I need to attach a fax modem to a VM running on my VMware host. My host is a Dell R510 and I have a PCI-e fax modem already installed. When I tried searching for answers I saw where PCI had some issues and recommended using USB. So I have both USB & PCI-e, Brand, USR fax modems.
When I go to, Edit Virtual Machine, and add hardware, when I select PCI device, it says Unavailable and say: There are no devices reserved for PCI passthrough on the host.
Can someone please explain how to attach a fax modem to a VM?
