Description of problem: Various xend services may not survive "service xend restart": > > A xend restart is already broken in many ways - i don;t think we should > > support it unless all guests are shutdown. eg, tapdisk processes don't > > get cleaned up (resulting zombie guest upon shutdown), qemu-dm processes > > don't get cleaned up (more zombies), xen-vncfb didn't used to get cleaned > > up, but i think new pvfb makes them auto exit now avoiding zombies. > > Generally its all very fragile for restarts Ideally everything spawned by Xen should automatically detect when its corresponding domain has shutdown & exit itself. This involves some kind of crazy xenstore/xenbus watch setup which its totally confusing to me. So, yes, if anything has any clue how to make this work, it'd be good.
