Everything's working great so far with a few exceptions I can live with. I have 5 VM's running, mostly lightweight stuff, including my security camera system. For that I'm using Win XP and feeding the PV-149 CCTV capture card through via VT-d. Video streaming from BlueIris is working just fine and I also have PIAF running all of the phones, PFSense as a server on a stick running DHCP and DNS forwarding and the VMWare mobile appliance so I can watch it on my iPad.
I've started to install SageTV but it's not done yet. So far everything's got plenty of pep. No quality problems with PIAF so far either.
Speaking of PIAF, the years old post about SIP trunking between Asterisk and a Cisco 1760 that has gotten so much attention, yeah, that's old school now! I just converted to a Linksys SPA3102 for my PSTN connectivity and it's working perfectly. I think it might forward calls through a little more quickly too. The 1760 developed a bad fan and I couldn't see spending money on it. I'll probably try to ebay it.
Finally, I'm thinking about passing through the USB bus for SageTV to take advantage of the improved throughput but I believe I'll need to be careful not to allocate the same bus that has the keyboard (KVM) on it. More later...
