[libvirt] [PATCH] nwfilter: Add ARP src/dst IP mask for ebtables ARP
by Stefan Berger
From: Stefan Berger <stefanb(a)linux.vnet.ibm.com>
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=862887
Add a netmask for the source and destination IP address for the
ebtables --arp-ip-src and --arp-ip-dst options. Extend the XML
parser with support for XML attributes for these netmasks similar
to already supported netmasks. Extend the documentation.

[libvirt] [PATCH] nwfilter: Fix rule priority problem
by Stefan Berger
From: Stefan Berger <stefanb(a)linux.vnet.ibm.com>
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1072292
Fix a problem related to rule priorities that did not allow to
have rules applied that had a higher priority than the chain they
were in. In this case the chain did not exist yet when the rule
was instantiated. The solution is to adjust the priority of rules
if the priority of the chain is of higher value. That way the chain
will be created before the rule.

[libvirt] [PATCH] hostdev: add virObject field to virHostdevManager struct
by Jim Fehlig
Commit 6b306d66 converted virHostdevManager to a virObject, but
missed adding a virObject field to the virHostdevManager struct.
Result is memory corruption when taking a reference on an instance
of the object, where atomic inc is done on the stateDir field.
Later use of stateDir crashes libvirtd.

[libvirt] How to build libvirt installation environment on ARM64?
by Chenqun (kuhn)
Hi all,
The libvirt can be used for ARM64? If it can be used for ARM64, what resources are needed for setup ?
How to build libvirt installation environment on ARM64?
I got some resource as follow:
1.ARM64 hardware is based Cortex-A57 fastmodel
2.Host and Guest kernel is linux 3.13.0
3.ARM64 filesystem from linaro releases (http://releases.linaro.org/latest/openembedded/aarch64/)
4.Qemu 1.6.50
5.Libvirt-1.2.0
My configure shell as follow：
export PKG_CONFIG=/usr/local/bin/pkg-config
export PKG_CONFIG_SYSROOT_DIR=/home/aarch64
export PKG_CONFIG_PATH=/home/aarch64/usr/lib/pkgconfig
./configure --target=aarch64 \
--prefix=/home/chenq/libvirt/install \
--host=aarch64-linux-gnu \
--libdir=/home/aarch64
CC=aarch64-linux-gnu-gcc \
LIBXML_CFLAGS="/home/aarch64/usr/lib"
CFLAGS="/home/aarch64/usr/include/libfdt"
LDFLAGS="/home/aarch64/lib"
Then configure error as follow：
…
checking for DEVMAPPER... no
checking for dm_task_run in -ldevmapper... no
checking libdevmapper.h usability... no
checking libdevmapper.h presence... no
checking for libdevmapper.h... no
configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt
I think this only one error is found. The libvirt depends on a lot of other libs,it will be find more similar errors.
So, how to create a friendly environment to compile and install libvirt on ARM64 ?
Thanks,

[libvirt] [PATCH v3] Add helper program to create custom leases
by Nehal J Wani
Introduce helper program to catch events from dnsmasq and maintain a custom
lease file per network. It supports dhcpv4 and dhcpv6. The file is saved as
"<interface-name>.status".
Each lease contains the following info:
<expiry-time (epoch time)> <mac> <iaid> <ip-address> <hostname> <clientid>
Example of custom leases file content:
[
{
"iaid": "1221229",
"ip-address": "2001:db8:ca2:2:1::95",
"mac-address": "52:54:00:12:a2:6d",
"hostname": "Fedora20",
"client-id": "00:04:1a:c1:d9:6b:5a:0a:e2:bc:f8:4b:1e:37:2e:38:22:55",
"expiry-time": 1393244216
},
{
"ip-address": "192.168.150.208",
"mac-address": "52:54:00:11:56:b3",
"hostname": "Wani-PC",
"client-id": "01:52:54:00:11:56:b3",
"expiry-time": 1393244248
}
]
src/Makefile.am:
* Add options to compile the helper program
src/network/bridge_driver.c:
* Introduce networkDnsmasqLeaseFileNameCustom()
* Invoke helper program along with dnsmasq
* Delete the .status file when corresponding n/w is destroyed.
src/util/leaseshelper.c
* Helper program to create the custom lease file

v3:
* Improved file handling, removed redundant copying, introduced --help and --version
v2:

[libvirt] [PATCH] Make ABI stability issue easier to debug
by Jiri Denemark
When ABI stability check fails, we only log the error message describing
the incompatibility. Let's log both XMLs in case of an error to make it
easier to analyze where and why the stability check failed.

[libvirt] [PATCH 0/7] Test parsing of iscsiadm output
by Ján Tomko
Introduce virCommandSetMockOutputFile for faking output of
asynchronous commands and use it to test parsing of iscsiadm
output in virStorageBackendISCSISession and
virStorageBackendISCSIScanTargets
Ján Tomko (7):
Change virStorageBackendISCSISession 'probe' arg to bool
Introduce virStoragePoolSourceDeviceClear
Use size_t for ndevice in pool source definition
Introduce vircommandpriv.h for functions used by tests
Add virCommandSetMockOutputFile
Add test for virStorageBackendISCSISession
Add a test for virStorageBackendISCSIScanTargets

[libvirt] [PATCH] qemu: Forbid "sgio" support for SCSI generic host device
by Osier Yang
The kernel didn't support the unprivileged SGIO for SCSI generic
device finally, and since it's unknow whether the way to support
unprivileged SGIO for SCSI generic device will be similar as for
SCSI block device or not, even it's simliar (I.e. via sysfs, for
SCSI block device, it's /sys/dev/block/8\:0/queue/unpriv_sgio,
for example), the file name might be different, So it's better not
guess what it should be like currently.
This patch removes the related code (mainly about the "shareable"
checking on the "sgio" setting, it's not supported at all, why
we leave checking code there? :-), and error out if "sgio" is
specified in the domain config.
