RUMP.HALT(1)						    BSD General Commands Manual 					      RUMP.HALT(1)

NAME

     rump.halt -- halt a rump kernel

SYNOPSIS

     rump.halt [-dhn]

DESCRIPTION

     The rump.halt utility exits a rump kernel.  The file system cache, if present, is flushed.  Since a rump kernel does not control its clients,
     they are not directly affected by rump.halt.  However, they will be unable to request further services from the halted rump kernel.

     The options are as follows:

     -d      Create a core dump.  The core file is saved according to standard userland program coredump rules, and can be later examined with a
	     debugger.

     -h      By default the process hosting the rump kernel exits.  Using this option shuts down rump kernel activity, but does not cause the
	     hosting process to exit.

     -n      Do not flush the file system cache.  This option should be used with extreme caution.  It can be used if a virtual disk or a virtual
	     processor is virtually on fire.

HISTORY

     The rump.halt command appeared in NetBSD 6.0.

CAVEATS

     While using -h makes it impossible to issue further system calls, it does not necessarily stop all activity in a rump kernel.  It is recom-
     mended this option is used only for debugging purposes.
