I think I've found the cause. If the hostname in 
/etc/vserver/<guestname>/name isn't the same as <guestname>, this 
happens. I would suggest this is a bug because guest name and the 
hostname of the guest don't have to be the same. vserver-stat should be 
referring to guests by guest name not by the hostname in 
/etc/vserver/<guestname>/name.
