[libvirt] [PATCH] qemu: process: Save vcpu ordering information on reconnect
by Peter Krempa
vCPU ordering information would not be updated if a vCPU emerged or
disappeared during the time libvirtd is not running. This allowed to
create invalid configuration like:
[...]
<vcpu id='56' enabled='yes' hotpluggable='yes' order='57'/>
<vcpu id='57' enabled='yes' hotpluggable='yes' order='58'/>
<vcpu id='58' enabled='yes' hotpluggable='yes'/>
Call the function that records the information on reconnect.

[libvirt] [PATCH] Report more correct information for cache control
by Martin Kletzander
On some platforms the number of bits in the cbm_mask might not be
divisible by 4 (and not even by 2), so we need to properly count the
bits. Similar file, min_cbm_bits, is properly parsed and used, but if
the number is greater than one, we lose the information about
granularity when reporting the data in capabilities. For that matter
always report granularity, but if it is not the same as the minimum,
add that information in there as well.

[libvirt] [PATCH] lxc: allow defining environment variables
by Cédric Bosdonnat
When running an application container, setting environment variables
could be important.
The newly introduced <initenv> tag in domain configuration will allow
setting environment variables to the init program.

[libvirt] [ISSUE go-xml] go-xml does NOT support DomainDisk marshal
by ZhenweiPi
Hi,
In the case of disk hot-plug, we need a xml like this :
/<disk type="file" device="disk">//
// <driver name="qemu" type="qcow2"/>//
// <source file="/root/vda.qcow2"/>//
// <target dev="vda" bus="virtio"/>//
// <address type='pci' domain='0x0000' bus='1' slot='20' function='0x0'/>//
//</disk>/
For now, go-xml does not support DomainDisk marshal.
Any good idea ?

[libvirt] [PATCH v4 0/3] Multiple cleanups within interfaceobj and interface driver
by John Ferlan
v3: https://www.redhat.com/archives/libvir-list/2017-May/msg01161.html
NB: The first 7 patches from v3 were pushed since they were ACK'd.
Difference in v4:
Patch 1 was essentially ACK'd, but I chose to hold onto it to show the context
Patch 2 is the new patch/context - move the @def processing into ObjNew
Patch 3 is mostly unchanged; however, I realized during processing of the
other code that with the model chosen in virInterfaceObjListAssignDef
to return an object that has had both the @lock and @ref incremented
so that callers can use the EndAPI to effectively Unlock and Unref
that means when calling virInterfaceObjListRemove all that's done
is a single Unlock/Unref leaving the object with still 1 reference
(and undeleted). That means the caller (testInterfaceUndefine)
must make that Unref call of the object. This is no different
than how Domain's work, although it's a bit more obtuse there because
callers of domain add will make that "second" reference to the object
and my goal in this is to be a bit more obvious...
The easier way to think about this is for objects only in one list,
when leaving the Add/Assign API's, there are 2 Refs and 1 Lock on
the object. For objects in 2 lists, there are 3 Refs and 1 Lock.
Each caller always calls EndAPI dropping a Ref and the Lock. When
it's time to Remove the object, a Find is done - which increments
a Ref and Lock and then the Remove API called. The Remove API will
effectively Unref for the object in a list (once or twice) and return
the Unlocked object w/ 1 Ref.
John Ferlan (3):
interface: Introduce virInterfaceObjNew
interface: Consume @def in virInterfaceObjNew
interface: Convert virInterfaceObj to use virObjectLockable

[libvirt] [PATCH] Capabilities: add step to cache control
by Eli Qiao
This patch adds cache control step size under control tag.
step is calculated by total_cache_size / cbm_length. This will be needed
while later doing cache allocation to calculate cbm bits.
Besides, count host's cbm length by counting bit instead of checking
cbm_mask length, along with test case updated.
