A friend of mine is looking to build a virtual server, currently he is running 2008 with hyperv and 2vm's and then a few other machiens on other hardware.

I wasn't really able to find clear answer to my question or not.

He is looking to move his freepbx to a vm on hyperv ( yes it works already tried it ) HOWEVER his new one uses a pci fx card for the analogue lines. Can you dedicate a card such as one plugged into a pci slot on a server to a certain vm inside hyper V or esxi ?
 
You can pass it thru with esxi, but whether it will work well is another matter. Only really one way to find out. Can't speak to hyper-v. In general, nics and hbas tend to work well - other types of card, iffy.
 
will have to see if he can give it a shot, im sure he has a spare usb stick around and a spare drive to test it all on..
 
You can't pass through any add in cards to Hyper-V. Not even a raid card.

ESXi has the feature for 'supported' devices. Don't know if that means it will only work on that list of devices or that those are the only ones that they will officially support.

I'm going to have to just tell him to try it then, it would be nice to have all his servers virtualized even the phone pbx server..
 
Hyper-V right now won't do it (I think it might be in the next version? not sure). ESXi will.
 
This is interesting. Ze use a lot of dedicated dialin pc's at work and I'd like to consolidate it on 1 vmware server with a few modem cards. Looking forward to see the results of this.

Keep in mind that some phone/pbx/voicemail devices may have issues with running on VM's. You could get audio stuttering, etc.

it was running in a vm for a full year, perfectly, but now he added a pci phone card for anolog phone line that he has.. Right now it's running on a dedicated box, but he wants to cut power costs down and the amount of heat & units in this room.
 
Depending on the need, you can put an 8-port card in a low-power atom box running some flavor of asterisk and it works fine. I will note I am a big fan of VM, and my sole physical server now is a low-power atom for pbx in a flash due to concerns with audio quality.
 
For this sort of thing you should look in a dialogic media gateway. It's an appliance that your VM would connect to over IP. That'll let you even vmotion the VM.

Just get an ATA adapter for that analog line so the VM can connect to it via IP.

He doesn't want to do that, he bought the pci card witch works 100% so now we re going to put it on esxi and see if we can pass through the unit to the vm..
