Container Images
----------------
Container images, sometimes also referred to as ``templates'' or
``appliances'', are `tar` archives which contain everything to run a container.
-{pve} itself provides a variety of basic templates for the most common Linux
-distributions. They can be downloaded using the GUI or the `pveam` (short for
-{pve} Appliance Manager) command line utility.
-Additionally, https://www.turnkeylinux.org/[TurnKey Linux] container templates
-are also available to download.

The list of available templates is updated daily through the 'pve-daily-update'
timer. You can also trigger an update manually by executing:
`cpuunits`: :: This is a relative weight passed to the kernel scheduler. The
larger the number is, the more CPU time this container gets. Number is relative

+prioritize some containers.
[[pct_memory]]
NOTE: The bind mount source path must not contain any symlinks.
For example, to make the directory `/mnt/bindmounts/shared` accessible in the
-container with ID `100` under the path `/shared`, use a configuration line like
-`mp0: /mnt/bindmounts/shared,mp=/shared` in `/etc/pve/lxc/100.conf`.
-Alternatively, use `pct set 100 -mp0 /mnt/bindmounts/shared,mp=/shared` to

Device Mount Points

+ the `storage` parameter (default: `local`).

+Move a mount point volume to a different storage.

+Reassign a volume to a different CT. This will remove the volume `mp0` from
+the source CT and attaches it as `mp1` to the target CT. In the background
+the volume is being renamed so that the name matches the new owner.
