as well and shorten the time the disk code has the lock. Keeping them similar is mostly a sanity thing. John Ferlan (7): qemu: Introduce qemuIsSharedHostdev qemu: Introduce qemuGetHostdevPath qemu: Refactor qemuCheckSharedDisk to create virCheckUnprivSGIO qemu: Refactor qemuAddSharedHostdev and qemuRemoveSharedHostdev qemu: Extract qemuGetHostdevPath from qemuGetSharedHostdevKey qemu: Add ability to set sgio values for hostdev qemu: Add check for unpriv sgio for SCSI generic host device src/qemu/qemu_conf.c | 205 ++++++++++++++++++++++++++++++++++----------------- 1 file changed, 138 insertions(+), 67 deletions(-) -- 2.1.0

[libvirt] [PATCH] vz: fix SDK event dispatching
by nshirokovskiy＠virtuozzo.com 30 Jun '15

From: Nikolay Shirokovskiy <nshirokovskiy(a)virtuozzo.com> Current version of SDK event dispatcing is incorrect. For most VM events (add, delete etc) issuer type is PIE_DISPATCHER.

[libvirt] Libvirt - updates backing file permission of qcow2 image on launching instance
by Agrawal, Ankit 30 Jun '15

30 Jun '15

Hi All, I am trying to fix a race condition between imagebackend and imagecache in nova (openstack) while creating an instance using qcow2 image backend. On creating a qcow2 image libvirt stores the base/backing file path reference while copying the image at instance disk info. While spawning the instance nova usage this base file reference as a backing file to launch instance. When base file is created in nova image cache directory its owner is set to openstack (a nova user) but on launching the instance from guest.launch, libvirt updates the base/backing file owner from openstack to libvirt-qemu which causes permission error if we try to use that base file later. Can someone please help me to understand why libvirt is updating the owner of base file stored in image cache directory, is it a bug in libvirt or the expected behaviour?
