[Xen-users] DomU boot hangs after cron; XENBUS errors

["Tom Davis" <binjured@xxxxxxxxx>]

I am having an issue getting a DomU to boot properly.  There is never any indication of a stop error or kernel panic, it simply hangs after "Starting crond [ OK ]" and never continues.  I've included my mkinitrd and output from xm create... please help!
