Not sure about that issue since I don’t use Windows 11 (I stayed on 10) but I did do some experiments a few months ago and documented how to bypass all of those requirements (including TPM) when installing 11 on bhyve. Maybe skipping it altogether can help get your setup running. You can take a look at my post here: https://xyinn.org/blog/freebsd/install_windows_11_bhyve Jonathan Vasquez PGP: 34DA 858C 1447 509E C77A D49F FB85 90B7 C4CA 5279 Sent with ProtonMail Secure Email Sent from Proton Mail for iOS. -------- Original Message -------- On Thursday, 11/27/25 at 09:31 Andrea Venturoli <ml@netfence.it> wrote: Hello.

I have no previous experiences with swtpm (and I find it hard to get a good howto/tutorial); TPM passthrough works for me (but obviously not on machines without TPM).
