Connecting USB, serial & X25 modems to a VM

I have a physical management server that has a 3 modems connections:

1) a USB 3G modem which has a SIM card in it to send SMS

2) a dialup serial modem that connects to an external USR
    Robotics 56kbps modem (sort of 13-15 years old dialup
    modem) that connects to a physical phone line

3) an X25 PSI interface


Questions:
If we were to virtualize this management server, how are
these 3 modems going to connect to the VM?

Where can I hunt for these drivers or can I port the drivers
over from the current physical management server when
doing P2V?

USB is the answer and USB pass through

With serial modems we use serial to USB devices and my EE article

Also use VM Direct Path IO for PCIe devices.

See an example of VM Direct Path I/O here

I'm on IBM HX5 blades (IBM Bladecenter H) : not sure if those
2 USB ports on the blades allow me to connect the USB to
DB9 serial converter & still enable the modem to send SMS
out?  Anyone tried this before?

I'll attach a photo of the SMS modem (which has one DB9 serial
cable connected to it to connect to the current x3650 DB9 serial
port & another RJ11 phone line connected to it).

Or shall I still connect this dialup SMS modem to another physical
x3650 server & the virtualized management server had to send
messages via LAN to the physical server to be sent out?  Just exploring

We have successfully connected USB to serial adaptors to blades, and added them to VMs, for use with Serial Modems.
