Subject cs 4.2 HA
Date Tue, 10 Sep 2013 17:04:08 GMT
Hi all.

I'm testing HA and when I power down one node, VM with ha offering enabled
does not start on other node.

env used:
management + 2 hypervisors + nfs server
management/hypervisors: CentOS 6.4 + CS-4.2(revision 2852) + advanced zone
+ KVM

I have the following nullpointerexception in logs:
