Hi. As many here - I am total newbie to OpenStack(while have some experience with commercial (AWS) cloud, Virtual box Vagrant and so on) What I am trying to figure out is - can we migrate part of our ESX clusters to OpenStack... Main reasons :

  1. switch to DevOps work mode (automatic deployment of Vms by developers without involvement of IT)
  2. Cut expanses (VMware licences for Vsphere and other commercial components)

So - question is - if it is feasible. I suppose DevOps mode with OpenStack + Vsphere integration is feasible , but it means - we will have to continue to pay for VmWare licences... What I can not understand - is it feasible to run OpenStack on ESX hardware without Vsphere - basing only of free esxi component on "backhand" of OpenStack?

vmware has Seriously discouraged development in this area because it encroaches into some of their "secret sauce" and breaks the need for vsphere (licensing services in general) and is against their business intention. They do have the ability to integrate VERY easily with multiple vsphere controllers however.

if you just want to get around vcenter you are going to have to give up on vmware and go with a different hypervisor such as xen or kvm.

Can I run them (xen or kvm) over blades , designed for VmWare? I mean - quite surely , since at the end those blades have x86 type processors - I should be able to run those hypervisors.. But - will not it cause drastic derogation of performance , compared to run of ESXi hypervisor over them?

absolutely yes. follow the install guide and run centos7. performance degredation??? Amazon and Rackspace run xen. i would try it before you worry about preformance. once you get into understanding it you can run multiple hypervisors (like xen and kvm) if you wish.

Thanks guys. I think - it quite answer my question. Now I have to figure out - how practically to do it (perform such test installation), but that is another story...
