Hi Daniel, here's from my personal experience: Our setup at ng-voice is a little weird sometimes: We've rented some virtual servers at a german provider (who uses Xen). On these virtual servers we've installed OpenVz, which for us is absolutely great, if you are just working with Linux-Servers. While Xen is a rather complete virtualization, OpenVz is lightweight and comes in handy, if you just want to logically separate servers. We've got each IMS component (P-/I-/S-CSCF, HSS, Application-Servers, Databases) running on a dedicated OpenVz Container, which is really great. We've even got a CentOs-Container running on a Debian OpenVz, which is started "on-demand" in order to build RPM-Packages. With OpenVz you can even move Containers from one host to another, theoretically with zero downtime (doesn't work with SEMS, don't know about other software). For our IMS-setup, we work with RTP-Relaying, which works great within virtualization, i cannot complain. At another customer (a fibre provider in Germany), we're running all the infrastructure on Xen-only. An infrastructure provider takes care of the administration, but those servers run poorly (RTP-Relaying is okay but everything else is really slow). Conclusion for me: VoIP on virtual servers can work great, but the virtualization infrastructure needs to be administered properly which may not be an easy task, if you are new in this subject.

I haven't heard anyone using Asterisk in large production systems in other virtualization than OpenVZ. Asterisk depends a lot on timers and these aren't reliable enough in Vmware and Xen when putting load on the media server. I would love to hear about a successful implementation :-) on other platforms but so far I haven't. While waiting, OpenVZ works great. /O

Same preference-- especially when call load gets high or there is conferencing / call recording. ---Fred On Aug 28, 2012, at 2:19 AM, Daniel-Constantin Mierla <miconda(a)gmail.com> wrote:

Hey Klaus, We use solaris as host AND guest ;) solaris is slightly different to normal VM systems in that you can't really load up "any OS" into the guest. There are branded zones that support a few flavours of linux (ala redhat, etc). However, in our experience the Solaris OS is really solid for all we need. you can read up alot here - http://www.oracle.com/us/products/servers-storage/solaris/solaris11/overvie… Also there is some really nice network virtualisation you can do too.

Hi Daniel, not evaluation, but if you use it in production then you are required to buy a OS support contract. We however have standardised on Sun hardware which includes support for Solaris 11 in our production environment. So, yes a good point you make if you are going to be using in production on non-sun hardware you will need to pay Oracle ;( cheers Jason On Wed, Aug 29, 2012 at 7:46 AM, Daniel-Constantin Mierla &lt;miconda(a)gmail.com > > On 8/28/12 6:09 PM, Jason Penton wrote: > > No. We use solaris11. > > > IIRC, solaris 11 was free for evaluation purposes, has that changed? > > BTW, since mainstream opensolaris was discontinued, anyone knows what is > the best derivative (if that is at all)? > > Cheers, > Daniel > > > But yes on any hardware > On Aug 28, 2012 5:56 PM, "Daniel-Constantin Mierla" &lt;miconda(a)gmail.com&gt; > >> Hello, >> >> On 8/28/12 10:33 AM, Jason Penton wrote: >> >> Hey Daniel, >> >> We use Solaris virtualisation and it works great.
