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! |
SRU Justification:
[Impact]
* Nice to have feature requested by IBM - a systemd service monitoring
KVM guests.
* Adds a new systemd service, not enabled by default.
[Fix]
* Install the systemd .service file when installing linux-tools-host
[Test Plan]
* dpkg -c linux-tools-host_5.11.0-18.19_all.deb
./lib/systemd/system/kvm_stat.service
* Install the package and reboot
* Check if kvm_stat is present and not active after reboot:
ls -l /lib/systemd/system/kvm_stat.service
systemctl -a | grep kvm_stat
[Where problems could occur]
* Service can be enabled and started by mistake or by any further future
Makefile change (enabling all services installed by linux-tools-host).
* The service logs into /var/log/kvm_stat.csv (not journal!) and package does
not provide logrotate by default, thus the logging could eat entire
disk space.
