Re: [Xen-users] AsteriskNOW on Xen Choppiness

[francisco javier funes nieto <esencia@xxxxxxxxx>]

Hi,

I've a 'very stable' domU (PV) working with Asterisk + FreePBX + 2BRI
Digium Clone Card (PCi-E)  in a Xen 3.4.2 from sources with Debian
Lenny 2.6.26 for dom0/domU and pci-passthrough (uf!)

The system works well for two months and seems very stable with
medium-full load. It's based in a very cheap motherboard from ASUS and
an AMD x2 processor.
