[libvirt] vms hung
by Umar Draz
Hello,
I am running libvirt-2.0.0-10.el7_3.2.x86_64 on CentOS 7.3, I have few vms
of CentOS and Windows 2012 servers.
Randomly they are hung, but the status of virtual machine keep running, vnc
and network not responding.
I have checked all /var/log/messages and /var/log/libvirt/qemu/vm.log but
nothing found anything wrong.
Would you please help what should I do more so I can find the issue.

While local builds succeed fine, a build worker building in a
chroot environment is encountering the following error with

[libvirt] [PATCH] qemu: catch failure of drive_add
by Daniel P. Berrange
Previously when QEMU failed "drive_add" due to an error opening
a file it would report
"could not open disk image"
These days though, QEMU reports
"Could not open '/tmp/virtd-test_e3hnhh5/disk1.qcow2': Permission denied"
which we were not detecting as an error condition.

[libvirt] [PATCH] tests: fix QED disk test in xlconfigtest
by Jim Fehlig
When LIBXL_HAVE_QED is defined, xlconfigtest fails
9) Xen XL-2-XML Format disk-qed ... command line: config parsing error
in disk specification: no vdev specified in
`target=/var/lib/libvirt/images/XenGuest2,format=qed,backendtype=qdisk,vdev=hda,access=rw'
FAILED
As per the xl-disk-configuration(5) man page, target= must come
last in the disk specification when specified by name:
When this parameter is specified by name, ie with the target=
syntax in the configuration file, it consumes the whole rest of the
DISKSPEC including trailing whitespaces. Therefore in that case
it must come last.
Change tests/xlconfigdata/test-disk-qed.cfg to adhere to this
restriction.

The problem lies in how elements are appended into the transaction list -

[libvirt] [PATCH] qemu: Actually unshare() iff running as root
by Michal Privoznik
While all the code that deals with qemu namespaces correctly
detects whether we are running as root (and turn into NO-OP for
qemu:///session) the actual unshare() call is not guarded with
such check. Therefore any attempt to start a domain under
qemu:///session shall fail as unshare() is reserved for root.
The fix consists of moving unshare() call (for which we have a
wrapper called virProcessSetupPrivateMountNS) into
qemuDomainBuildNamespace() where the proper check is performed.

[libvirt] How to generate better API documentation?
by Michal Privoznik
Dear list,
now that we more or less agreed to use some new features (i.e. automatic free() when a variable goes out of the scope [1]), and with our NEWS efforts, do you think it is finally the right time to fix generation of our API docs too?
What I mean? Look here: [2] People use '@variable' notation hoping that the generator will put a link there. Or that our generator would allow us to:
typedef enum {
A = X,
B = Y,
C = Z,
# ifdef VIR_ENUM_SENTINELS
VIR_ENUM_LAST
# endif
} virEnum;
where X, Y, Z come from another enum.
Long story short, our documentation generator has a lot of bugs. What if instead of putting our effort in fixing it we would switch to something that is already available on the market? gtk-doc, doxygen, etc. Personally, I don't have any preference. Just want to know what your opinion is.
Again, if I get a green light I can put it onto the list of GSoC projects [3].
Michal

* change virStorageBackendGlusterCacheRefresh to *Release
* Avoid the global Flags
* Thread safe measure by using virCond*
Thanks Peter!
v4: Address review comments from Peter on v3

(qemuargv2xmltest, qemuxml2argvtest, qemuxml2xmltest and virstoragetest)
Patch 2: fix hung in qemuxml2argvtest
Patch 3 v3: Split this Patch to 2 parts as below
Patch 3 v4: don't free metadata used for storage driver access
Patch 4:
* update variable naming as per standards
* virStorageBackendGlusterPreopened* -> virStorageBackendGlusterCache*
Thanks Peter!
v3: Address comments by Daniel and Peter on v2
* Split the patch to 3 parts
Patch 1: change the virStorageNetHostDef type
Patch 2: optimize calls to virStorageFileInit and friends
Patch 3: add the caching for glfs
* Thanks to Daniel, this version make all the methods as thread safe
* Thanks to Peter for pointing use of virObjectLockable, this had simplified
rest of the parts a lot.
v2: Address review comments from Peter on v1
* Rebased on latest master
* Changes to commit msg
* Introduce storage API's for Register and Unregister of volume
* During qemu process Start/Stop and snapshot create
* Check Transport and Port type
* Atomic element add/del to list and ref counting
Pending: Treating IP and FQDN belong to same host
v1: Initial patch
