[libvirt] Release of libvirt-1.2.17
by Daniel Veillard
So as planned I tagged it in git, development is open again, I signed
tarballs and rpms, they are at the usual place:
ftp://libvirt.org/libvirt/

[libvirt] [libvirt-glib PATCHv3 1/7] gobject: Simplify gvir_connection_list*() implementations
by Zeeshan Ali (Khattak)
Make use of virConnectListAll* functions to avoid making 4 calls and
hence avoid race conditions and complicated code.

[libvirt] ANNOUNCE: libvirt-sandbox "Dashti Margo" release 0.6.0
by Daniel P. Berrange
I pleased to announce the a new public release of libvirt-sandbox,
version 0.6.0, is now available for download
ftp://libvirt.org/libvirt/sandbox/
The packages are GPG signed with
Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R)
The libvirt-sandbox package provides an API layer on top of libvirt-gobject
which facilitates the cration of application sandboxes using virtualization
technology. An application sandbox is a virtual machine or container that
runs a single application binary, directly from the host OS filesystem.
In other words there is no separate guest operating system install to build
or manager.
At this point in time libvirt-sandbox can create sandboxes using either LXC
or KVM, and should in theory be extendable to any libvirt driver.
This release contains a mixture of new features and bug fixes
- API/ABI in-compatible change, soname increased
- Prevent use of virt-sandbox-service as non-root upfront
- Fix misc memory leaks
- Block SIGHUP from the dhclient binary to prevent
accidental death if the controlling terminal is
closed & reopened
- Add support for re-creating libvirt XML from sandbox
config to facilitate upgrades
- Switch to standard gobject introspection autoconf macros
- Add ability to set filters on network interfaces
- Search /usr/lib instead of /lib for systemd unit
files, as the former is the canonical location even
when / and /usr are merged
- Only set SELinux labels on hosts that support SELinux
- Explicitly link to selinux, instead of relying on
indirect linkage
- Update compiler warning flags
- Fix misc docs comments
- Don't assume use of SELinux in virt-sandbox-service
- Fix path checks for SUSUE in virt-sandbox-service
- Add support for AppArmour profiles
- Mount /var after other FS to ensure host image is
available
- Ensure state/config dirs can be accessed when QEMU
is running non-root for qemu:///system
- Fix mounting of host images in QEMU sandboxes
- Mount images as ext4 instead of ext3
- Allow use of non-raw disk images as filesystem
mounts
- Check if required static libs are available at configure
time to prevent silent fallback to shared linking
- Require libvirt-glib >= 0.2.1
- Add support for loading lzma and gzip compressed kmods
- Check for support libvirt URIs when starting guests
to ensure clear error message upfront
- Add LIBVIRT_SANDBOX_INIT_DEBUG env variable to allow
debugging of kernel boot messages and sandbox init
process setup
- Add support for exposing block devices to sandboxes
with a predictable name under /dev/disk/by-tag/TAGNAME
- Use devtmpfs instead of tmpfs for auto-populating
/dev in QEMU sandboxes
- Allow setup of sandbox with custom root filesystem
instead of inheriting from host's root.
- Allow execution of apps from non-matched ld-linux.so
/ libc.so, eg executing F19 binaries on F22 host
- Use passthrough mode for all QEMU filesystems
Thanks to everyone who contributed to this release
Regards,
Daniel

[libvirt] [PATCH v2 1/2] Fix nodeinfo output on PPC64 KVM hosts
by Shivaprasad G Bhat
The nodeinfo is reporting incorrect number of cpus and incorrect host
topology on PPC64 KVM hosts. The KVM hypervisor on PPC64 needs only
the primary thread in a core to be online, and the secondaries offlined.
While scheduling a guest in, the kvm scheduler wakes up the secondaries to
run in guest context.
The host scheduling of the guests happen at the core level(as only primary
thread is online). The kvm scheduler exploits as many threads of the core
as needed by guest. Further, starting POWER8, the processor allows splitting
a physical core into multiple subcores with 2 or 4 threads each. Again, only
the primary thread in a subcore is online in the host. The KVM-PPC
scheduler allows guests to exploit all the offline threads in the subcore,
by bringing them online when needed.
(Kernel patches on split-core http://www.spinics.net/lists/kvm-ppc/msg09121.html)
Recently with dynamic micro-threading changes in ppc-kvm, makes sure
to utilize all the offline cpus across guests, and across guests with
different cpu topologies.
(https://www.mail-archive.com/kvm@vger.kernel.org/msg115978.html)
Since the offline cpus are brought online in the guest context, it is safe
to count them as online. Nodeinfo today discounts these offline cpus from
cpu count/topology calclulation, and the nodeinfo output is not of any help
and the host appears overcommited when it is actually not.
The patch carefully counts those offline threads whose primary threads are
online. The host topology displayed by the nodeinfo is also fixed when the
host is in valid kvm state.
Test results with and without fix:

[libvirt] [PATCH] storage: add RBD support to disk source pool translation
by Thibault VINCENT
Hello,
We needed this to avoid redundancies when defining domains with RBD backends,
because monitor list and authentication secret could not be pulled from the
storage pool.
I didn't find any bit of documentation to update, actually it already implies
that disks with source type 'volume' would work with all kinds of backing
pools. But mpath, sheepdog, and gluster would still require an implementation
if it's possible.
Using RBD volumes this way still has a limitation, we cannot list snapshots in
libvirt pools. Whereas they could be accessed read-only if the domain is using
a network source explicitely with a 'snapshot' attribute.
How could we implement this so that snapshots are seen as pool volumes? There
are real use-cases for this like attaching to a VM a backup from it's own
disks. Also it would work the same way with ZFS snapshots, but AFAIK not for
LVM pools.
Cheers

Commit id 'f967e7a6' didn't place the closing parentheses quite right
causing DEADCODE errors since the rc setting/comparison was wrong.

[libvirt] [PATCH 0/2][1.2.17] qemu: fix address allocation on chardev hotplug
by Ján Tomko
For bug https://bugzilla.redhat.com/show_bug.cgi?id=1230039
Patch 1/2 fixes a regression in channel device hotplug which was introduced
in the last release and I would like to get it fixed before the next one.
Patch 2/2 is not that important, but still a bugfix.

[libvirt] [PATCH] conf: qemu: Taint VMs using custom device tree blob
by Peter Krempa
Using a custom device tree image may cause unexpected behavior in
architectures that use this approach to detect platform devices. Since
usually the device tree is generated by qemu and thus it's not normally
used let's taint VMs using it to make it obvious as a possible source of
problems.
