I made these changes but this leads to another issue.
When using the event handler to cleanup the domain
there seems to be a race condition.
The call to libxl_event_get_domain_death_info returns a value != 1
sometimes and the domain gets not cleaned up.
The latest version of the patch I posted in this thread earlier does
not have this issue as it cleans up the domain directly.
Maybe the every now and then fail of libxl_event_get_domain_death_info
is a result of a bug or unhandled race condition in Xen.
Cheers,
Markus
