[Libvir] Patch: include <locale.h> for setlocale
by Richard W.M. Jones
Very trivial, but useful for me because I'm trying to debug the remote
stuff without -O, and without -O it turns out that libvirt doesn't compile.

[Libvir] [PATCH] parsing virsh options is wrong
by Saori Fukuta
Hi,
When I specified -t (or -q) option with virsh command, the result is
something wrong.
It is likely to be caused by the way to parse the virsh options.
(example)
I would like to know the node information with timing information.
So, I try some cases.
1) virsh with "-t nodeinfo"
ran virsh interactive terminal. Hmm, I didn't expect that...
# virsh -t nodeinfo
Welcome to virsh, the virtualization interactive terminal.
Type: 'help' for help with commands
'quit' to quit
virsh #
2) virsh with "-t aa nodeinfo"
I got the node information with timing information. But what does
"aa" option mean?? (Of course no meaning.)
# virsh -t aa nodeinfo
CPU model: i686
CPU(s): 2
CPU frequency: 1828 MHz
CPU socket(s): 1
Core(s) per socket: 2
Thread(s) per core: 1
NUMA cell(s): 1
Memory size: 1037312 kB
(Time: 2.821 ms)
3) virsh with "-t tt nodeinfo"
ran virsh interactive terminal. What's the difference with "aa"?
# virsh -t tt nodeinfo
Welcome to virsh, the virtualization interactive terminal.
Type: 'help' for help with commands
'quit' to quit
virsh #
I think the cause is missing a conditional before getopt_long at
vshParseArgv and add to check whether "o->has_arg" is 1 or not.
After the fix, I can use virsh options normally.
(example)
1) virsh with "-t nodeinfo"
# ./virsh -t nodeinfo
CPU model: i686
CPU(s): 2
CPU frequency: 1828 MHz
CPU socket(s): 1
Core(s) per socket: 2
Thread(s) per core: 1
NUMA cell(s): 1
Memory size: 1037312 kB
(Time: 2.626 ms)
2) virsh with "-t aa nodeinfo"
# ./virsh -t aa nodeinfo
error: unknown command: 'aa'
3) virsh with "-t tt nodeinfo"
# ./virsh -t tt nodeinfo
error: unknown command: 'tt'

[Libvir] Linker dependancoes [Re: [kvm-devel] QEMU / KVM support in libvirt & virt-manager]
by Daniel P. Berrange
See this thread on kvm-devel for a question about link time dependancies
in libvirt. I'm not sure what the optimal approach is for us to deal with
this is - just something we should think about in an idle moment...

[Libvir] Remote patch, 2007-02-26
by Richard W.M. Jones
I was really hoping to have a patch which could be applied out today.
This isn't quite that patch, so my apologies. Nevertheless, this
demonstrates what can be done, and works on a selection of the important
libvirt API calls.
http://www.annexia.org/tmp/libvirt-tls-20070226.patch
List of things that need to be done:
* Audit incoming IP addresses / virConnectOpen names to syslog.
* GnuTLS handshake DoS fix (see danpb's email).
* GnuTLS client crashing bug (I have a fix, just needs to be applied).
* Complete the wrappers for the remaining API calls.
* Testing(!)
Apart from that list above, I'm hoping that this patch addresses
everything that people have raised on list and privately about previous
patches. If I've missed anything, let me know.
Rich.

Re: [Libvir] [patch 3/3] Use libuuid to generate UUIDs

On the one hand I think its good to re-use existing libraries where
they fullfill our needs, but then we need to keep a built-in impl of
UUID generator for non-Linux systems which typically won't have a
e2fsprogs available. So rather than maintaining two separate impls
of the UUID code, which splits the testing coverage, I'd be inclined
to just always use the builtin version. Guarenteeing consistent
algorithm / semantics for UUID generation across all platforms.
