[Xen-devel] [PATCH] Fix domain suspend by xend stop

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

When I stopped xend by xend stop command, a domain suspend processing 
is frequently failed.  This patch solves the problem.

Step to reproduce:
 1. xm new XXX on_xend_stop="suspend" 
 2. xm start XXX
 3. xend stop

In the xend stop, if the domain suspend processing is slept by 
state_updated.wait() of waitForShutdown(), then the domain suspend 
processing is not waked up again because state_updated.notifyAll() 
of _stateSet() is not executed. 

For the reason, processing of _on_domains_changed() is waited by 
domains_lock.acquire() because the domain suspend processing is 
keeping domains_lock and sleeping.  The domain suspend processing 
got domains_lock at cleanup_domains().

Best regards,
 Kan
