How to use Windows 10 OEM license in libvirt VM (<smbios mode='host' /> does not work as Windows seems to verify UUID; apparmor/security configuration changes may be needed)

domain.xml

<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
  <!-- ... -->
  <qemu:commandline>
    <qemu:arg value='-acpitable'/>
    <qemu:arg value='file=/some/path/slic.bin'/>
    <qemu:arg value='-acpitable'/>
    <qemu:arg value='file=/some/path/msdm.bin'/>
    <qemu:arg value='-smbios'/>
    <qemu:arg value='file=/some/path/smbios_type_0.bin'/>
    <qemu:arg value='-smbios'/>
    <qemu:arg value='file=/some/path/smbios_type_1.bin'/>
  </qemu:commandline>
</domain>

slic-dump

#!/bin/bash

set -e

cat /sys/firmware/acpi/tables/SLIC > slic.bin
cat /sys/firmware/acpi/tables/MSDM > msdm.bin
dmidecode -t 0 -u | grep $'^\t\t[^"]' | xargs -n1 | perl -lne 'printf "%c", hex($_)' > smbios_type_0.bin
dmidecode -t 1 -u | grep $'^\t\t[^"]' | xargs -n1 | perl -lne 'printf "%c", hex($_)' > smbios_type_1.bin

Thanks. I am wondering if it's possible to write a SLIC file manually based on the infos displayed in UEFI.

Why? If your licence is activated and the file does not exist then it is not used.

OK, I have understood now.

Note that this is a much better (and doesn't accidentally corrupt) way to generate the smbios extracts:

dmidecode -t 0 -u | awk '/^\t\t[0-9A-F][0-9A-F]( |$)/' | xxd -r -p > smbios_type_0.bin
dmidecode -t 1 -u | awk '/^\t\t[0-9A-F][0-9A-F]( |$)/' | xxd -r -p > smbios_type_1.bin

I expanded this to work with Proxmox - https://gist.github.com/xrobau/d98fe46c4677e46577ba2f20f35b783b

slic doesn't exist for me, do I just remove it or is there an alternative?

This is expected for newer windows versions. Just skip it and use what you have.
