Hyper-V vs ESXi sharing of serial ports

Hello,
Can anyone with experience in Hyper-V/ESXi recommend the best solution to support 4-8 VM's per host in Windows and Linux to share serial ports. I have a need in a hospitality setting to install an add-in card and devote one serial port per VM in the most reliable way possible. I am not interested in serial to IP technology as that has licensing implications outside the scope of this discussion.

Thanks.

I would recommend the use of VMware vSphere and USB to Serial Devices, and then allocate the USB Device to the VM.

This works for us, and we've been doing this for 11+ years with VMware vSphere.

USB devices to Serial work much better than serial ports, because of issues with server interrupts.

HOW TO: Add and Connect a USB Device to a Virtual Machine, hosted on VMware vSphere Hypervisor ESX 4.1 ESXi 4.1, ESXi 5.0

I do not have any usb devices. Only serial. So if I have a single HOST running EXSi and 8 VM's running Windows Server 2012R2 I can assign one physical serial port from the multi-port hardware card installed on the host to the VM's individually?

Thanks.

Yes you can but I'm recommending a solution that works without issue!

Let's say I want to run Hyper V vs. ESXi... do you know if I can run multiple usb to serial devices and handle it this way as it would be less expensive probably?

Hyper-V does not support USB!
