I am using gentoo linux.

When I input, /etc/init.d/xend start, system replies

/etc/init.d/xend: /usr/sbin/xend: /usr/lib/portage/pym: bad interpreter: Permission denied

like Mihai said: please post the output of # head -n 5 /usr/sbin/xend In my gentoo-system this is: xen ~ # head -n 5 /usr/sbin/xend #!/usr/bin/python2.7 # -*- mode: python; -*- #============================================================================ # Copyright (C) 2004 Mike Wray <mike.wray@xxxxxx> # Copyright (C) 2005-2006 XenSource Inc So please also send the output of # ll /usr/bin/python* and # eselect python list # revdep-rebuild might fix the problem. I guess, you changed your python-version recently.
