010065d702 spec: Explicitly claim ownership of channel subdir
As both /var/lib/libvirt/qemu and /var/lib/libvirt/qemu/channel/target
are owned by us, the intermediate /var/lib/libvirt/qemu/channel should
be owned by us too.

1166eeba61 Fix crashing upgrading from older libvirts with running guests
If upgrading from a libvirt that is older than 1.0.5, we can
not assume that vm->def->resource is non-NULL. This bogus
assumption caused libvirtd to crash

b4ca299902 Avoid crash if NULL is passed for filename/funcname in logging
The journald code would crash if a NULL was passed for the
filename / funcname in the logging code. This shouldn't
happen in general, but it is better to be safe, since there
have been bugs triggering this.

cb3868f701 Ensure LXC/QEMU APIs set the filename for errors
The virLibConnError macros in libvirt-lxc.c and
libvirt-qemu.c were passing NULL for the filename.
This causes a crash if the logging code is configured
to use journald.

When building libvirt with -O0 flag in fedora 19, it will fail to
generate qemuagenttest, a link error occurs like:

./.libs/libqemumonitortestutils.a(qemumonitortestutils.o): In function `qemuMonitorTestFree':

75304eaa1a Cope with races while killing processes

while we're still doing virCgroupKillPainfully. We must

aedd46e7e3 Add support for systemd cgroup mount
Systemd uses a named cgroup mount for tracking processes. Add
it as another type of controller, albeit one which we have to
special case in a number of places. In particular we must
never create/delete directories there, nor add tasks. Essentially
the systemd mount is to be considered read-only for libvirt.

With this change both the virCgroupDetectPlacement and
virCgroupCopyPlacement methods must be invoked. The copy
placement method will copy setup for resource controllers
only. The detect placement method will probe for any
named controllers, or resource controllers not already
setup.
