[libvirt] [PATCH] Fix virsh snapshot-list error reporting
by Jim Fehlig
Noticed that the expected "not supported" error is dropped when
invoking 'virsh snapshot-list dom' on a Xen installation running
the libxl driver
virsh snapshot-list test
error: Invalid snapshot: virDomainSnapshotFree
The error is overwritten by a call to virDomainSnapshotFree
in cleanup code within cmdSnapshotList. Prevent overwritting
the real error by not calling virDomainSnapshotFree with a NULL
virDomainSnapshotPtr.
---
This is one possible fix for the bug. The other would be to
silently return in virDomainSnapshotFree on a NULL
virDomainSnapshotPtr.

[libvirt] [PATCH 0/7] backport of getGroupList to v0.10.2-maint
by Eric Blake
https://bugzilla.redhat.com/show_bug.cgi?id=964358
Since it was on Fedora 18 that I first noticed the deadlock possible
when a child process calls getpwuid_r while the parent owned the
lock in a different thread, I'm interested in backporting my recent
work on virGetGroupList to v0.10.2-maint. However, I hit enough
conflict resolution that I'd like a review of my backport decisions
before pushing this to the stable branch.
Daniel P. Berrange (1):
Fix potential deadlock across fork() in QEMU driver
Eric Blake (6):
util: improve user lookup helper
util: add virGetGroupList
util: make virSetUIDGID async-signal-safe
security: framework for driver PreFork handler

[libvirt] [PATCH 0/5] Fix detecting cgroups at libvirtd restart with QEMU
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
The recent refactoring of cgroups broke the ability to detect
cgroups for running guests in the QEMU driver during libvirtd
startup. This was due to it not considering the existance of
the 'emulator' child group, as well as not honouring the
'cgroups_controllers' setting when it was present
Daniel P. Berrange (5):
Introduce a more convenient virCgroupNewDetectMachine
Make virCgroupIsValidMachine static
Fix detection of 'emulator' cgroup
Add 'controllers' arg to virCgroupNewDetect
Skip detecting placement if controller is disabled

[libvirt] Cannot compile libvirt
by Abhishek Sharma
Hi,
I am new to libvirt and I am trying to compile libvirt from the git
repository. I mainly plan to use it for managing ESX server. However I get
the following error during make.
*"libvirt undefined reference to virNetTLSInit"*
Here are the steps which I took.
1. Get the code. git clone git://libvirt.org/libvirt.git
2. Run autogen
./autogen.sh --without-xen --with-esx --without-numactl --without-remote
--without-libvirtd --without-one --without-openvz --without-qemu
--without-uml --without-phyp --without-vbox --without-lxc --without-one
--without-test --without-network --without-selinux --with-python
3. make
Looks like the following commit somehow separated the gnutls symbols.
*commit 83d7e4e4607a96b6959a6b0afd44a10a783fd928
Author: Daniel P. Berrange <berrange(a)redhat.com>
Date: Wed Mar 13 13:37:29 2013 +0000
Use separate symbol file for GNUTLS symbols*
How can I successfully compile libvirt ?
Thanks,
Abhishek

[libvirt] [PATCH v2] Don't overwrite errors in qemuTranslateDiskSourcePool
by Ján Tomko
Both virStoragePoolFree and virStorageVolFree reset the last error,
which might lead to the cryptic message:
An error occurred, but the cause is unknown
When the volume wasn't found, virStorageVolFree was called with NULL,
leading to an error:
invalid storage volume pointer in virStorageVolFree
This patch changes it to:
Storage volume not found: no storage vol with matching name 'tomato'
