I’m experimenting with OpenStack and OpenDaylight for 4 weeks now, and managed to crash the whole installation 4 times, when enabling OpenDaylight.

It’s really frustrating having to re-setup everything over and over again, even manually, so I decided to invest more time in setup automation via JuJu and freeze some snapshots before doing any further experiments.
But even automated setups keep hanging here and there and cost a lot of time.
Plus MaaS needs to be patched each time to be able to Wake On LAN my VM’s within Virtualbox.

Real hardware would be much easier, although I need at least 8 hosts with dual network cards, that’s out of reach for me at the moment.
My wife already complains about splashing VM windows on her iMac 😀
