Good day.

Few weeks ago we met an hang in our storage system and reboot all hosts
in affected pool. 

During 'whole pool boot' I found XCP is pretty slow on pool recovery -
it starts VM one-by-one.

It takes a lots of time. I thought, can we starts VM in parallel one-on
every host (one VM at time at every available host in the pool)? This
will speedup startup process significantly....
