Has anyone gotten KVM to pass a BIOS serial to the guest OS?  I realize that there's nothing specific to unraid's implementation of KVM, but I've followed the documentation pertaining to passing sysinfo to the guest here: https://libvirt.org/formatdomain.html#elementsSysinfo

 

It never yields a serial number in the OS.  I'm testing with Windows 10 as I have an application that requires the BIOS number to run.

 

I saw this post about adding a serial #, but it seems like treading into Unraid OS modification which I'd like to stay away from if possible.

You are the bomb.  That worked!  Thank you.

It barked on my entry name 'release' number so I just removed it, but after that it worked.
