hi All,

We are planning to build a private cloud for our department at academic institution. We are a born-in public-cloud institution.  Idea is to have a hybrid cloud.

Few important requirements:

* No vendor lock-in of hardware and software/distribution.

* Preferably stable software from  openstack.org.

* Also need to support Accelerated instances (GPU,FPGA,Other PCIecard).

* On standard rack servers with remote systems management for the nodes (IPMI based)

* Need to support Instances  [VMs (Qemu-KVM), Containers (Docker, LXC), Bare metal (Ubuntu)].

* Workload will be Software Development/Test (on VMs) and Benchmarking (on baremetal/container).

* Smooth upgrades.

Could anyone suggest stable Openstack installer for our multi-node setup (initially 40 physical machines, later around 80)? Upgrades should be smooth.

Any pointers to reference architecture will also be helpful.

PS: I have tried devstack recently. It works. Kolla fails. I tried packstack few years back.

Maruthi Inukonda.
