NAME

       uml_mkcow -- create a new COW file

SYNOPSIS

       uml_mkcow [-f]  [COW_file]  [backing_file]

DESCRIPTION

       This manual page documents briefly the uml_mkcow command.

       This  manual  page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.  Instead, it
       has documentation in HTML format; see below.

       uml_mkcow is a small utility to create COW (Copy-On-Write) files without the need to run the full UML kernel.

       NOTE: you can save a lot of disk space using COW files.	When checking the size of the COW file in order to see	the  gobs  of  space  that
       you're saving, make sure you use 'ls -ls' to see the actual disk consumption rather than the length of the file. The COW file is sparse, so
       the length will be very different from the disk usage.

OPTIONS

       -f	 Force overwrite of an exsiting COW file.

EXAMPLES

       Create a new COW file:

       uml_mkcow rootfs_COW rootfs

       Overwrite (destroying) an existing COW file:

       uml_mkcow -f rootfs_COW rootfs

NAME

       uml_switch -- switch daemon for user-mode Linux

SYNOPSIS

       uml_switch [-unix control_socket data_socket]  [-hub]  [-tap tun device]  [-compat-v0]  [-daemon]

DESCRIPTION

       This manual page documents briefly the uml_switch program.

       This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

       uml_switch is a daemon for managing a virtual network between user-mode Linux systems, with no connection to the host system's network.

       It will listen for connections on a pair of UNIX domain sockets, and forward packets between clients which connect to them.

OPTIONS

       -unix control_socket data_socket
                 Listen on the specified pair of sockets, instead of the defaults.

       -hub      Act  like  a hub.  This means that packets received will be broadcast over all virtual links.  The default is to act as a switch,
                 where packets are only sent to the link matching the destination MAC address of the packet.

       -tap tap device
                 Connect the switch to a dynamically created tap device on the host

       -compat-v0
                 Specify control protocol version 0 compatibility.

       -daemon   Run in the background as a daemon.
