[libvirt] [PATCH] qemu: Avoid dereference of NULL pointer
by Peter Krempa
If something fails while initializing qemu job object in
qemuDomainObjPrivateAlloc(), memory to the private pointer is freed, but
after that, the pointer is still dereferenced, which may result in a
segfault.
* qemuDomainObjPrivateAlloc() - Don't dereference NULL pointer.
---
I added the label and jump with future expansions in mind, as I've
found this bug while modifying said function.

[libvirt] libvirt-gconfig patches
by Christophe Fergeau
Here is the 3rd version of my libvirt-gconfig patches, I did the renaming
to put all the new classes it introduces in the GVirConfigDomain namespace.
GVirConfigDomainSnapshot looks a bit out of place now though...
Apart from this, I fixed the other issues that were reported, and
rearranged a bit the patches introducing GVirConfigDomainInterfaceNetwork.
I've also pushed the first 5 patches that were in v2 since they've already
been ack'ed

[libvirt] [PATCH] qemu: fix a const-correctness issue
by Eric Blake
Generally, functions which return malloc'd strings should be typed
as 'char *', not 'const char *', to make it obvious that the caller
is responsible to free things. free(const char *) fails to compile,
and although we have a cast embedded in VIR_FREE to work around poor
code that frees const char *, it's better to not rely on that hack.
* src/qemu/qemu_driver.c (qemuDiskPathToAlias): Change return type.
(qemuDomainBlockJobImpl): Update callers.
