Currently when spawning containers with systemd, the container PID 1
will get moved into the systemd machine slice. Libvirt then manually
moves the libvirt_lxc and qemu-nbd processes into the cgroups associated
with the slice, but skips the systemd controller cgroup. This means that
from systemd's POV, libvirt_lxc and qemu-nbd are still part of the
libvirtd.service unit.
On systemctl daemon-reload, it will notice that libvirt_lxc & qemu-nbd
are in the libvirtd.service unit for the systemd controller, but in the
machine cgroups for resources. Systemd will thus move them back into
the libvirtd.service resource cgroups next time libvirtd is restarted.
This causes libvirtd to kill off the container due to incorrect cgroup
placement.
The solution is to ensure that when moving libvirt_lxc & qemu-nbd, we
also move the systemd cgroup controller placement. Normally this is
not something we ever want todo, but this is a special case as we are
intentionally wanting to move them to a different systemd unit.

how have (almost[1]) 100% API coverage all the way to 2.5.0. They also
expose the APIs in a way that allows for much stronger go type
checking by the compiler, and expose typed parameters as explicit
structs. Finally the bindings are able to conditionally compile against
any libvirt version 1.2.0 -> 2.5.0 without use of go build tags.

We already have the ability to turn off dumping of guest
RAM via the domain XML. This is not particularly useful
though, as it is under control of the management application.
What is needed is a way for the sysadmin to turn off guest
RAM defaults globally, regardless of whether the mgmt app
provides its own way to set this in the domain XML.
So this adds a 'dump_guest_core' option in /etc/libvirt/qemu.conf
which defaults to false. ie guest RAM will never be included in
the QEMU core dumps by default. This default is different from
historical practice, but is considered to be more suitable as
a default because
a) guest RAM can be huge and so inflicts a DOS on the host
I/O subsystem when dumping core for QEMU crashes
b) guest RAM can contain alot of sensitive data belonging
to the VM owner. This should not generally be copied
around inside QEMU core dumps submitted to vendors for
debugging
c) guest RAM contents are rarely useful in diagnosing
QEMU crashes

The current LUKS support has a "luks" volume type which has
a "luks" encryption format.
This partially makes sense if you consider the QEMU shorthand
syntax only requires you to specify a format=luks, and it'll
automagically uses "raw" as the next level driver. QEMU will
however let you override the "raw" with any other driver it
supports (vmdk, qcow, rbd, iscsi, etc, etc)
IOW the intention though is that the "luks" encryption format
is applied to all disk formats (whether raw, qcow2, rbd, gluster
or whatever). As such it doesn't make much sense for libvirt
to say the volume type is "luks" - we should be saying that it
is a "raw" file, but with "luks" encryption applied.
IOW, when creating a storage volume we should use this XML
<volume>
<name>demo.raw</name>
<capacity>5368709120</capacity>
<target>
<format type='raw'/>
<encryption format='luks'>
<secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccd2f80d6f'/>
</encryption>
</target>
</volume>
and when configuring a guest disk we should use
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/home/berrange/VirtualMachines/demo.raw'/>
<target dev='sda' bus='scsi'/>
<encryption format='luks'>
<secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccd2f80d6f'/>
</encryption>
</disk>

util: Add 'luks' to the FileTypeInfo
The storage file probing code is modified so that it can probe
the actual encryption formats explicitly, rather than merely
probing existance of encryption and letting the storage driver
guess the format.
The rest of the code is then adapted to deal with
VIR_STORAGE_FILE_RAW w/ VIR_STORAGE_ENCRYPTION_FORMAT_LUKS
instead of just VIR_STORAGE_FILE_LUKS.
The commit mentioned above was included in libvirt v2.0.0.
So when querying volume XML this will be a change in behaviour
vs the 2.0.0 release - it'll report 'raw' instead of 'luks'
for the volume format, but still report 'luks' for encryption
format. I think this change is OK because the storage driver
did not include any support for creating volumes, nor starting
guets with luks volumes in v2.0.0 - that only since then.
Clearly if we change this we must do it before v2.1.0 though.

an arbitrary number of environment variables determined
by the SSH daemon and PAM configuration. Most of these are
not relevant inside the container, and at best they are
noise and at worst they'll break apps. For example if
XDG_RUNTIME_DIR is leaked to the container, it'll break
any apps using it, since the directory it points to is
only visible to the host OS filesystem, not the container
FS.
Use clearenv() to blank out everything and then set known
good values for PATH, SHELL, USER, LOGNAME HOME and TERM.
Everything else is left up to the login shell to initialize.

The virDomainFree / virConnectClose methods will reset the
last error handle, so we must save the error during cleanup
