Regarding ready installation images; I usually boot the rescue mode and ins= tall manually by creating partitions and untarring the base system, so perhaps Hetzner/Vultr provide installation media where virtio_random is already pre-blacklisted). Have a system available for any testing/debugging, or even just try to dete= ct if the issue would occur and not load the driver, if someone wants to point= me in the right direction. --=20 You are receiving this mail because: You are the assignee for the bug.
