Hi Mark, Thanks very much! I have solved my problem by setting "allow-migrate=true" for my VM resource.and I find something for migration in pacemaker-explained: 9.3.4.1. Migration Checklist • The resource may not be a clone. • The resource must use an OCF style agent. • The resource must not be in a failed or degraded state. • The resource must not, directly or indirectly, depend on any primitive or group resources. • The resources must support two new actions: migrate_to and migrate_from and advertise them in its metadata. -->The resource must have the allow-migrate meta-attribute set to true (not the default). I am so careless :).Thanks for your help. I
