i use one of these.

The device gets an ip addres in a dedicated lan for serial port servers.
an tcp/ip port is mapped to a serial port.

so you can have many vm's with 1 serial each, or multiple serial ports 
on some vm's

there is downloadable software for linux and windows. or you can use a 
opensource standardized tool on linux called socat.

you can get them in various sizes depending on need.

optinally you can make your own using a software called ser2net if you 
have a raspberrypi or similar micro machine.

kind regards
