HI!
Microsoft certificates for Secure Boot expire in June 2026

Will AHV, CVM, and VM legacy boot continue to function properly after the certificate expires?
Secure Boot expiration will only affect guest VMs using UEFI?

      There is no answer to my question in the KB. It only specifies what needs to be done for VMs with Uefi deployed on AHV.


      The question is how this will affect AHV and CVM? Do they need to be updated separately?
      If I remember correctly, AHV and CVM don't use UEFI. Therefore, there's no need to do anything with them or the host.
