[libvirt] [PATCH v2] bhyve: Add support for VNC autoport
by Roman Bogorodskiy
From: Alexander Nusov <alexander.nusov(a)nfvexpress.com>
This patch adds support for automatic VNC port assignment for bhyve guests.
---
Changes from v1:
* Call virPortAllocatorRelease() in virBhyveProcessStop() to release
VNC port; that's done unconditionally of using autoport
* Call virPortAllocatorSetUsed(.., true) in virBhyveProcessReconnect()
to reserve already used VNC ports after daemon restart
* Call virPortAllocatorSetUsed(.., true) in bhyveBuildGraphicsArgStr()
for domains that don't use autoport so allocator didn't try to use
ports allocated by these domains
* In dryRun mode (i.e. for domxml-to-native) don't allocate any ports
* Add a couple of unit tests
Note 1: while adding tests I noticed that port allocator will actually
skip already bound ports, so I'm wondering if it makes any sense to use
virPortAllocatorSetUsed(.., true)? Right now I cannot come up with any
case to trigger this except probably some races when spawning guests
simultaneously, but that's hard to reproduce.
Note 2: there are still some cases where resources allocated during
command preparation are not properly cleaned up; that's not only VNC
ports, but also TAP devices. I plan to add proper cleanup routines
separately.

[libvirt] [PATCH RESEND] Interface: return appropriate status for bridge device
by Lin Ma
In function udevInterfaceIsActive, The current design relies on the sys
attribute 'operstate' to determine whether the interface is active.
For the device node of virtual network(say virbr0), There is already a
dummy tap device to maintain a fixed mac on it, So it's available and
its status should be considered as active. But if no anyelse tap device
connects to it, The value of operstate of virbr0 in sysfs is 'down', So
udevInterfaceIsActive returns 0, It causes 'virsh iface-list --all' to
report the status of virbr0 as 'inactive'.
This patch fixes the issue by counting slave devices for bridge device.

[libvirt] [libvirt-php PATCH 0/7] add bindings for NWFilter APIs
by Dawid Zamirski
Hello,
This series adds support for libvirt's virNWFilter* APIs. Since it
introduces new resource type, I took the opportunity to cleanup the
driver code a little:
* in patches 1-3: added macros to take care of the differences in how
PHP5 and PHP7 handle resource types.
* in patch 4: libvirt_doman_get_connect was segfaulting when called
multiple times because it was not bumping reference count on the
resource it was returning to the calling code.
* in patch 5: added a macro to take care of the differences in how PHP5
and PHP7 initialize arrays.
* patches 6 and 7: implement the missing binding to NWFilter APIs.
Dawid Zamirski (7):
move macros to header file.
add wrappers for PHP resource handling.
update code to use resource handling macros
fix libvirt_doman_get_connect implementation.
add and use VIRT_ARRAY_INIT macro
add nwfilter resource type
implement NWFilter API bindings.

[libvirt] [PATCH 0/3] libxl: Add a test suite for libxl_domain_config generator
by Jim Fehlig
Long ago danpb posted some patches to test libvirt domXML to
libxl_domain_config conversion
https://www.redhat.com/archives/libvir-list/2014-May/msg01102.html
Some of the prerequisite patches were pushed, but we've never managed
to push patches actually providing the conversion tests. I sent several
follow-ups to Dan's work but never converged on a satisfactory solution
for all the Xen versions supported by libvirt. The last attempt was in
Sept 2014
https://www.redhat.com/archives/libvir-list/2014-September/msg00698.html
I tried to revive the work in Jan 2015, but that also stalled
https://www.redhat.com/archives/libvir-list/2015-January/msg00924.html
Fast-forward over 2.5 years from the first attempt and libvirt no longer
supports older Xen versions 4.2 and 4.3 that were proving to be problematic.
Starting with Xen 4.5 libxl added support for libxl_domain_config_from_json,
which provides a way to implement the conversion tests that work with all
Xen versions >= 4.5 (including latest xen.git master).
The previous approaches compared a static json doc with the results of
domXML->libxl_domain_config conversion done in the libxl driver.
As discussed in those approaches, the json doc returned from
libxl_domain_config_to_json can change over Xen releases as the
libxl_domain_config object gains new fields, making it difficult to
compare the conversion with a static doc.
I had some time last week to pick at this thorn and reworked the test
to make use of libxl_domain_config_from_json introduced in Xen 4.5.
Instead of comparing the conversion results directly to a static json doc,
the static doc is first round-tripped through _from_json -> _to_json. Any
new fields added to libxl_domain_config object are then included in both
docs, allowing comparison across multiple Xen releases.
Patch3 provides the conversion tests using this new approach. The tests
are not run on Xen 4.4 (oldest version currently supported by libvirt)
since it does not provide libxl_domain_config_from_json.
Patches 1 and 2 fix some issues found while working on the tests.
See their commit messages for details.

[libvirt] [PATCH v3 00/16] virObject adjustments for common object
by John Ferlan
v2: https://www.redhat.com/archives/libvir-list/2017-June/msg00070.html
Pushed the first two patches from v2 since they were ACK'd
Changes in this series...
Fixed a couple of nits from former patch 3 & 4, but since they weren't ACK'd
they're here again, but now as patch 1 & 2.
Patch 3 & 4 are an adjusted version of the former patches 5 & 6. Instead
of going with generic @primaryKey and @secondaryKey names, this patch will
use @uuid and @name for the field names. Additionally instead of using
PoolableHashElement as a name, go with a much shorter LookupKeys. So
far the LookupKeys{UUID|Name} API's (patch 4) aren't used and could be
dropped if it's felt no future API would need them.
Former patches 7 & 8 dealing with the generic @def and @newDef object
were tossed away and the rest of the logic I'd be changing for virObject is
presented as the remaining (new to reviewers) patches 5 -> 16.
The object is named using LookupHash which is a follow-on of the LookupKeys.
If someone has better suggestion for names, then please provide suggestions
rather than just saying I hate the name! It's not my favorite name, but it
does convey what it is and IMO is better than just Element.
The patches also include the Interface object changes to illustrate that the
changes do work. I've run them through the various "interface" tests from the
Avocado VT test suite. I also did something similar for the Secret object in

[libvirt] [PATCH 00/16] Make the virNetworkObjPtr private
by John Ferlan
All part of the effort I have to have a common object model. This series
is network test, driver, and virnetworkobj related to work towards that
goal. By the last patch, the object is now private to virnetworkobj.c
John Ferlan (16):
test: Fix up formatting in network test API's
test: Use consistent variable names for network test driver APIs
network: Perform some formatting cleanup in bridge_driver
network: Use consistent naming in bridge_driver for virNetwork objects
network: Move macmap mgmt from bridge_driver to virnetworkobj
network: Add virNetworkObj Get/Set API's for @dnsmasqPid and @radvdPid
network: Alter virNetworkObj @class_id to be @classIdMap
network: Add virNetworkObj Get/Set API's for @floor_sum
network: Add virNetworkObj Get API's for @def and @newDef
network: Introduce virNetworkObj{Get|Set}Autostart
network: Introduce virNetworkObj{Is|Set}Active
network: Introduce virNetworkObjIsPersistent
network: Consistent use of @obj for virnetworkobj
network: Adjust virNetworkObjNew call and return
network: Modify naming for virNetworkObjList* fetching APIs
network: Privatize virNetworkObj

[libvirt] [PATCH RESEND] qemu: Remove inactive vm when failed to start it
by Yi Wang
Libvirt forgets to remove inactive vm when failed to start a defined vm.
That may result in residual domain in driver->domains on such condition:
during the process of starting a vm, undefine it, and qemu exit because
of some exception. As we undefined the vm successfully, the vm->persistent
was set to 0, we will always fail to undefine it until restart libvirtd.

[libvirt] [PATCH v2] qemu: Remove duplicated code in qemuBuildSerialChrDeviceStr()
by Andrea Bolognani
The call to qemuBuildDeviceAddressStr() happens no matter
what, so we can move it to the outer possible scope inside
the function.
We can also move the call to virBufferAsprintf() after all
the checks have been performed, where it makes more sense.

[libvirt] [PATCH 00/19] Start altering storage code to privatize of the object
by John Ferlan
Begin the process of making adjustments to the storage pool and volume code
in order to privatize the virStoragePoolObj and virStoragePoolObjList
Didn't want to post 40+ patches at one time... This is the first storage
pile including some test driver cleanups w/r/t storage code.
John Ferlan (19):
test: Fix up formatting in storage test API's
test: Use consistent variable names for storage test driver APIs
test: Cleanup exit/failure paths of some storage pool APIs
test: Add helpers to fetch active/inactive storage pool by name
test: Add testStorageVolDefFindByName for storage volume tests
storage: Fix return value checks for virAsprintf
storage: Use consistent variable names in virstorageobj
storage: Use consistent variable names for driver
storage: Alter volume num, name, and export API's to just take obj
storage: Create accessor API's for virStoragePoolObj
storage: Introduce virStoragePoolObjNew
storage: Introduce virStoragePoolObj{Get|Set}Autostart
storage: Move autostartLink deletion to virstorageobj
storage: Introduce storage volume add, delete, count APIs
storage: Introduce virStoragePoolObjForEachVolume
storage: Use virStoragePoolObj accessors for driver
storage: Use virStoragePoolObj accessors for storage test API's
storage: Use virStoragePoolObj accessors for storage_util
storage: Change storage_util to use obj instead of pool
