This is true... this is my ''second'' PVE experiment, the first are
using a SAN via iSCSI, and i've also ''fine tuned'' the shutdown times
in UPSes...

I doubt that. Probably, as shutdown have to be tuned, startup have too,
as Eneko said.

I'm used to set ''random boot delay'' on my servers, to prevent spikes
on UPSes.
Probably i've only to force some predictable startup time...


Thanks to all!
