[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] qemu: hotplug: Properly emit "DEVICE_DELETED" event when unplugging memory
by Peter Krempa
The event needs to be emitted after the last monitor call, so that it's
not possible to find the device in the XML accidentally while the vm
object is unlocked.

[libvirt] [ libvirt-python BUG ?] Memory leak in libvirt_virConnectDomainEventJobCompletedCallback
by Hailiang Zhang
Hi all,
It seems that, there is a memory leak bug in libvirt_virConnectDomainEventJobCompletedCallback()
function of libvirt-override.c.
We didn't decrease the reference of 'pyobj_dict' in this function or any other places
while pyt0bj_ret is not zero.
libvirt_virConnectDomainEventJobCompletedCallback()
{
... ...
pyobj_ret = PyObject_CallMethod(pyobj_conn,
(char*)"_dispatchDomainEventJobCompletedCallback",
(char*)"OOO",
pyobj_dom, pyobj_dict, pyobj_cbData);
Py_DECREF(pyobj_cbData);
Py_DECREF(pyobj_dom);
cleanup:
if (!pyobj_ret) {
DEBUG("%s - ret:%p\n", __FUNCTION__, pyobj_ret);
PyErr_Print();
Py_XDECREF(pyobj_dict);
} else {
Py_DECREF(pyobj_ret);
ret = 0;
}
LIBVIRT_RELEASE_THREAD_STATE;
return ret;
}
I don't think the reference of pyobj_dict will be stolen by PyObject_CallMethod
when it is passed to the Python function _dispatchDomainEventJobCompletedCallback.
In fact, we have a test which triggered lots of events and found that the memory
of the test process will keep raising slowly and could not be reclaimed
even we called gc.collect() explicitly in our codes.
So, is it a bug ? Any comments ?
Thanks,
hailiang

[libvirt] [V4] RFC for support cache tune(CAT) in libvirt
by 乔立勇(Eli Qiao)
hi all
Sorry for resend this again, I forget to add subject :( ...
Thanks all for the comment for previous RFC version, I summary all input
here also with Opens which I am not sure, can you please review again?
#Propose Changes
## Expose cache information into capabilities
Extend capabilities to expose all level cache resource information and
should tell the topology of caches also tell which kinds of resources can
be tuned/allocation
There information comes from
/sys/devices/system/cpu/cpu0/cache/index${level}/size
also /sys/fs/resctrl/ (this is CAT sys interface in linux kernel)
virsh capabilities
<cache>
<bank id='0, 'type="l3" size="56320" units="KiB" cpus="0,1,2,6,7,8"/>
<--------------------- level 3 cache is per socket, so group them by
socket id
<control unit="KiB" min="2816"/>
<bank id='1', type="l3" size="56320" units="KiB"
cpus="3,4,5,9,10,11"/>
<bank id='2' type="l2" size="256" units="KiB" cpus="0"/>
<bank id='3' type="l2" size="256" units="KiB" cpus="1"/>
<bank id='4' type="l2" size="256" units="KiB" cpus="2"/>
<bank id='5' type="l2" size="256" units="KiB" cpus="3"/>
<bank id='6' type="l2" size="256" units="KiB" cpus="4"/>
...
<cache>
Opens
1. how about add socket id to bank for bank type = l3 ?
2. do we really want to expose l2/l3 cache for now , they are per core
resource and linux kernel don't support l2 yet (depend no hardware)?
3. if enable CDP in resctrl, for bank type=l3 , it will be split to
l3data l3code, should expose this ability.
<bank type="l3" size="56320" units="KiB" cpus="0,1,2,6,7,8"/>
<--------------------- level 3 cache is per socket, so group them by
socket id
<control unit="KiB" min="2816" cdp="enabled"/>
## Provide a new API to get the avail cache on each bank, such as the
output are:
id=0
type=l3
avail=56320
total = ?? <--------- do we need this?
id=1
type=l3
avail=56320
id=3
type=l2
avail=256
Opens:
· Don't expose the avail cache information if the host can not do
the allocation of that type cache(eg, for l2 currently) ?
· We can not make all of the cache , the reservation amount is the
min_cbm_len (=1) * min_unit .
· do we need to expose total?
## enable CAT for a domain
1 Domain XML changes
<cputune>
<cache id="1" host_id="0" type="l3" size="5632" unit="KiB"/>
<cache id="2" host_id="1" type="l3" size="5632" unit="KiB"/>
<cpu_cache vcpus="0-3" id="1"/>
<cpu_cache vcpus="4-7" id="2"/>
<iothread_cache iothreads="0-1" id="1"/>
<emulator_cache id="2"/>
</cputune>
2. Extend cputune command ?
Opens:
1. Do we accept to extend existed API ? or using new API/virsh?
2. How to calculate cache size -> CBM bit?
eg:
5632/ 2816 = 2 bits
5733/ 2816 = 2 bits or 3 bits?
## Restriction for using cache tune on multiple sockets' host.
The l3 cache is per socket resource, kernel need to know about what's
affinity looks like, so for a VM which running on a multiple socket's host,
it should have NUMA setting or vcpuset pin setting. Or cache tune will fail.

[libvirt] [PATCH] 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] [PATCH] bhyve: fix interface type handling for argv2xml
by Roman Bogorodskiy
When generating a domain XML from native command (i.e. via
the connectDomainXMLFromNative call), we should use
interface type 'bridge' rather than 'ethernet' because we only
support bridges at this point.
As we don't have bridge name explicitly specified on the command line,
just use 'virbr0' as a default.

Hello everyone, and welcome to the libvirt Release Notes
Game, v3.0.0 edition!
Here's the deal: libvirt v3.0.0 is right around the corner,
and so it's about time we get the release notes into shape.
Most of the work has thankfully already been done during the
development cycle, by bundling release notes entries with
the code that implements the actual changes; however, some
changes have managed to fly under the radar so far. Not
documenting them properly in the release notes would be a
disservice to our users, and would undersell what is once
again a terrific release - I'd venture as far as calling it
the best one of 2017!
I've gone through all the commits between v2.5.0 and now,
and highlighted the changes that look like they should be
part of the release notes. Look for your name in the list
below, and spend a few minutes to craft a beautiful release
notes entry for each of the highlighted changes, then send
the patch to the list as usual. Feel free to CC: me for a
guaranteed[1] swift review!
Please note that, unlike you, I don't have intimate knowledge
of each and every line of code you've ever contributed to
libvirt, and as such might have misjudged the weight and
scope of the commits listed below, but that's the whole
point: the only person worthy of documenting a change in the
release notes is the author of the change himself! That said,
if you feel that any of the changes below should not end up
in the release notes feel free to raise an objection :)
Happy documenting! ^^

[libvirt] [PATCH for 3.0.x] Disable use of namespaces by default
by Daniel P. Berrange
When namespaces are enabled there is currently breakage when
using disk hotplug and when using AppArmor
Signed-off-by: Daniel P. Berrange <berrange(a)redhat.com>
---
I'm suggesting this for 3.0.x branch - we'll leave them enabled
in master on the basis that we'll actually fix the real bugs
there.

[libvirt] [PATCH] storage: avoid use of undefined GLUSTER_CLI variable
by Daniel P. Berrange
Previous commit tried to change configure logic such that the
GLUSTER_CLI parameter would always be set:
commit 9e97c8c0f0f3921d06bac2b92cd094a41373f748
Author: Peter Krempa <pkrempa(a)redhat.com>
Date: Mon Jan 9 15:56:12 2017 +0100
storage: gluster: Remove build-time dependency on the 'gluster' cli tool
This missed the fact that the AC_PATH_PROG call was itself inside an 'if'
conditional that would not be called in with_storage_gluster was false. As
a result, GLUSTER_CLI was still conditionally defined.
Just kill the GLUSTER_CLI parameter and AC_PATH_PROG call entirely and pass a
bare "gluster" string to virFindFileInPath instead.

Technically this is a build-break fix for FreeBSD, but I want to get a
review to double-check before pushing this.
