b8b38321e7 caps: Add helpers to convert NUMA nodes to corresponding CPUs
These helpers use the remembered host capabilities to retrieve the cpu
map rather than query the host again. The intended usage for this
helpers is to fix automatic NUMA placement with strict memory alloc. The
code doing the prepare needs to pin the emulator process only to cpus
belonging to a subset of NUMA nodes of the host.

b904bba7f4 Add a policy kit access control driver
Add an access control driver that uses the pkcheck command
to check authorization requests. This is fairly inefficient,
particularly for cases where an API returns a list of objects
and needs to check permission for each object.

It would be desirable to use the polkit API but this links
to glib with abort-on-OOM behaviour, so can't be used. The
other alternative is to speak to dbus directly

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.

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.

c57e3d8994 Introduce basic infrastructure for virtlockd daemon
The virtlockd daemon will maintain locks on behalf of libvirtd.
There are two reasons for it to be separate

 - Avoid risk of other libvirtd threads accidentally
   releasing fcntl() locks by opening + closing a file
   that is locked
 - Ensure locks can be preserved across libvirtd restarts.
   virtlockd will need to be able to re-exec itself while
   maintaining locks. This is simpler to achieve if its
   sole job is maintaining locks

60f0f55ee4 Add iSCSI backend storage driver for ESX
The patch adds the backend driver to support iSCSI format storage pools
and volumes for ESX host. The mapping of ESX iSCSI specifics to Libvirt
is as follows:

1. ESX static iSCSI target <------> Libvirt Storage Pools
2. ESX iSCSI LUNs          <------> Libvirt Storage Volumes.

The above understanding is based on http://libvirt.org/storage.html.

The operation supported on iSCSI pools includes:

1. List storage pools & volumes.
2. Get XML descriptor operaion on pools & volumes.
3. Lookup operation on pools & volumes by name, UUID and path (if applicable).

iSCSI pools does not support operations such as: Create / remove pools
and volumes.
