UML_MCONSOLE(1) General Commands Manual UML_MCONSOLE(1) NAME
uml_mconsole -- attach to the management console of a user-mode Linux kernel SYNOPSIS
uml_mconsole [socket] [command ...] DESCRIPTION
This manual page documents briefly the uml_mconsole command. This manual page was written for the Debian GNU/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. OPTIONS
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_mconsole umlNJ32yL command Any of the commands listed in the "COMMANDS" section. COMMANDS
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) config ubd3=root_fs_debian22 OK (mconsole) config ubd3 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) remove ubd3 OK SEE ALSO

pbuilder-user-mode-linux(1) pbuilder pbuilder-user-mode-linux(1) NAME
pbuilder-user-mode-linux - personal package builder in UML SYNOPSIS
pbuilder-user-mode-linux create [options] pbuilder-user-mode-linux update [options] pbuilder-user-mode-linux build [options] .dsc-file pbuilder-user-mode-linux execute [options] script pbuilder-user-mode-linux login [options] DESCRIPTION
Front end program to the pbuilder suite of programs, used for creating and maintaining user-mode-linux environment and building Debian package within the user-mode-linux virtual machine environment. Unlike pbuilder , pbuilder-user-mode-linux does not require root privilege to run. It should be ran under a normal user. OPTIONS
create Creates a user-mode-linux root image for the specified distribution using rootstrap software update Updates the user-mode-linux root image for the specified distribution. Also, by specifying the --distribution option, it is possi- ble to switch the distribution. Specify a dummy distribution value even for custom apt config files. build Builds the package specified by .dsc-file within the user-mode-linux environment. login Invokes shell within UML. dumpconfig dumps configuration information about user-mode-linux, used for debugging. execute Invokes a command or script inside UML. execute will copy the specified file into the UML system, and run it. The remaining command-line arguments are passed on to the script. --uml-image [UML image] Specify the UML image to use. --eth0 [uml option for eth0] Specify this option as parameter to UML. Specify --eth0=slirp,12345,/usr/bin/slirp-fullbolt to use the slirp connection. --uml-ip [IP inside UML] Specify this to set the IP inside UML. This can be set to dhcp for obtaining IP address through DHCP. --uml-netmask [netmask] The netmask. --uml-network [network] The network address. --uml-broadcast [broadcast] The broadcast address. --uml-gateway [gateway] The gateway address. --mount-tmpfs [yes] Specify whether to mount tmpfs inside UML chroot. --uml-hostname [uml-host] The hostname inside uml. --distribution [sid] Specify the distribution. see pbuilder(8) --binary-arch Specify only to build binary-arch targets. see pbuilder(8) --timeout timeouttime Timeout build after specified time. see pbuilder(8) --configfile config file to read Makes pbuilder to read the config file inside UML. pbuilder-user-mode-linux itself would be affected by the contents of the config file. --hookdir location of hooks Makes pbuilder use the specified hookdir inside UML. --aptconfdir apt configuretion directory Makes pbuilder to use specified apt configuration directory instead of other settings. See pbuilder(8) --override-config Specify this option along with --distribution to switch distribution using pbuilder-user-mode-linux update --logfile logfilename Specify this option to make the output go to logfilename as well as standard output. --buildresult /dir/to/build/result The directory where build result is placed to --uml-debugmode Enable tracing of shell scripts used by pbuilder-user-mode-linux. --bindmounts /dir/to/bind-mount Bind-mount the directory inside the chroot inside the user-mode-linux. --buildplace place-to-put-COW-file Specify the directory to place the COW file. The user needs to be able to access that directory, and the directory must exist. --uml-login-nocow Do not use COW filesystem when using pbuilder-user-mode-linux login so that changes made in the log in session will persist. Effective in login and exec options. --mirror [mirror location] Specifies the URL of Debian mirror to be specified in sources.list inside the chroot. This option is only valid when distribution is being specified, for update and build targets. The format is something like: http://http.us.debian.org/debian which should point to your favourite mirror. This option can optionally be omitted, and left blank, in which case, this part is skipped. Note that these URLs specified to pbuilder will be used from within the chroot, and specifying file:/somewhere/ will most probably fail. --othermirror [deb http://xxx/xxx/ ./ | other deb lines... ] The lines which is added to the sources.list, delimited with | Like deb http://local/mirror stable main|deb file:/usr/local/mirror ./ The deb lines here are the ones that will appear at the top of the sources.list inside the chroot. Be sure to follow the syntax rules of sources.list(5). These lines appear at the beginning of the constructed sources file, so this is the place to list your local mirror sites; apt will then use them in preference to the ones listed in --mirror . These options are only valid when --override-config option is specified in update target, or when pbuilder create is being called. NOTES
For build and login targets, pbuilder-user-mode-linux will try to use COW devices. Inside user-mode-linux, pbuilder-user-mode-linux will mount tmpfs as /tmp to avoid temporary file race conditions with outside of UML. This may cause problems trying to use files in /tmp directory. FILES
/etc/pbuilderrc The system-wide configuration file for pbuilder. /usr/share/pbuilder/pbuilderrc The default settings for pbuilder, used as fallback for all values that is not specified in /etc/pbuilderrc. /etc/pbuilder/pbuilder-uml.conf System-wide configuration file for pbuilder-uml, it will take priority over pbuilder configurations. /usr/share/pbuilder/pbuilder-uml.conf Software-default configuration file for pbuilder-uml. ${HOME}/.pbuilderrc User-default configuration file.
