[libvirt] [PATCHv2 1/2] virsh: move command cpu-baseline from domain group to host group.
by liyang
From: Li Yang <liyang.fnst(a)cn.fujitsu.com>
cpu-baseline command can compute baseline CPU for a set of given CPUs,
I think it should not belong to domain group, should belong to host
group, so I moved the related source from virsh-domain.c to virsh-host.c

[libvirt] [PATCH] virnetsocket: fix getsockopt on FreeBSD
by Ryota Ozaki
aa0f099 introduced a strict error checking for getsockopt and it
revealed that getting a peer credential of a socket on FreeBSD
didn't work. Libvirtd hits the error:
error : virNetSocketGetUNIXIdentity:1198 : Failed to get valid
client socket identity groups
SOL_SOCKET (0xffff) was used as a level of getsockopt for
LOCAL_PEERCRED, however, it was wrong. 0 is correct as well as
Mac OS X.
So for LOCAL_PEERCRED our options are SOL_LOCAL (if defined) or
0 on Mac OS X and FreeBSD. According to the fact, the patch
simplifies the code by removing ifdef __APPLE__.
I tested the patch on FreeBSD 8.4, 9.2 and 10.0-BETA1.

[libvirt] Entering freeze for libvirt-1.1.4
by Daniel Veillard
I finally tagged and genrated tarballs for RC1 of 1.1.4, so we have
now entered freeze. The bits are available as usual at:
ftp://libvirt.org/libvirt/
My initial testing doesn't show anything suspicious but is limited,
so please give it a try, especially for portability issues !
If all goes well i will probably make an rc2 by Thurday and release
1.1.4 for good on Monday 4th.
Give it a try !
thanks,
Daniel

[libvirt] Erratic failure of
by Daniel Veillard
While building the release my first rpm build failed with
FAIL: securityselinuxtest
i.e. rpmbuit -ta based on libvirt-1.1.4 tarball on an up to date
Fedora release 19, it did not reproduce (subsequent builds just
worked fine) so i don't really have clues of what happened, except
I didn't caught anything in my logs either. That didn't happen for
rc1 or rc2 but that could be just pure luck .
Sorry for the lack of details,
Daniel

[libvirt] [PATCH] MacOS: Handle changes to args in xdrproc_t
by Doug Goldstein
With Mac OS X 10.9, xdrproc_t is no longer defined as:
typedef bool_t (*xdrproc_t) (XDR *, void *, ...);
but instead as
typedef bool-t (*xdrproc_t) (XDR *, void *, unsigned int);
The rationale explained in the header is that using a vararg is
incorrect and has a potential to change the ABI slightly. They decided
to specify the exact number of parameters and for compatibility with old
code decided to make the signature require 3 arguments. The third
argument is ignored for cases that its not used and its recommended to
supply a 0.

[libvirt] [RFC PATCHv2 0/2] gluster pools
by Eric Blake
This addresses the review from RFCv1 for splitting the glfs checks
to be different from the storage backend checks:
https://www.redhat.com/archives/libvir-list/2013-October/msg00645.html
I'm still just in RFC stage; wanting to make sure I have the
documentation correct for sample XML prior to actually coding
up the use of <glfs.h> from storage_backend_gluster.c.
Note that qemu's block/gluster.c documents that qemu expects
that when using glfs to bypass the file system, the image will
always be specified as:
* file=gluster[+transport]://[server[:port]]/volname/image[?socket=...]
which means that there is no way to pass a direct gluster volume
as a raw block device to qemu (it is always a file embedded within
the gluster volume); hence my choice of making a single gluster
volume act as the storage pool.

[libvirt] Using external ceph.conf for RBD pools and disks
by Michael Chapman
Hi all,
At the moment, RBD storage pools in libvirt must be supplied with a list
of Ceph monitor addresses, using <host> elements in the pool's source
definition. Ceph itself has a configuration file, and this is used by
default by all Ceph command-line utilities. This file can contain the
monitor addresses for the cluster, as well as a bunch of other useful
options (e.g. for tuning and debugging).
I think it would be nice if libvirt were able to load in this file when
starting RBD storage pools. Before I send some patches through. however, I
thought I'd better check to see whether my approach is sound.
First, I am not keen on having libvirt get librados to load the
configuration file automatically. librados actually uses a search path to
find the configuration file, and that path includes silly things like the
current working directory. Since it can be told to load a single file, I
think it would be better if it were made explicit in the storage pool XML,
i.e.:
<pool type="rbd">
<name>rbd</name>
<source>
<name>rbd</name>
<config file="/etc/ceph/ceph.conf"/>
<auth username="user" type="ceph">
<secret usage="mycephcluster"/>
</auth>
</source>
</pool>
<config> would be able to be used in addition to, or as an alternative to,
a list of <host> elements. Would something along these lines this be
suitable? Would it be better to use the <config> element's text content as
the filename, rather than use an attribute? I'm not sure what style
guidelines there are for something like this.
The second part is of course to make a similar change to RBD-based domain
disk definitions, i.e.:
...
<disk type="network">
<driver name="qemu" type="raw"/>
<source protocol="rbd" name="pool/volume">
<config file="/etc/ceph/ceph.conf"/>
</source>
<target dev="vda" bus="virtio"/>
<auth username="user">
<secret type="ceph" usage="mycephcluster"/>
</auth>
</disk>
...
Again, <config> could be used instead of or alongside some <host>
elements.
This is where it gets a little tricky. At the moment, <host> in a disk's
source definition is entirely optional. Furthermore, QEMU _always_ loads a
Ceph configuration file -- either one supplied as a "conf" argument for
the block device, or one found through the search path mentioned earlier.
The only way to suppress this is to pass conf=/dev/null... but for
backwards-compatibility (users may be relying on QEMU's use of the search
path), I don't think we can do this now.
There's one final gotcha in all of this: if QEMU is given both a "conf"
argument and a "mon_addr" argument, only the latter will take effect. This
means if both <config> and <host> are supplied, then the <host> elements
will override any monitor addresses from the configuration file.
For consistency, I intend to make an RBD storage pool have the same
behaviour. However, would it perhaps be better if the user could only
choose _either_ <config> or a list of <host> elements? Personally, I don't
think it's a big deal if the behaviour is clearly documented -- being able
to load options from a config file while still defining hosts in the
libvirt XML could be useful.
Anyway, before I send my patches through I'm interested in hearing
people's thoughts on this. All sound sane? Too intrusive? A waste of time?
:-)
