I suspect you would be better off with some virtualization platform more like OpenVZ ('containers' rather than VM's) - and probably without any hardware<div>installed (ie SIP to SIP - leave the gateways to a different part of the network).</div>

</div>I tried tdm400+xen DOM0+asterisk years ago, on a single processor<br>
machine but gave up. zttest returned good results, but analogue<br>
quality has intermittently very poor quality and it made telephone<br>
conversations difficult to understand. Especially a problem when<br>
hourly cron jobs would start on all VMs at exactly the same time, but<br>
was a problem at other times too. Plus the fact people who used the<br>
phone more often then me didn't report the problem, so I thought it<br>
was fine.<br>
<br>
Plus the general fact I didn't really like the idea of running<br>
Asterisk on DOM0, and running it on DOMU seemed to imply even more<br>
overheard, as DOM0 would have to process the interrupts and pass them<br>
to the DOMU.<br>
<br>
Unfortunately I don't remember what scheduler I used, maybe sedf?<br>
<br>
I suspect a multi-processor system would be a lot better suited for<br>
the task. Also might be OK if you don't use zaptel hardware... I seem<br>
to remember these cards generate a huge number of interrupts.<br>
<br>
While this was with Asterisk, I suspect my results were not specific<br>
to Asterisk in anyway.<br>
