Debian Cloud kernel images


Debian has a cloud kernel initiative where they now have linux images optimized for performance on hypervisors and also contain the bare minimum modules needed to boot on major hypervisor platforms which is good for security. Though with the upcoming lockdown feature the extra modules can still be made off limits for attackers if not used.

This kernel version is available in buster and stretch backports which means we probably can’t use it for our purposes but good to consider for later.



We could use testers here.

    since it is as far as I know not much used in the cloud.
  • VirtualBox guest utilities might break or some other breakage.


  • This is unrelated to Qubes-Whonix since in Qubes-Whonix the kernel
    selection is not up to Whonix, but up to Qubes. (Same as Qubes Debian
