Please take a look at calculation in 

http://www.ovirt.org/Automatic_Fencing#Automatic_Fencing

Host status will to Non Responding if either number of unsuccessful
connection attempts exceeds VDSAttemptsToResetCount or timeout from
last successful connection is expired.

To alter time for host to be fence you can change these values from above
mentioned calculation can be changed using engine-config tool:

  VDSAttemptsToResetCount
  TimeoutToResetVdsInSeconds
  DelayResetPerVmInSeconds
  DelayResetForSpmInSeconds


Is there any specific issue for which you need to change those values?
