Re: [Xen-devel] Windows HVM no longer boots with AMD Ryzen 3700X

["Joost Heijne" <joost.heijne@xxxxxxxxxxxxxxx>]

Hi,

I ran into this list looking for a solution for the exact same problem
as described here. I'm trying to migrate an existing Windows
Server 2016 image to a Ryzen 3900x and encountered the same
difficulties. I disabled the processor's SMT feature in the BIOS and
now it works perfectly.

Regards,

Joost Heijne

Any update on the topic?
