[ovirt-users] Decrease downtime for HA

[Daniel Menzel]

Hi Michael,
thanks for your mail. Sorry, I forgot to write that. Yes, we have power 
management and fencing enabled on all hosts. We also tested this and 
found out that it works perfectly. So this cannot be the reason I guess.

What we're dealing with at the moment is the high availability: If a node fails (for example simulated by a forced power loss) the engine comes back up online withing ~2min. But guests (having the HA option enabled) come back online only after a very long grace time of ~5min. As we have a reliable network (40 GbE) and reliable servers I think that the default grace times are way too high for us - is there any possibility to change those values?
