Open Stack

We had a small deployment (2 nodes) of OS Juno+XS6.5 and after I understood how it should work with Xen everything worked great.
Still, we had to move for KVM because XS with local storage lacked support of dynamic volumes via Cinder.

If you plan to use shared storage for VMs, XS is a great choice. It’s MUCH easier to maintain then KVM, especially for a newbie in such technologies

Subject: Re: [Openstack] XenServer 6.5 or KVM

Thank you guys.
One last question: This 3 node setup is just a proof of concept of a bigger architecture (with around 30 nodes). I personally would prefer use KVM, so we can use Kilo and Neutron, but for some political reasons, we are really pushed to use XenServer (no problem about XS itself, I think it is great), but we don't have enough time and "hands" to make it work.
Thinking about it,i would ask (maybe Bob will give me the best answer) what should be the best choise for use Openstack with XenServer regarding their versions?
Maybe an older XCP with Juno or Icehouse?
And what about VMWare as it is as XenServer in Group B?

Thank you again.

Hello Leandro,

From my experience OpenStack + XenServer is really difficult to build, but it work. Newest features like neutron, advanced cinder drivers, XenServer pool's, etc is not working well. At least with XenServer 6.2 and  Icehouse release. If you know both technologies and don't know which to choose then use KVM.
If you want to use XenServer then community member Bob Ball (bob.ball at citrix.com<mailto:bob.ball at citrix.com>) can help you more with this.

Best regards,
Martins

Hi Guys,
I'm trying to setup a 3 node (controller, neutron and compute) Openstack setup, but i'm having a lot of trouble regarding the XenServer(6.5) setup.
Looking around the internet for docs about XenServer as compute node, i've got the impression that the main effort of OpenStack is use KVM instead of XenServer, because the docs (and lots of another links outhere) are outdated.
May i consider it true? Should i forget about XenServer and move to KVM?
What do you guys think about that?
Thank you.
