[Xen-ia64-devel] Maybe doman_destroy() was not called?

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi all,

I tested xm create command with latest xen-ia64-unstable and the 
attached patch.  The attached patch intentionally causes contiguous 
memory shortage in VHPT allocation for HVM domain.  On the test, 
I wanted to confirm that the release proceeding of domain resources 
is working correctly when HVM domain creation failed.  But I could 
not confirm that it is working correctly.  It seemed to be not 
calling domain_destroy(). 
The following messages are the result of the test.  Different RID 
was allocated whenever I created a HVM domain. 
Do you think where a bug hides?
