*pct* `<COMMAND> [ARGS] [OPTIONS]`

*pct config* `<vmid>`

Get container configuration.

`<vmid>` `integer (1 - N)` ::

The (unique) ID of the VM.




*pct console* `<vmid>`

`<vmid>` `integer (1 - N)` ::

The (unique) ID of the VM.




*pct create* `<vmid> <ostemplate>` `[OPTIONS]`

`-cmode` `(console | shell | tty)` (default=`tty`)::

Console mode. By default, the console command tries to open a connection to

attach to /dev/console instead. If you set cmode to 'shell', it simply
invokes a shell inside the container (no login).

CPU time. Value '0' indicates no CPU limit.

`-cpuunits` `integer (0 - 500000)` (default=`1024`)::
