A deeper look at Google Ganeti

In the past few days, I got a deeper look in google ganeti, and asked many questions on their google group.

First, I got the impression that some things are not well working and lead to deadlocks and situations where you cannot start virtual instances anymore.

But it turned out to be all a matter of using the gnt-instance activate-disks command at the right place, using --force with the gnt-instance startup command, and --ignore-consistency when doing a failover...

Apart from a little bit ugly messages, Ganeti is really a nicely workoing management thing - even if I have not yet tested everything it can do for us.

My testing report in German is in our xen wiki.
