[libvirt] [PATCH] v2: Fix uninitialized variable & error reporting in LXC veth setup
by Daniel P. Berrange
THe veth setup in LXC had a couple of flaws, first brInit did
not report any error when it failed. Second vethCreate() did
not correctly initialize the variable containing the return
code, so could report failure even when it succeeded.

[libvirt] [PATCH] udev: fix regression with qemu:///session
by Eric Blake
https://bugzilla.redhat.com/show_bug.cgi?id=684655 points out
a regression introduced in commit 2215050edd - non-root users
can't connect to qemu:///session because libvirtd dies when
it can't use pciaccess initialization.
* src/node_device/node_device_udev.c (udevDeviceMonitorStartup):
Don't abort udev driver (and libvirtd overall) if non-root user
can't use pciaccess.

[libvirt] [PATCH] do not report OOM error when prepareCall() failed
by Wen Congyang
We have reported error in the function prepareCall(), and
the error is not only OOM error. So we should not report
OOM error in the function call() when prepareCall() failed.

[libvirt] [RFC PATCH 0/2] virObject for reference-counting
by Hu Tao
virObject is a base struct that manages reference-counting. structs
that need the ability of reference-counting can inherit from
virObject and implement ref/unref interface easily.
The goal of this series is to make reference-counting easy to use,
and improve the current libvir reference-counting mechanism. The
plan is to update all existing structs that use reference-counting
to use virObject if virObject is acceptable.
Patch 1 implements virObject, patch 2 is an illstration of usage of
…
[View More]virObject. This series is in draft stage, any comments are welcome.
Hu Tao (2):
Add virObject.

[libvirt] Question about virConnectDomainXMLToNative
by Michal Novotny
Hi,
I've been investigating the virConnectDomainXMLToNative() format option
and I found out the virConnectDomainXMLToNative() calls the
conn->driver->domainXMLToNative() function and passes the format to the
driver function where the check whether format is valid or not is being
performed. Unfortunately I was unable to get the list of supported
format strings (like "qemu-argv"/"xen-xm"/"xen-sexpr" etc.) so I'd like
to ask whether there is some API to get all the formats supported by …
[View More]the
driver or not.
If not, wouldn't it be worth it to add some API like
virConnectGetDomainNativeFormats() or something to return the format
option for the connection?
I guess many people would be having issues with that and although it's
documented in the virsh man pages what if somebody will be using some
other application than virsh or you add some formatting option however
you forget to add it to the man page?
I think it's worth it to consider adding
conn->driver->domainNativeFormats() to the driver and placing it nearby
the conn->driver->domainXMLToNative() function in the driver (like right
above qemuDomainXMLToNative() etc.).
Or is there some API way to get the domain format strings that I'm not
aware of, i.e. that I didn't find by my investigation?
Thanks,
Michal
