[ovirt-users] Re: Issues deploying 4.4 with HE on new EPYC hosts

Oof, I butchered his last name, but the quote I found was this: "Details: Tom Lendacky from AMD writes[4] -- "The idea behind 'virt-ssbd' was to provide an architectural method for a guest to do SSBD when 'amd-ssbd' isn't present. The 'amd-ssbd' feature will use SPEC_CTRL which is intended to not be intercepted and will be fast. The use of 'virt-ssbd' will always be intercepted and therefore will not be as fast. So a guest should be presented with 'amd-ssbd', if available, in preference to 'virt-ssbd'. It seems for these EPYC CPUs with qemu on 8.1, virt-ssbd isn't an option anymore and it has to be amd-ssbd for the VM to work?
