  1. From your crm status output, all the resources defined in the group IPFailover should be running on testsrvm1.test-domain.biz, as indicated by the last two lines.

    For which alternative machine it may run the resources on, it should usually run the resources in all nodes in that cluster, which is the two nodes on the line begin with "Online:". However, if crm config have some location rule to prevent it from running on some node, it won't run on that.
