7c12055def libvirt-guests: newline between output sentences
Right now, libvirt-guests gives awkward output.  It's possible to
force faster failure by setting /etc/sysconfig/libvirt-guests to use:

ON_SHUTDOWN=shutdown
PARALLEL_SHUTDOWN=0
SHUTDOWN_TIMEOUT=1
ON_BOOT=ignore

at which point, we see:

$ service libvirt-guests restart
Running guests on default URI: a, b, d, c
Shutting down guests on default URI...
Starting shutdown on guest: a
Shutdown of guest a failed to complete in time.Starting shutdown on guest: b
Shutdown of guest b failed to complete in time.Starting shutdown on guest: d
Shutdown of guest d failed to complete in time.Starting shutdown on guest: c
Shutdown of guest c failed to complete in time.libvirt-guests is configured not to start any guests on boot

* tools/libvirt-guests.sh.in (shutdown_guest): Add missing newline.

b88831f751 virsh: Fix docs for "virsh setmaxmem"
The docs assumed the command works always for QEMU and other
hypervisors. As this is done using the balloon mechainism live increase
of the maximum memory limit isn't supported. Fix the docs to mention
this limitation.

Don't print the pool option name if it's null.

Before:
virsh # vol-name vol

error: Storage volume not found: no storage vol with matching path vol

After:

virsh # vol-name vol
error: failed to get vol 'vol'

7e437ee78f virsh: Introduce macros to reject mutually exclusive arguments
This patch adds three macros to the virsh source tree that help to
easily check for mutually exclusive parameters.

VSH_EXCLUSIVE_OPTIONS_EXPR has four arguments, two expressions to check
and two names of the parameters to print in the message.

VSH_EXCLUSIVE_OPTIONS is more specific and check the command structure
for the parameters using vshCommandOptBool.

VSH_EXCLUSIVE_OPTIONS_VAR is meant to check boolean variables with the
same name as the parameters.

2e1cd8900f clarify virsh net commands
Clarify that net-create deals with a transient virtual
network whereas net-define defines a persistent virtual
network definition and will create the network (xml)
definition file.

Clarify that net-destroy works with both transient and
persistent virtual networks.

73cc87d161 Cleanup useless flags specifications
After we switched to C99 initialization, I noticed there were many
places where the specification of .flags parameter differed.  After
going through many options and deciding whether to unify the
initialization to be '.flags = 0' or '.flags = VSH_OFLAG_NONE', I
realized both can be removed and it makes the code easier to go
through.

66f1bbc350 Fix snapshot-create-as syntax in help output
According to the man page, the memspec parameter should have the
'--memspec' option mandatory and this is as close as we can get to
that.  What this change does is explained below.

man virsh:

snapshot-create-as ... [[--live] [--memspec memspec]]

virsh help snapshot-create-as before this patch:

  SYNOPSIS
    snapshot-create-as ... [<memspec>] ...
...
  OPTIONS
    [--memspec] <string> ...

virsh help snapshot-create-as after this patch:

  SYNOPSIS
    snapshot-create-as ... [--memspec <string>] ...
...
  OPTIONS
    --memspec <string> ...

e4e69e899e Apply security label when entering LXC namespaces
Add a new virDomainLxcEnterSecurityLabel() function as a
counterpart to virDomainLxcEnterNamespaces(), which can
change the current calling process to have a new security
context. This call runs client side, not in libvirtd
so we can't use the security driver infrastructure.

When entering a namespace, the process spawned from virsh
will default to running with the security label of virsh.
The actual desired behaviour is to run with the security
label of the container most of the time. So this changes
virsh lxc-enter-namespace command to invoke the
virDomainLxcEnterSecurityLabel method.

The current behaviour is:

LABEL                             PID TTY          TIME CMD
system_u:system_r:svirt_lxc_net_t:s0:c0.c1023 1 pts/0 00:00:00 systemd
system_u:system_r:svirt_lxc_net_t:s0:c0.c1023 3 pts/1 00:00:00 sh
system_u:system_r:svirt_lxc_net_t:s0:c0.c1023 24 ? 00:00:00 systemd-journal
system_u:system_r:svirt_lxc_net_t:s0:c0.c1023 29 ? 00:00:00 dhclient
staff_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 47 ? 00:00:00 ps

Note the ps command is running as unconfined_t,  After this patch,

The new behaviour is this:

virsh -c lxc:/// lxc-enter-namespace dan -- /bin/ps -eZ
LABEL                             PID TTY          TIME CMD
system_u:system_r:svirt_lxc_net_t:s0:c0.c1023 1 pts/0 00:00:00 systemd
system_u:system_r:svirt_lxc_net_t:s0:c0.c1023 3 pts/1 00:00:00 sh
system_u:system_r:svirt_lxc_net_t:s0:c0.c1023 24 ? 00:00:00 systemd-journal
system_u:system_r:svirt_lxc_net_t:s0:c0.c1023 32 ? 00:00:00 dhclient
system_u:system_r:svirt_lxc_net_t:s0:c0.c1023 38 ? 00:00:00 ps

The '--noseclabel' flag can be used to skip security labelling.
