On-board serial port compatibility?
-
Hi,
Can you tell more precisely what do you want to achieve functionally speaking?
-
@uisRiveraSig What chipset is used for the serial ports? My guess is that it's a special MOXA serial chipset (non-16550) and requires a special driver that XCP/Xen does not natively support.
-
@livierlambert We are trying to migrate from VMWare to XCP so we want to enable those two on-board serial ports, the goal here is to be
able to communicate with them. -
@ndrew It uses ITE8786E. Where could we find drivers for this?
-
@uisRiveraSig What are you trying to use the serial ports for?
- XCP console?
- Dom0 Serial port (ie. UPS monitor)?
- DomU/VM?
-
@ndrew Its going to be used for digital I/O
-
@uisRiveraSig Since the device is not need for Xen Console or Dom0 then you can try a PCI pass-thru to the VM or use a USB device and pass it to the VM and just use the needed driver in the VM directly.

@ndrew
I too would like to pass thru a serial port on Dell R460 server host to a vm running linux. I would like to use this to talk to a lighting system with this VM rather than using a stand alone desktop. -
@ouble-e If you serial ports show up as a PCI or USB device then you can pass it to a VM. Most normal on-board serial ports can not be directly used in a VM.
Use
lspciandlsusbto check your devices. -
@ndrew I did not see a serial port listed. I'll just get a USB version and plug in to server and see if I can pass thru it. If it works, I can get rid of another Destop server and be fully virtual.
Thanks for your hellp.
