High Availability tuning in RHEV beta 3

Hi, I've been testing RHEV beta3 and tried to test HA functionality . In order to proceed with that I simulated host (RHEL 6.1 ) to be non-responsive by switching rhevm and logical interfaces : #ifdown rhevm #ifdown rhev_lab Question: It took4 minutes till the host was set in non-responsive mode ! Is it possible to make some tuning in oreder the RHEV manager will react more faster ?
