[libvirt] [PATCH 1/4] lxc: validate tty pid before kill()

[Dave Leskovec]

This patch adds a check of the tty forwarding process pid before kill()'ing it
when destroying a domain.  If the pid value stored in the the vm structure is
invalid, sending a SIGKILL may be very bad if the value in question is something
like -1 (which just happens to be it's initial value).
