Xen devel - Jul 2008 - [PATCH] Fix destruction of VMMetrics objects for managed domains

While plugging a xend memory lead (c/s 18030), I introduced a bug in the 
case of managed domains.  Managed domains continue to exist after 
shutdown and thus should not have their associated VMMetrics object 
destroyed until deleted.

The bug actually manifested by a new -> start -> shutdown -> delete 
sequence of operations.  Shutdown destroyed the VMMetrics object and 
delete tried to do the same :-):

xen65:~/jim # xm del opensuse-10.3
Error: (''fa5160c0-bc7a-1459-974b-d3e023c717dd'',
''VM_metrics'')
Usage: xm delete <DomainName>

Initially, I was simply going to clean up exception handling but decided 
to go with the attached hack (*cough* ..., I mean patch) since users may 
be interested in VMMetrics even when the vm is powered-off.

Regards,
Jim
