I don't really know of other virtualization technology other than Xen, and I thank you for guiding me through this, but I have a few doubts related to the choice of a virtualization technology in a host with Asterisk:

- Isn't the fact that KVM is now included in the mainstream Linux kernel as of 2.6.20 a certain type of 'proof' that it could be stable enough compared to others (of course there could be licensing or other political/friendship issues)?

- Even if the virtual guests aren't totally stable and 100% reliable yet, wouldn't the use of KVM be better with Zaptel compatible cards than Xen, in architecture point of vue, as it is only a kernel module that -as far as I know- don't appear to be changing fundamental issues like IRQ handling or I/O scheduling in the kernel, and from the fact that virtual machines are treated like simple processes?

Thanks again for your help, and sorry if I was not 'that' convinced on
your first answer and sent a mail to Xen user mailing list to check if
they knew that issue (no answer yet). Now I almost believe you a lot. If
I understand well I have two options, recode Xen or abandon it. I'll
probably go for the 2nd choice and start looking at other solutions, KVM
seems to be a good choice and shouldn't interfere much with Asterisk
(again: as far as mailing lists say).

Let me try to understand this:

Xen is a (far) more mature virtualization technology than KVM, and it's been said that it's commercialization was rushed. So you're going to try KVM, which is still under heavy development, as a stable solution?
