I'm not sure exactly what you're trying to define a route for, so I'll answer the two possibilities that I can come up with:

If you want to define a route to the 192.168.193.0 subnet (with a BSD subnet mask of 255.255.255.0), the VM subnet mask you would use on the gateway statement would be 0 and you would omit the subnet value (since 192. is a class C address range)

If you want to define a route to the 192.168.192/22 supernet, your VM subnet mask would be 0.0.3.0 and your subnet value would be 0
