[libvirt] Looking for Outreachy sponsors for QEMU, libvirt, and KVM internships (was Outreach Program for Women)
by Stefan Hajnoczi
Outreach Program for Women is renaming to Outreachy. The new website
is: http://outreachy.org/
What is Outreachy?
Outreachy helps people from underrepresented groups join the open
source community
through a 12-week full-time paid internship.
The format is similar to Google Summer of Code. Instead of funding
university students
the focus is on funding women (cis and trans), trans men, and
genderqueer people.
Last year QEMU participated with one intern, Maria, who developed a
qcow2 image format
fuzzer to find input validation bugs in QEMU's qcow2 block driver.
GNOME, the Linux kernel community, and other projects have also been
participating
successfully for years.
What is the level of sponsorship?
Sponsorship is $6,500 per intern. Sponsors can choose their mentor if desired,
otherwise we have experienced mentors who can participate.
If your company wants to be active in growing the open source
community, this is a
great way to engage without administrating your own internship program!
Dates:
* Funding commitment: Monday, February 16
* Participating orgs announced: February 17
* Application deadline for interns: March 24
* Internship dates: May 25 to August 25
Sponsors are listed for recognition on the Outreachy website and can
promote job openings.
How do QEMU, libvirt, and KVM participate?
We try to participate in both Outreachy and Google Summer of Code each
year. QEMU acts
as an umbrella organization for libvirt and KVM. We have experienced
mentors and are able
to add new mentors who are active contributors to QEMU, libvirt, or KVM.
Full info for organizations:
https://wiki.gnome.org/Outreachy/Admin/InfoForOrgs
Please let me know if you have any questions.

[libvirt] [PATCH 0/8] qemu: support setting device's boot order when VM is running
by Wang Rui
QEMU supported to set device's boot index online recently(since QEMU 2.2.0).
http://lists.gnu.org/archive/html/qemu-devel/2014-10/msg00879.html
The QMP "qom-set" is available for setting boot index. qom-set's example is as follows:
{
.name = "qom-set",
.args_type = "path:s,property:s,value:q",
.mhandler.cmd_new = qmp_qom_set,
}
(qemu) qom-set nic1 bootindex 3
(qemu) qom-set nic1 bootindex -1
(qemu) qom-set scsi0-0-0-0 bootindex 2
Setting boot index to -1 means cancel it.
We can attach/update a device and set it's boot order when VM is running. The boot
order will take effect immediately(after guest rebooting). For example, we can use
'virsh update-device' to change an interface's boot order. The xml is specified as
below.
<interface type='bridge'>
<mac address='fa:16:3e:2e:d4:3d'/>
<source bridge='br0'/>
<target dev='tap4f2bce78-5b'/>
<model type='virtio'/>
<driver queues='4'/>
<boot order='2'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
If the 'boot order' is not specified in the xml, that means canceling its boot order.
Wang Rui (8):
qemu: add a new qemuMonitorSetBootIndex() method to set device's
bootorder
qemu: support attachment of net device with boot index
conf: check boot order which is used by itself
qemu: a code movement
qemu: support attachment of disk device with boot index
conf: add compatiblity check for boot index when updating device
qemu: support updating interface with boot index
qemu: support updating disk with boot index

[libvirt] [PATCH v2] Make tests independant of system page size
by Daniel P. Berrange
Some code paths have special logic depending on the page size
reported by sysconf, which in turn affects the test results.
We must mock this so tests always have a consistent page size.

[libvirt] [PATCH] virnetdev: fix some issues found by coverity and mingw builds
by Pavel Hrdina
Commit e562a61a introduced new function to get/set interface state but
there was misuse of ATTRIBUTE_NONNULL on non-pointer attributes and also
we need to wrap that functions by #ifdef to not break mingw build.

[libvirt] Missing libxl_device_nic settings
by Kim Larry
Hi,
I was trying to pass ip address to scripts/vif-bridge by putting <ip address=""/> in guest config xml file, however, I found that libxlMakeNic(which located in libxl/libxl_conf.c:956) doesn't set x_nic->ip. So I patched myself but I'm not so sure about VIR_DOMAIN_NET_TYPE_ETHERNET. It seems like vif-route, correct?
Here is my patch:

[libvirt] [PATCH] Make tests independant of system page size
by Daniel P. Berrange
Some code paths have special logic depending on the page size
reported by sysconf, which in turn affects the test results.
We must mock this so tests always have a consistent page size.

[libvirt] [PATCH] storage: Need to clear pool prior to refreshPool during Autostart
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1176510
When storageDriverAutostart is called path virStateReload via a 'service
libvirtd reload', then because the volume list in the pool wasn't cleared
prior to the call, each volume would be listed multiple times (as many
times as we reload). I believe the issue would be introduced by commit
id '9e093f0b' at least for the libvirtd reload path, although I suppose
the introduction of virStateReload (commit id '70da0494') could be a
different cause.
Thus like other places prior to calling refreshPool, we need to call
virStoragePoolObjClearVols

[libvirt] [PATCH] util: recheck the validating backend when the firewalld start/stop
by Luyao Huang
https://bugzilla.redhat.com/show_bug.cgi?id=1188088
When the firewalld is running and then start the libvirtd, libvirt
will set the current backend as VIR_FIREWALL_BACKEND_FIREWALLD.
But when firewalld is stop, we still try to use firewalld even it
is stopped, this will make the vm which has nwfilter cannot start
because systemd cannot find a running firewalld service.
We already have a Dbus callback functions before, add a recheck for
the validating backend in firewalld_dbus_filter_bridge and
nwfilterFirewalldDBusFilter callback functions to help us dynamic
change the validating backend.

[libvirt] [RFC] [Patch] Make hugepage testcase arch-agnostic
by Prerna Saxena
Hi,
I have attached this patch as a response to a recent failure observed on PowerPC architecture by commit
311b4a67.
This patch introduces a check for dynamically obtaining system page size for test hugepages-pages6 under 'qemuxml2argv' suite. ( See patch for more verbose problem description)
This patch is not the most perfect implementation -- it fails syntax check; and has a Makefile-driven cleanup pending. I will be happy to deck it up and send it if the community concurs with this
approach.
We could also implement this via a shell script ( just like 'virt-test-aa-helper') but I couldnt find an easy way to determine host page size.
Awaiting community responses,
Prerna
>From 8a64d4d22e2e65158d3caa45b615ca9a263f841f Mon Sep 17 00:00:00 2001
From: Prerna Saxena <prerna(a)linux.vnet.ibm.com>
Date: Mon, 2 Feb 2015 10:48:48 +0530
Subject: [PATCH] Commit 311b4a67 introduces a test for normal-page backed
guest XML. However, it hardcodes the page size to 4 KB which is only valid
for Intel Make check consequently fails on PowerPC where page size is 64KB
This makes the hugepages-pages6 test more modular, and enables the page size
to be picked up at runtime.
