v2 of: https://www.redhat.com/archives/libvir-list/2018-July/msg00243.html Diff to v1: - Dropped 4/7 from the original series, as it's no longer needed - Reworked alias matching, instead of iterating through all disks trying to find a matching alias, retval of qemuDomainGetManagedPRAlias() is compared directly - The PR_MANAGER_STATUS_CHANGED event handling is done from worker pool rather than event loop. Patches 1 and 3 were ACKed already.

[libvirt] [PATCH] storage_util: Prefer generic FICLONE over btrfs/xfs defines
by Michal Privoznik 10 Jul '18

10 Jul '18

After my change to the original patch that resulted in commit 8ed874b39b3 it was brought to my attention that all three defines are the same: FICLONE = BTRFS_IOC_CLONE = XFS_IOC_CLONE. Therefore we should prefer generic FICLONE over 'specific' defines for btrfs/xfs.

[libvirt] [PATCH 0/5] Making libvirt aware of a server need
by Marcos Paulo de Souza 10 Jul '18

10 Jul '18

Hi guys, this is basically a second version of [1], but I rewrote the patch following Matthias ideas [2]. It really seems a cleaner change, but, feel free to suggest any other change that could make the code better. I did a lot of tests using virsh tool, so when using the ESX driver without a proper server, it returns a error. I could not test hyperv and phyp. Thanks, [1]: https://www.redhat.com/archives/libvir-list/2018-July/msg00393.html [2]: https://www.redhat.com/archives/libvir-list/2018-July/msg00400.html Marcos Paulo de Souza (5): driver.h: Add remoteOnly member to virConnectDriver struct libvirt.c: Return error when remoteOnly is set but server is empty esx_driver: Set remoteOnly member of virConnectDriver hyperv_driver: Set remoteOnly member of virConnectDriver phyp_driver: Set remoteOnly member of virConnectDriver src/driver.h | 2 ++ src/esx/esx_driver.c | 8 +------- src/hyperv/hyperv_driver.c | 8 +------- src/libvirt.c | 5 +++++ src/phyp/phyp_driver.c | 7 +------ 5 files changed, 10 insertions(+), 20 deletions(-) -- 2.17.1

[libvirt] [PATCH 0/5] Introduce new video model type 'none'
by Erik Skultety 09 Jul '18

09 Jul '18

Historically, we've always been adding a default video device onto the cmdline whenever a graphical framebuffer was requested but a video device was missing. With the appearance of mdev vgpus, having an emulated video device is suboptimal, especially with spice where the streaming client will by default open multiple windows, one for each video device (or 'head' in this case). Therefore, we should have a mechanism to disable the 'default video device addition' and this series does that by introducing a new video model 'none'. This can be applied and tried independently, however, it truly only makes sense on top of [1].
