Looking at virt-manager 0.8.6 on a RHEL test system here - it looks like I can modify a guest VM with virt-manager. Select the VM I want, go to the Information button, Add Hardware...PCI Host Device, and then select the device I want to associate with that VM. Looks straightforward enough - I wonder if the interface really means PCI or if it also works with PCI-e?
Has anyone done this with a Brooktrout faxmodem and Windows VM? And again - if I do this, it will be on brand new hardware and everything today has the virtualization stuff these days.

Ideally, I'd like to do this one with virt-manager on RHEL. Or Fedora. Maybe eventually on RHEV. If I do this, it would be new hardware - not sure if those Brooktrout modems are PCI-e or just PCI. - Greg -----Original Message----- From: Alex Williamson [mailto:[email protected]] Sent: Friday, June 15, 2012 11:56 AM To: Eric Blake Cc: Greg Scott; [email protected] Subject: Re: [fedora-virt] Support for modems and other such physical hardware?

Google guesses this is a PCI device, so you'll need a system with VT-d or AMD-Vi (if it's indeed a legacy PCI device vs a PCI-e device, it's often easier to make those work on VT-d).
