OpenStack support following hypervisor

https://docs.openstack.org/mitaka/config-reference/compute/hypervisors.html (https://docs.openstack.org/mitaka/con...)

but out of all hypervisor which hypervisor support shared resources I want it for development.

In KVM, it keeps resources reserved till you terminate the instance. I want to share the resources so I can run multiple instances without any problem.

I would say that all hypervisors allow you to run several instances. What resources do you have problems with?

because of hardware limitation. I have core i5 with 4 core cannot start more than 4 instances on OpenStack. I want to start more than 5 instances like as shared resources.

KVM does that, and as far as I know, so do all other hypervisors. I run 2 or more instances on a single-core node.

My guess is that there are other limitations that prevent you from starting more than 4 instances, such as RAM or storage.

Thanks, Bernd Bausch. I will check in my local lab.
