Bug description:
Description: tools/kvm_stat: Add restart delay
Symptom: If the kvm service is enabled and the system rebooted,
Systemd's initial attempt to start the kvm unit file may
fail in case the kvm module is not loaded. 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!
