Let's summarize again, SSH Soft Fencing patches has been merged yesterday with following functionality:
1) For hosts with power management configured, SSH Soft Fencing is the 1st fencing stage. If it doesn't help, real fencing will be executed.
2) For hosts without power management configured, SSH Soft Fencing is the only fencing stage. If it doesn't help, host will become non responsive.
3) SSH Soft Fencing is enabled by default, there's no configuration option to disable it
4) SshSoftFencingCommand option is used to define what command is executed during SSH Soft Fencing. It can only be changed manually in database.
The whole fencing process in oVirt 3.3 is decribed at

I assume ssh soft fencing isn't considered "fencing"? i.e., i assume it does not release resource occupied by the host (spm, running vms)? Thanks, Itamar
