uml_mconsole — attach to the management console of a user-mode Linux kernel

       uml_mconsole was written by Jeff Dike and others.

       This manual page was written by Matt Zimmerman mdz@debian.org for the DebianGNU/Linux system,  based  on
       material in the UserModeLinux-HOWTO by Rusty Russell, and the uml_mconsole source code.

                                                                                                 UML_MCONSOLE(1)

       version   Prints the UML version number.

       halt      Shuts  down  the  UML  system  immediately, without syncing disks or cleanly shutting down swap
                 space.

       reboot    Reboots the UML system immediately, without syncing disks or cleanly shutting down swap space.

       log string
                 Cause UML to log string to the kernel log.

       cad       Invokes the Control-Alt-Delete handler.

       sysrq letter
                 Performs the SysRq action controlled by letter.

       stop      Pauses UML.  UML will do nothing until the 'go' command is issued.

       go        Resumes execution after a 'stop' command.

       config device
                 Adds a new device to the virtual machine, or queries the configuration of an  existing  device.
                 It  takes  one  argument, which is either the device to add, with the same syntax as the kernel
                 command line, or the name of an existing device.  For example:

       (mconsole)
       configubd3=root_fs_debian22
       OK

       (mconsole)
       configubd3
       OK root_fs_debian22

       remove    Deletes a device from the virtual machine.  Its argument is  the  name  of  the  device  to  be
                 removed.   In the case of the ubd driver, the removed block device must not be mounted, swapped
                 on, or otherwise open, and in the case of the network driver, the device must be down.

       (mconsole)
       removeubd3
       OK

       This manual page documents briefly the uml_mconsole command.

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

       uml_mconsole is a program to connect to the management console of a  user-mode  Linux  kernel.   The  UML
       management  console is a low-level interface to the kernel, somewhat like the i386 SysRq interface. Since
       there is a full-blown operating system under UML, there is much greater flexibility  possible  than  with
       the SysRq mechanism.

socket    The pathname of the socket to which to connect.  This is printed when UML boots, for example:

       mconsole initialized on /tmp/umlNJ32yL/mconsole

                 In this example, you would start uml_mconsole like this:

       uml_mconsoleumlNJ32yLcommand   Any of the commands listed in the “COMMANDS” section.
