[libvirt] Release of libvirt-1.2.11
by Daniel Veillard
It's out ! Tagged in git and signed tarballs and rpms are available
from the usual place:
ftp://libvirt.org/libvirt/
I also tagged and pushed a libvirt-python release too, to be found at:
ftp://libvirt.org/libvirt/python/
Overall this includes around 350 commits, 2 are security fixes, and
this also includes a couple of new generic features. There is of course
a number of improvement on various drivers, notably parallels, drvbhyve,
linux containers, xen migration, and kvm.
This also pack an impressive amount of bug fixes (nearly 100), so I
would really suggest to update when possible.

[libvirt] [PATCH v3] network: Bring netdevs online later
by Matthew Rosato
Currently, MAC registration occurs during device creation, which is
early enough that, during live migration, you end up with duplicate
MAC addresses on still-running source and target devices, even though
the target device isn't actually being used yet.
This patch proposes to defer MAC registration until right before
the guest can actually use the device -- In other words, right
before starting guest CPUs.
Signed-off-by: Matthew Rosato <mjrosato(a)linux.vnet.ibm.com>
---
Associated BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1081461
Changes for v3:
* Some minor formatting fixes.
* in qemuNetworkIfaceConnect, set VIR_NETDEV_TAP_CREATE_IFUP
unconditionally.
* in qemuDomainAttachNetDevice, call qemuInterfaceStartDevice only for
VIR_DOMAIN_NET_TYPE_DIRECT, _BRIDGE and _NETWORK.
* in qemuProcessStartCPUs, use 'reason' to determine whether or not
qemuInterfaceStartDevices needs to be called. Basically, it needs
to be called for any reason that the system would be initializing
(or re-initializing).

[libvirt] [PATCH] Avoid getting '-1:-1' in devices cgroup list
by Cédric Bosdonnat
When calling virCgroupAllowAllDevices we get these invalid entries
in the device cgroup config.
b -1:-1 rw
c -1:-1 rw
Check for positive values before outputting the major and minor to
avoid that.

[libvirt] [PATCH libvirt-python] Add c_pointer method to classes.
by Richard W.M. Jones
This returns the raw C pointer to the underlying object, eg:
conn = libvirt.open(None)
print "0x%x" % conn.c_pointer() # returns virConnectPtr of the connection
dom = conn.lookupByName("test")
print "0x%x" % dom.c_pointer() # returns virDomainPtr of the domain
The reason behind this is to allow us to transparently pass Python dom
objects through the libguestfs Python API.

[libvirt] Waiting for review of [PATCH v2 2/21] hyperv: implementation of virConnectGetVersion
by Yves Vinter
Hi All,
As I described the 27th of October in the following thread:
https://www.redhat.com/archives/libvir-list/2014-October/msg00840.html
[libvirt] [PATCH v2 0/21] hyperv: hyperv: set of new functionalities
new functionalities has been implemented in the libvirt hyperv driver as a set of 21 patches.
PATCH 01/21: hyperv: avoid query memleaks on failure
PATCH 02/21: hyperv: implementation of virConnectGetVersion
PATCH 03/21: hyperv: implementation of virConnectGetCapabilities
PATCH 04/21: hyperv: implementation of virDomainGetVcpus and virConnectGetMaxVcpus
PATCH 05/21: hyperv: implementation of virNodeGetFreeMemory
PATCH 06/21: hyperv: implementation of virDomainShutdown and virDomainShutdownFlags
PATCH 07/21: hyperv: implementation of virDomainGetSchedulerType and virDomainGetSchedulerParameters
PATCH 08/21: hyperv: implementation of virNetworkLookupByName
PATCH 09/21: hyperv: implementation of virNetworkGetXMLDesc
PATCH 10/21: hyperv: implementation of virConnectNumOfNetworks and virConnectListNetworks
PATCH 11/21: hyperv: implementation of virConnectNumOfDefinedNetworks and virConnectListDefinedNetworks
PATCH 12/21: hyperv: implementation of hypervInvokeMethod to handle complex parameters
PATCH 13/21: hyperv: implementation of virDomainSetAutostart and virDomainGetAutostart
PATCH 14/21: hyperv: implementation of virDomainSetMaxMemory
PATCH 15/21: hyperv: implementation of virDomainSetMemory and virDomainSetMemoryFlags
PATCH 16/21: hyperv: implementation of virDomainSetVcpus and virDomainSetVcpusFlags
PATCH 17/21: hyperv: implementation of virDomainUndefine and virDomainUndefineFlags
PATCH 18/21: hyperv: implementation of internal function hypervDomainAttachDisk
PATCH 19/21: hyperv: implementation of internal function hypervDomainAttachNetwork
PATCH 20/21: hyperv: implementation of virDomainAttachDevice and virDomainAttachDeviceFlags
PATCH 21/21: hyperv: implementation of virDomainDefineXML and virDomainCreateXML
A first version of this set has been submitted the 8th of October.
The first 3 patches have been already reviewed by Eric and the first patch has been pushed in the main stream.
Based on the remarks after this 3 reviews, I will produce a V2 for the whole set of patches.
It will be more convenient for me to submit V2 versions patch after patch, only after the previous one has been approved and pushed in the main branch.
The V2 of patch 02/21 has been submitted the 27th of October here:
https://www.redhat.com/archives/libvir-list/2014-October/msg00824.html
[libvirt] [PATCH v2 2/21] hyperv: implementation of virConnectGetVersion
I've not received any feedback since, and it has not been pushed in the main stream.
Is there any issue?
I'm still waiting for its approval before submitting the next patch...
Thanks for you answer,
Yves.

[libvirt] [PATCH] capabilities: Format <domain/> properly
by Michal Privoznik
The <domain/> element under /capabilities/guest/arch/ can have no
child elements. If that's the case we format:
<domain type='xen'>
</domain>
instead of simpler:
<domain type='xen'/>
This commit fixes that.

[libvirt] [PATCH v3] qemu: avoid rare race when undefining domain
by Martin Kletzander
When one domain is being undefined and at the same time started, for
example, there is a possibility of a rare problem occuring.
- Thread 1 does virDomainUndefine(), has the lock, checks that the
domain is active and because it's not, calls
virDomainObjListRemove().
- Thread 2 does virDomainCreate() and tries to lock the domain.
- Thread 1 needs to lock domain list in order to remove the domain from
it, but must unlock domain first (proper order is to lock domain list
first and the domain itself second).
- Thread 2 grabs the lock, starts the domain and releases the lock.
- Thread 1 grabs the lock and removes the domain from list.
With this patch:
- The undefining domain gets marked as "to undefine" before it is
unlocked.
- If domain is found in any of the search APIs, it's returned only if
it is not marked as "to undefine". The check is done while the
domain is locked.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1150505

Notes:
I marked this as v3, but it is basically a resend of v1 [1] with
s/undefining/removing/ change. I'm sending this even though the second
version of the patch got in again because the v2 that we pushed didn't
help. I got convinced [2] that doing this with a job fixes it, but it
doesn't, it just serializes the Create API after the Undefine API. The
only difference that the commit b629c64e [3] does is that it waits on
obtaining job, but not on locking the domain. That previous commit can
be reverted if anyone wants, I see almost no point in it being there
now.

[libvirt] [PATCH] qemu: Allow system pages to <memoryBacking/>
by Michal Privoznik
It occurred to me that OpenStack uses the following XML when not using
regular huge pages:
<memoryBacking>
<hugepages>
<page size='4' unit='KiB'/>
</hugepages>
</memoryBacking>
However, since we are expecting to see huge pages only, we fail to
startup the domain with following error:
libvirtError: internal error: Unable to find any usable hugetlbfs
mount for 4 KiB
While regular system pages are not huge pages technically, our code is
prepared for that and if it helps OpenStack (or other management
applications) we should cope with that.
