[libvirt] [PATCH] util: Avoid libvirtd crash
by Alex Jia
In fact, the 'tapfd' is always NULL, the function 'virNetDevTapCreate()' hasn't
assign 'fd' to 'tapfd', when the function 'virNetDevSetMAC()' is failed then
goto 'error' lable, finally, the VIR_FORCE_CLOSE() will deref a NULL 'tapfd'.
* util/virnetdevtap.c (virNetDevTapCreateInBridgePort): fix a NULL pointer derefing.
* How to reproduce?

[libvirt] A couple of questions on snapshot-create/ snapshot-create-as
by Kashyap Chamarthy
Hi (Eric?),
I got a couple of questions for 'snapshot-create' / 'snapshot-create-as' :
1/ can '--disk-only' option (when used with virsh snapshot-create-as) be run on an offline
guest and generate an 'external snapshot' ? Or a running guest is needed?
2/ Can anyone point me to a bit more verbose info on these below options while creating
snapshots?
--quiesce quiesce guest's file systems
--atomic require atomic operation
--reuse-external reuse any existing external files
Thanks.

[libvirt] [PATCH] storage: Break out the loop if duplicate pool is found
by Osier Yang
It doesn't break out the "for" loop even if duplicate pool is
found, and thus the "matchpool" could be overriden as NULL again
if there is different pool afterwards.
To address the problem in libvirt-user list:

[libvirt] [PATCH] storage: Allow multiple hosts for a storage pool
by Wido den Hollander
The current storage pools for NFS and iSCSI only require one host to
connect to. Future storage pools like RBD and Sheepdog will require
multiple hosts.
This patch allows multiple source hosts and rewrites the current
storage drivers.

[libvirt] [PATCH] qemu: Make sure qemu can access its directory in hugetlbfs
by Jiri Denemark
When libvirtd is started, we create "libvirt/qemu" directories under
hugetlbfs mount point. Only the "qemu" subdirectory is chowned to qemu
user and "libvirt" remains owned by root. If umask was too restrictive
when libvirtd started, qemu user may lose access to "qemu"
subdirectory. Let's explicitly grant search permissions to "libvirt"
directory for all users.

[libvirt] libvirt stable releases
by Cole Robinson
Hi all,
An idea we've kicked around for awhile in Red Hat/Fedora land is doing
official libvirt stable releases, but nothing ever took shape. The idea was
brought up again recently and I've offered to help get something going.
I've pushed an upstream v0.9.11-maint branch with a bunch of patches
cherry-picked to libvirt 0.9.11. Shortly I'll be cutting a 0.9.11.1 and
pushing it to the website, like other releases.
Why 0.9.11? Because that's what we will be shipping in Fedora 17 :) Typically
our policy with fedora is to stick with one libvirt version for the length of
a release. Cutting stable releases should save us from having to backport
patches, and hopefully get us more bug fixes than backporting only what our
users report. So I don't plan on doing a similar branch for 0.9.12 or 0.9.13,
but will probably do a branch in 6 months time for whatever libvirt version we
are shipping in Fedora 18.
While my primary motiviation at the moment is making Fedora maintenance
easier, I hope that other distros will use the stable releases as well, where
we can all benefit from each others QA and attention.
Any feedback appreciated!
Thanks,
Cole

[libvirt] [PATCH] build: Fix version of gettext macros
by Peter Krempa
Commit c9cd419caba9effa11ca53e8696e5f6a4b424d60 added copying of the
makefile for translation files from gnulib. The makefile from gnulib is
of version 0.18 but the build configuration cretes macros from version
0.17 which breaks the build with message:
*** error: gettext infrastructure mismatch: using a Makefile.in.in from
gettext version 0.18 but the autoconf macros are from gettext version
0.17
