Nova / Bexar is it really usable ?

Hello,

I installed Nova / Austin several months ago, but it was impossible to manage (create, stop, ...) virtual machines. Does version Nova / Bexar is more reliable and is it able to run multiple VMs on several different nodes (Xen or KVM, XenServer, Hyper-V)?

Thank you

Yes, but I think at Xen and not XenServer. It is possible to use Xen 3.4?

Nova currently only supports XenServer.

OK, thank you.

We want to create a Proof of Concept. We will install tall Nova services on a physical or virtual server, and Swift. We have two hypervisors; KVM on a first physical server and XenServer or Xen4.0 on a second physical server.

It Is a good context for evaluation?

I'm not sure Nova will work with Xen4.0 -- we have been testing it against 5.5 and 5.6fp1. Other than that, I think that would make a nice proof of concept.

Sorry, Just a last question: Is it possible to use Xen 3?

Doubtful. I wouldn't go any lower than 5.5.

Yep, it should in fact run all of those without issue. Let us know if you run into any problems and we'll be glad to help.

Actually, nova should support xen through libvirt. This code path is largely untested though.

XenServer uses Xen 3.4 underneath, so we know that the hypervisor works. You have three options:

XenServer, free to download, using OpenStack's XenAPI backend Xen Cloud Platform, open source equivalent of XenServer, using OpenStack's XenAPI backend Xen direct from http://Xen.org or from SLES or OEL or similar, using OpenStack's libvirt backend.

I'd recommend the first of these, but then I do work for Citrix ;-)
