[libvirt] [PATCHv2] qemu: Emit domain events for all virtio-serial channels
by Matt Broadstone
Presently domain events are emitted for the "agent lifecycle" which
is a specialization on virtio-serial events specific to the channel
named "org.qemu.guest_agent.0". This patch adds a generic event for
"channel lifecycles", which emit state change events for all
attached channels.

[libvirt] question about connection between vms in two physical hosts
by 无敌浪子
Hi there,
I have some vms in two different physical hosts, the hosts are connected directly instead of a switcher, I'd like to make all these vms connected. the condition right now is that vm network type is nat, vm behind nat cannot get the new connection inbound, I suppose if I can make the inbound connection acceptable or if there is any other solution ? Thank you
best wishes

[libvirt] OSX Homebrew support note ;)
by Justin Clift
Hi all,
Compiling Libvirt directly from latest git master head is now supported
on
OSX Homebrew. It's as simple as:
$ brew install --HEAD libvirt
...
$ virsh -v
3.0.0
This should make development of Libvirt and related virtualisation
things
much easier on OSX. :)
The credit for this goes to Roman Bogorodskiy and Homebrew developer
"ilovezfs" (CC-d), for adding a functional rpcgen to Homebrew so we can
generate the needed RPC bindings during the build (previously missing).
Thanks heaps! :)
Regards and best wishes,
Justin Clift

[libvirt] [PATCHv4 0/3] Add support for file memorybacking
by Jaroslav Safka
Hi,
we would like to introduce 3 new elements source,access and allocation in memoryBacking element.
For now it was made for numa topology.
<memoryBacking>
<source type="file|anonymous"/>
<access mode="shared|private"/>
<allocation mode="immediate|ondemand"/>
</memoryBacking>
If allocation is immediate then -mem-prealloc should be added to the qemu commanline.
If source is file then
-object memory-backend-file,id=mem,size=1024M,mem-path=*lib dir path* -numa node,memdev=mem Will be added to the qemu commandline
If access is shared then the "share=on" parameter will be added to the memory-backend-file e.g.
-object memory-backend-file,id=mem,size=1024M,mem-path=/var/lib/libvirt/qemu,share=on
The access mode can be overriden by specifying token memAccess in numa cell.
The test cpu-numa-memshared was removed, because behaviour was changed and is not needed anymore
Jaroslav Safka (3):
qemu,conf: Rename virNumaMemAccess to virDomainMemoryAccess
conf: Add new xml elements for file memorybacking support
qemu: Add args generation for file memory backing

[libvirt] [PATCH] vz: don't show bootorder for containers
by Nikolay Shirokovskiy
Because this is invalid xml for containers. This patch almost
reverts 7eda8369, but still skips converting vz sdk bootorder
for containers to libvirt bootorder because we use boot order
in containers for quite different purpurse.

I know I reviewed this code just recently. It is just got out
of my sight.

[libvirt] [PATCH v3] qemu: set default vhost-user ifname
by Michal Privoznik
Based on work of Mehdi Abaakouk <sileht(a)sileht.net>.
When parsing vhost-user interface XML and no ifname is found we
can try to fill it in in post parse callback. The way this works
is we try to make up interface name from given socket path and
then ask openvswitch wether it knows the interface.

[libvirt] [PATCH v5 0/3] gluster: cache glfs connection object per volume
by Prasanna Kumar Kalever
v5: Address review comments from Peter on v4
Dropping Patch 3 from v3
Patch 1: fix transport type in all drivers, possible switch case converts
Patch 2: use virObject with src->drv to avoid 'initFlag' for
remembering 'virStorageFileInit' status
Patch 3:
* change virStorageBackendGlusterCacheQuery to *Lookup
* change virStorageBackendGlusterCacheRefresh to *Release
* Avoid the global Flags
* Thread safe measure by using virCond*
Thanks Peter!
v4: Address review comments from Peter on v3
Patch 1: changes to fix test failures
(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
Prasanna Kumar Kalever (3):
util: change the virStorageNetHostDef type
storage: optimize calls to virStorageFileInit and friends

[libvirt] Performance about x-data-plane
by Weiwei Jia
Hi,
With QEMU x-data-plane, I find the performance has not been improved
very much. Please see following two settings.
Setting 1: I/O thread in host OS (VMM) reads 4KB each time from disk
(8GB in total). Pin the I/O thread to pCPU 5 which will serve I/O
thread dedicatedly. I find the performance is around 250 MB/s.
Setting 2: I/O thread in guest OS (VMM) reads 4KB each time from
virtual disk (8GB in total). Pin the I/O thread to vCPU 5 and pin vCPU
5 thread to pCPU5 so that vCPU 5 handles this I/O thread dedicatedly
and pCPU5 serve vCPU5 dedicatedly. In order to keep vCPU5 not to be
idle, I also pin one cpu intensive thread (while (1) {i++}) on vCPU 5
so that the I/O thread on it can be served without delay. For this
setting, I find the performance for this I/O thread is around 190
MB/s.
NOTE: For setting 2, I also pin the QEMU dedicated IOthread
(x-data-plane) in host OS to pCPU to handle I/O requests from guest OS
dedicatedly.
I think for setting 2, the performance of I/O thread should be almost
the same as setting 1. I cannot understand why it is 60 MB/s lower
than setting 1. I am wondering whether there are something wrong with
my x-data-plane setting or virtio setting for VM. Would you please
give me some hints? Thank you.

The libvirt xml configuration file is like following (I only start
one VM with following xml config).
