e7976ea2f4 docs: Document libxl.conf location
This is similar to my earlier commit which documented lxc.conf
location. Just like LXC, the libxl driver has only the system
connection and thus only few places need changing.

fd2bd98852 manpages: Remove reference to a session daemon for libxl
The libxl driver has no session daemon therefore its split daemon
(virtxend) has to be ran as root. Any attempt to start it with
euid != 0 fails. This is why the daemon does not look under any
of XDG_* paths either.

4719ec15e9 qemu: add per-vcpu delay stats
This patch adds delay time (steal time inside guest) to libvirt
domain per-vcpu stats. Delay time is an important performance metric.
It is a consequence of the overloaded CPU. Knowledge of the delay
time of a virtual machine helps to understand if it is affected and
estimate the impact.

As a result, it is possible to react exactly when needed and
rebalance the load between hosts. This is used by cloud providers
to provide quality of service, especially when the CPU is
oversubscribed.

It's more convenient to work with this metric in a context of a
libvirt domain. Any monitoring software may use this information.

1d9d9961ad vircgroup: enforce range limit for cpu.shares
Before the conversion to using systemd DBus API to set the cpu.shares
there was some magic conversion done by kernel which was documented in
virsh manpage as well. Now systemd errors out if the value is out of
range.

Since we enforce the range for other cpu cgroup attributes 'quota' and
'period' it makes sense to do the same for 'shares' as well.
