@olivierlambert You and the rest of the Vates team are already my Xen heros! I've been running XCP-ng 8.3 Beta on my home lab since August. I was impressed to see the new virtual TPM option in XO this weekend after pulling and compiling the latest source code. (BTW: Windows 11-23H2 BitLocker works flawlessly with the new vTPM support.) XCP-ng and XO truly just keep getting better and better! Hopefully, nested-virtualization of Windows Hyper-V on Xen will get solved before too long since a good variety of capable hypervisor options is important for a healthy and competitive virtualization ecosystem. This is especially true now as we all look to see what Broadcom will do as the new owner of VMware.
