1) Misspelled message 'killing umanaged domain' (must be killing
UNmanaged domain)

2) more serious. I found this message after disappearance of virtual
machine created early. I restart XAPI tool stack and machine was killed
(not shutdowned, but completely removing). Here log (from machine where
domain was resident) 

Main line in log file I suspect:
