Won't comment on VMware and * except that [EMAIL PROTECTED] seems to work fine :) We are starting to use Xen a lot more here - it's "paravirtualization" makes stuff run *a lot* faster - stopping, pausing, restoring a machine is very fast compared to VMWare plus you can migrate a vm machine from one Xen platform to another over the Internet *live* ... With respect to hardware, Xen2 did allow the "hypervisor" to control access to selected PCI devices on a per "domain" (virtual machine) basis. But this has changed recently (there are differences between Xen3 and Xen2 handling of hardware access). It used to be you could hide the PCI device from the domain0 kernel and then build a guest domain kernel that could "see" the hardware. I was hoping that testing would find it "just works" out of the box with digium and related hardware but such is not the case :) I think to get asterisk to work "pure" IP fashion (with no fxo/fxs cards etc) should be easier but you may have to configure the "stock" asterisk server a bit differently. So it looks like it will take a bit more investigation to figure out how to get asterisk working fully with Xen3. If I get anything going I will post to the list - hopefully an asterisk guru on the list has already figured it out :) Cheers, -- Graham Todd Bellanet.org tel/tél 613-236-6163 x2443
