[CentOS] Redhat Virtualization

Dear Natarj,

AFAIK there is no difference at the hypervisor. They both use the same
hypervisor for virtualization (KVM). The key difference is that RHEV has two
part RHEV-H and RHEV-M. RHEV-H is a specialized RHEL product with kvm
hypervisor to run the guests. RHEV-M is the management interface for
managing RHEV-H nodes. AFAIK you can manage RHEL based systems too so there
shouldn't be too much difference beetween the systems. I think they use
libvirt for managing nodes so with CentOS you can use libvirt (with python
binding for example) as well to manage multiple nodes(there are some
projects what using it). I've found few months ago an article about the
RHEV-M that it will be open sourced (now it's closed and runs only on
windows).

http://www.linux-kvm.com/content/update-rhev-m-going-open-source

(I hope that when it will be open source it will be included in RHEL so we
can use it under CentOS, but i think that CentOS developers will include it
:) ).

If you want to have a good management interface, you have windows servers
where you can install it, and you can purchase it i suggest you to buy the
licenses because what i've seen from it it's very good. Easy to use, and
easier to manage multiple hypervisors (and there are lot other advantages).
If you don't need support, and the management interface, and you don't have
money to pay the subscription CentOS is a better choice (because you get the
same hypervisor).

I hope that this helped you a little and i haven't missed too much :).

Brgds,
Gabor
