*vws* - manage Virtual Workstations

SYNOPSIS
========

**vws create** *name* [ **--install** *isoimage* ]

**vws list**  \[**--state**\] \[**--usb**\] \[ *pattern* ... \]

**vws start** *name* [**--no-gui**] \[**--cdrom** *iso-image*\]

**vws stop** *name* [**--hard**]

**vws save** *name*

interaction with it.

**vws spiceuri** *machine*

Prints out URI you should feed into your spice viewer to access this
machine.

**vws list** [ **--state** ] \[ **--usb** \] \[ *pattern* .. \]

Lists available virtual machines. If **--state** option is given, prints
out state (running or stopped) type (private or shared) spice URI (if
machine is running), mac and IP address. Pattern is shell-style wildcard 
which limits machines to be shown. Don't forget to quote pattern from shell. It
should be expanded. **--usb** option lists USB devices connected to the
virtual machine using **vws usb** command.

**vws sendkey** *machine* *keyspec*

Allows to send some key combination to the virtual machine. For example
if windows screen is locked spice client is sometimes unable to deliver
key stroke to the virtual machine in order to get it out of sleep.
