------- Comment #6 from jwest@xxxxxxxxxxxx  2007-12-14 10:38 -------
I *think* one can safely restart xend without affecting running VM's, as all of
the information xend maintains is in the xenstore and
/var/lib/xend/{domains,state}.  But, I believe init scripts in most linux
distributions will shutdown all VM's upon a xend restart, not realizing one can
restart xend w/o hurting those VM's.

I suppose another way is to just live migrate all VM's from one system to
another and then restart xend.
