An upstream user was also reporting that he updated his host and his engine
VM to Centos 7.4 and it failed to reboot the engine VM with 7.4 kernel
hanging at
"Probing EDD (edd=off to disable)...ok". He manually forced the old 7.3
kernel via grub menu and his engine VM correctly booted.
I wasn't able to reproduce it here.
