For example the system UUID as reported when booted on bare metal (also matches dmidecode -s system-uuid in Ubuntu) isĤC 4C 45 44- 00 48- 44 10-8044-XXXXXXXXXXXXīut the system UUID that is reported in Windows when booted in Virtualbox isĤ4 45 4C 4C- 48 00- 10 44-8044-XXXXXXXXXXXX However, it is not a completely different UUID, but the same one with the first 3 groups somewhat reversed. I troubleshot a bit with the setup and discovered that Windows 10 reports a different system UUID if booted in VirtualBox than on bare metal. Is there something that I am missing here? Does an EFI config require a different way to pass ACPI tables to the Windows guest? If I boot into Windows 10 natively, Windows activation shows that it is activated. I have also tested passing the MSDM table along with the SLIC table, but this does not seem to resolve the issue. To be clear, I am sure to change theĬommands to reflect efi instead of pcbios. This works fine and well for MBR/BIOS booting, however when we attempt a similar setup with EFI booting, the Windows 10 guest does not keep its activation status. We add a series of extra data withĬode: Select all Expand view Collapse view VBoxManage setextradataĬode: Select all Expand view Collapse view VBoxManage setextradata "VBoxInternal/Devices/acpi/0/Config/CustomTable" "/path/to/SLIC.bin"Ĭode: Select all Expand view Collapse view VBoxManage modifyvm -hardwareuuid Ubuntu is used as the default OS, and VirtualBox is configured to use the Windows partition via raw VMDK disk access. In our environment, we have dual-boot MBR/BIOS setups with Ubuntu 18.04LTS and Windows 10 Pro. I am having an issue with a Windows 10 guest keeping its activation status when booted in VirtualBox in EFI mode.
