Virtualbox More than 4 Serial ports?

Postby SkyQuake » 1. Dec 2017, 01:14

Hello,

I'm new to Virtualbox, and am trying it out. I have an old Fedora installation in a Clonezilla image that I am trying to virtualize on a Windows 10 system through Virtualbox. This old installation had an 8-port PCI serial card that I am going to transfer over to the new Windows 10 system. The extra serial ports are necessary to run old home automation equipment. Is there a way for Virtualbox to pass through 8 serial ports? I see that there is only an option for 4.

Thanks!

Not that I know of. 8 serial ports is not something a standard PC is capable of, and VirtualBox always emulates standard PC chipsets. You would need something like an 8 port USB serial adapter.

Would Virtualbox support passing through the serial ports of such a USB adapter from the host Windows 10 to the old guest Fedora that had a PCI 8-port card? I suppose it would bypass the 4 serial ports offered by Virtualbox natively.

Yes, a USB adapter would in principle be owned by the VM, so you could anything with it that any other PC could do with it. This would be separate from the 4 ports provided by the motherboard emulation.
