Hard to help. First of all, I would recommend to ask SUSE support 
because I don't really have access to source code of corosync 
1.4.7-0.23.5 package, so really don't know what patches are added.

^^^ This is important line. It means corosync was unable to find 
interface for bindnetaddr 192.168.150.0. Make sure interface with this 
network address exists.
