Since Ubuntu has KVM built-in (rather than being compiled as module) this should not be needed for Ubuntu.

However, once the kvm module is loaded, the service is _not_ started. Problem: Since the unit file does not specify a delay for the retries, Systemd restarts with a minimum delay a number of times before giving up and disabling the service. Which means a subsequent kvm module load will have kvm running without monitoring. Solution: Add an appropriate delay in the unit file. Reproduction: (1) Enable the kvm service via systemctl (2) Reboot (3) Verify that the kvm module is not loaded & kvm service not running (4) Load the kvm module via 'modprobe kvm' (5) Verify that the kvm service came up within the next minute. Preventive: yes Just use the attached patch and you're good!
