[libvirt] [PATCH 0/4] Clean up machineName-related code
by Martin Kletzander
Just in case we'll want to use the "cleaned-up" machineName for
anything else in the future, I decided to modify the code so that it
is always generated, saved and cleaned-up. While doing that I
identified some code duplication, leak and a TODO/XXX comment that are
all fixed with this series. And it only adds four lines overall!
Martin Kletzander (4):
conf: Pass config.priv to xmlopt->privateData.alloc
qemu: Save qemu driver in qemuDomainObjPrivateData
lxc: Make lxcProcessStop callable even without PID being available
Move machineName generation from virsystemd into domain_conf

[libvirt] [PATCH] Revert "virthread: Introduce virRWLockInitPreferWriter"
by Michal Privoznik
This reverts commit 328bd24443d2a345a5832ee48ebba0208f8036ea.
As it turns out, this is not portable and very Linux & glibc
specific. Worse, this may lead to not starving writers on Linux
but everywhere else. Revert this and if the starvation occurs
resolve it.

[libvirt] [PATCH] qemu: fix migration fail of an auto-placement vm after attached memory to it
by Yi Wang
This patch fix this condition:
-vm has the "auto" placement in vcpu
-hot-plug memory with source node "1-3" through attach-device command
-migrate the vm to a host with only 2 numa node
And the migration will fail with error:
"error: unsupported configuration: NUMA node 2 is unavailable"

[libvirt] [PATCH v3 0/4] Fix a couple issues found w/ vHBA logic
by John Ferlan
v2: https://www.redhat.com/archives/libvir-list/2017-July/msg00661.html
Changes since v2:
* Patch 1 - make the requested logic adjustment
* Patch 2 - no change
* Patch 3 - make this *just* the check that the provided @parent_name
is a valid fc_host (whether it's vHBA or HBA).
* Patch 4 - Alter the checkParent logic to cause a failure if the
passed @name (from the wwnn/wwpn's provided) are for an
HBA instead of a vHBA. Make this an invalid configuration.
Modify the docs to describe that the provided wwnn/wwpn
must be for an existing vHBA, are to be used to create a
vHBA, but cannot be from an existing HBA.
NB: No change to the Destroy code since it's possible one
of these exists and there needs to be a way to shut it down.
The failure could turn into a "conversion" of sorts as well
by changing the type to 'scsi_host', saving the generated
scsi_host name, removing the parent and wwnn & wwpn fields.
Tested using my vHBA system with various valid and invalid configurations.
John Ferlan (4):
storage: Fix existing parent check for vHBA creation
storage: Remove @conn from virNodeDeviceCreateVport
storage: Check if provided parent is vHBA capable
storage: Disallow usage of the HBA for a fc_host backing

Currently, the maximum tolerable downtime for a domain being migrated is
write-only. This patch implements a way to query that value nondestructively.
Changes from [v1]:
* Fixed formatting and style problems
* Add additional JSON error check
* Better patch submission mail, I hope

[libvirt] [PATCH v6 0/4] Make virNodeDeviceObj and virNodeDeviceObjList private
by John Ferlan
NB: Like v5, keeping same title for consistency
v5: https://www.redhat.com/archives/libvir-list/2017-July/msg00610.html
Changes since v5:
* Replace patch 1 w/ the aha moment from review. The deletion API's
don't need to use virNodeDeviceObjListGetParentHost. Instead they
can just use virNodeDeviceObjListFindByName as the parent_wwnn/wwpn
and parent_fabric_wwn are not stored in the vHBA. They're merely for
the purpose of creation. The vHBA *does* store the def->parent by
name and we can use that instead
* Add patch 2 in order to remove the CREATE_DEVICE boolean from
virNodeDeviceObjListGetParentHost as it won't be necessary since
the only consumers are now CreateXML callers
* Modify patch 3 calls to virHashSearch to add a NULL parameter since
commit '38e516a52' added this (a real buzzkill for other changes too)
* Modify patch 4 to include removing the locks in Nodedev calls for
test_driver as well.
John Ferlan (4):
nodedev: Alter node device deletion logic
nodedev: Remove @create from virNodeDeviceObjListGetParentHost
nodedev: Convert virNodeDeviceObjListPtr to use hash tables
nodedev: Remove driver locks around object list mgmt code
