Depending on what you're trying to do, the user-mode Linux port can really
be your friend.  See http://user-mode-linux.sourceforge.net.  It lets you
run an independent kernel in user mode, which brings a lot of nice things.
Crashes don't bring down the whole system.  You can use gdb on any process
in the user-mode "system."  And so on.  Good stuff.
