[libvirt] [PATCH v2 0/8] Add support for fetching statistics of completed jobs
by Jiri Denemark
Using virDomainGetJobStats, we can monitor running jobs but sometimes it
may be useful to get statistics about a job that already finished, for
example, to get the final amount of data transferred during migration or
to get an idea about total downtime. This is what the following patches
are about.
Version 2:
- changed according to John's review (see individual patches for
details)
Jiri Denemark (8):
Refactor job statistics
qemu: Avoid incrementing jobs_queued if virTimeMillisNow fails
Add support for fetching statistics of completed jobs
qemu: Silence coverity on optional migration stats
virsh: Add support for completed job stats
qemu: Transfer migration statistics to destination
qemu: Recompute downtime and total time when migration completes
qemu: Transfer recomputed stats back to source

[libvirt] [PATCH] conf: Skip generating random MAC in DetachDevice xml
by Kothapally Madhu Pavan
When we try to detach a network device without specifying
the mac address, random mac address is generated. As the
generated mac address will not be available in the running
vm, detaching device will fail erroring out "error:
operation failed: no device matching mac address
xx:xx:xx:xx:xx:xx found".

[libvirt] [PATCH 0/4] rpc: Fix fd leak and potential crash
by Cole Robinson
Patch 1 was already sent, I'd like to get it in for the release,
it should be quite safe.
Remaining patches centralize some cleanup code and fix a potential
crasher, but since it should be rare I'd like to wait till after
the release.
Previous thread: http://www.redhat.com/archives/libvir-list/2016-April/msg01618.html
Ben Gray (1):
rpc: Don't leak fd via CreateXMLWithFiles
Cole Robinson (3):
rpc: Add virNetMessageClearPayload
rpc: Clear more in virNetMessageClearPayload
rpc: use virNetMessageClearPayload in client

[libvirt] [PATCH v2] bhyve: implement domainShutdown
by Roman Bogorodskiy
Bhyve supports ACPI shutdown by issuing SIGTERM signal to the bhyve
process. Add the bhyveDomainShutdown() function and
virBhyveProcessShutdown() helper function that just sends SIGTERM to
VM's bhyve process. If a guest supports ACPI shutdown then process
will be terminated and this event will be noticed by the bhyve monitor
code that will handle setting proper status and clean up VM's resources.
Also, remove usage of virProcessKillPainfully() from domainDestroy.
First, it sends SIGTERM to the process that actually triggers ACPI reset
and that's not we want to do. Second, we're doing bhyvectl --destroy
later and it kills bhyve process, so there's no need to manually kill
it.
---
Changes from v1:
- Sending SIGKILL dropped completely for destroy due to reasons described
in the commit message. This is mainly based on the results of this (ongoing)
discussion:

[libvirt] RFC filesystem pool proposal description.
by Olga Krishtal
In this proposal description we would like to introduce a separate pool
type:fspool. Fspool provides and manages filesystems.
Below are listed possible examples of fspool, depending on source type:
volume, directory or network.
Volume fspool uses storage pool volume to reside upon.
<fspool type = 'volume'>
<name>fspool</name>
<uuid>cb07b799-8e03-485c-aaa0-7c88f60b37b0</uuid>
<allocation>0</allocation>
<capacity>0<capacity>
<source>
<pool ='pool name'/>
<volume='volume name'/>
<format type = 'ext4'/> (ext4, zfs - depending on type of volume that is used as a backend).
<source/>
<target>
<path>/path/to/fspool</path>
<permissions>
<mode>0777</mode>
<owner>0</owner>
<group>0</group>
</permissions>
</target>
</fspool>
Directory fspool represents a host directory:
<fspool type = 'dir'>
<name>fspool</name>
<uuid>cb07b799-8e03-485c-aaa0-7c88f60b37b0</uuid>
<target>
<path>/path/to/fspool/root</path>
<permissions>
<mode>0777</mode>
<owner>0</owner>
<group>0</group>
</permissions>
</target>
</fspool>
Network fspool is similar to previous one, except it is remote:
<fspool type='network'>
<name>fspool</name>
<uuid>b27a72b5-a92e-4e58-a172-a80ba73b30fe</uuid>
<source>
<host name='X.X.X.X'/> - if the pool is not on the host
<dir path='some/directory/exposed/to/our/host'/>
</source>
<target>
<path>/fspool</path>
</target>
</fspool>
basic API for fspool management:
fspool-define
fspool-build
fspool-start
fspool-stop
fspool-destroy
fspool-undefine
Fspools are divided into fs items. Single item is a directory inside the fspool root directory.
Fs item example is listed below:
<fs>
<name>item</name>
<allocation>0</allocation>
<capacity>0<capacity>
<source>fspool='name'</source>
<target>
<path>/fspool</path>
</target>
<permissions>
<mode>0777</mode>
<owner>0</owner>
<group>0</group>
<cgroups> Limits</cgroups>
</permissions>
</fs>
- allocation/capacity - is omitted when fspools type is directory.
- target path is a path to fs item from the fspool root. If it is not
present then the content of item is placed directly in fspool root.
- cgroups can be used in order to manipulate space usage politics.
Fs items will be manipulated via fs API:
fs-define
fs-delete
fs-list
In addition to containers use-cases, fspools are also useful for libvirt itself - they will help store and
easily manage some internal metadata, such as snapshots or internal connection driver information (logs, domain configurations, etc).
Please, take a look and share your opinion.

[libvirt] [PATCH 0/7] Admin API: Add support for client identity info retrieval
by Erik Skultety
This series adds support for client identity retrieval, i.e. information like
remote IP (if connected remotely), uid,gid,pid, as well as username if
connected locally and also information regarding authentication (if used).
The series is rebased on the listing clients series, because it relies on the
gendispatch stuff, so for testing purposes checkout my remote branch
https://github.com/eskultety/libvirt/tree/list-clients-info-disconnect which
also covers the next series about client disconnect.
Erik Skultety (7):
admin: Introduce virAdmServerLookupClient
admin: include: Introduce some client's identity related typed params
macros
virnetsocket: Provide socket address format in a more standard form
virneserverclient: Introduce virNetServerClientHasSASLSession
virnetserverclient: Add an internal method to retrieve client's
identity
admin: Introduce virAdmClientGetInfo API
virt-admin: Introduce command client-info

[libvirt] [PATCH v2] send default USB controller in xml to destination during migration
by Shivaprasad G Bhat
The default USB controller is not sent to destination as the older versions
of libvirt(0.9.4 or earlier as I see in commit log of 409b5f54) didn't
support them. For some archs where the support started much later can
safely send the USB controllers without this worry. So, send the controller
to destination for all archs except x86. Moreover this is not very applicable
to x86 as the USB controller has model ich9_ehci1 on q35 and for pc-i440fx,
there cant be any slots before USB as it is fixed on slot 1.
The patch fixes a bug that, if the USB controller happens to occupy
a slot after disks/interfaces and one of them is hot-unplugged, then
the default USB controller added on destination takes the smallest slot
number and that would lead to savestate mismatch and migration
failure. Seen and verified on PPC64.

[libvirt] [PATCH] dist: ln(1) is not guaranteed to have a '-f' option
by Andrea Bolognani
According to the autoconf manual, using '$(LN_S) -f' is not
portable; remove the target explicitly beforehand to work around
this limitation.
Adjust some slightly awkward indentation while at it.

[libvirt] [PATCH 0/3] qemu: support configuring usb3 controller port count
by Cole Robinson
This adds support for configuring the amount of usb ports on
qemu's usb3 controller. The default port count is 4 which is
kind of low, and when virt-manager starts using usb3 by default
we will likely up the port count to something like 8.
Cole Robinson (3):
qemu: parse: Use virControllerDefNew
qemu: caps: introduce QEMU_CAPS_NEC_USB_XHCI_PORTS
