Almost.  '&> word' and '>& word' on non-integer word are bash-isms
(actually, &> is preferred, because '>&$x' is ambiguous if you don't
know if x expands to an integer or a file name), and bash treats both as
shorthand for '> word 2>&1'.  Therefore, the correct replacement for
dash (or any other POSIX shell that doesn't understand bash's extension)
would be:

kill -0 $virsh_pid >/dev/null 2>&1 || break

At any rate, ACK with that squashed in, so I pushed it.
