Hi, I have Ubuntu 14.04.1 (ubuntu-14.04.1-server-amd64.iso) guest running in a KVM host. The host is running Ubuntu 16.04. I'm trying to find out how Ubuntu 14.04.1 differentiates between virsh shutdown and virsh reboot commands issued in the host. I see that in both cases the ACPI event seen at the guest are exactly same. The guest however correctly shuts down on issuing "virsh shutdown" and correctly reboots on issuing "virsh reboot". syslog:Sep 25 12:33:51 ubuntu acpid: waiting for events: event logging is on syslog:Sep 25 12:34:46 ubuntu acpid: received input layer event "button/power PBTN 00000080 00000000" syslog:Sep 25 12:34:46 ubuntu acpid: rule from /etc/acpi/events/powerbtn matched syslog:Sep 25 12:34:46 ubuntu acpid: executing action "/etc/acpi/powerbtn.sh" syslog:Sep 25 12:34:46 ubuntu acpid: action exited with status 0 syslog:Sep 25 12:34:46 ubuntu acpid: 1 total rule matched syslog:Sep 25 12:34:46 ubuntu acpid: completed input layer event "button/power PBTN 00000080 00000000" syslog:Sep 25 12:34:46 ubuntu acpid: received netlink event "button/power LNXPWRBN:00 00000080 00000001" syslog:Sep 25 12:34:46 ubuntu acpid: rule from /etc/acpi/events/powerbtn matched syslog:Sep 25 12:34:46 ubuntu acpid: executing action "/etc/acpi/powerbtn.sh" syslog:Sep 25 12:34:46 ubuntu acpid: action exited with status 0 syslog:Sep 25 12:34:46 ubuntu acpid: 1 total rule matched syslog:Sep 25 12:34:46 ubuntu acpid: completed netlink event "button/power LNXPWRBN:00 00000080 00000001" syslog:Sep 25 12:35:02 ubuntu acpid: starting up with netlink and the input layer syslog:Sep 25 12:35:02 ubuntu acpid: 1 rule loaded syslog:Sep 25 12:35:02 ubuntu acpid: waiting for events: event logging is on syslog:Sep 25 12:36:13 ubuntu acpid: received input layer event "button/power PBTN 00000080 00000000" syslog:Sep 25 12:36:13 ubuntu acpid: rule from /etc/acpi/events/powerbtn matched syslog:Sep 25 12:36:13 ubuntu acpid: executing action "/etc/acpi/powerbtn.sh" syslog:Sep 25 12:36:13 ubuntu acpid: action exited with status 0 syslog:Sep 25 12:36:13 ubuntu acpid: 1 total rule matched syslog:Sep 25 12:36:13 ubuntu acpid: completed input layer event "button/power PBTN 00000080 00000000" syslog:Sep 25 12:36:13 ubuntu acpid: received netlink event "button/power LNXPWRBN:00 00000080 00000001" syslog:Sep 25 12:36:13 ubuntu acpid: rule from /etc/acpi/events/powerbtn matched syslog:Sep 25 12:36:13 ubuntu acpid: executing action "/etc/acpi/powerbtn.sh" syslog:Sep 25 12:36:13 ubuntu acpid: action exited with status 0 syslog:Sep 25 12:36:13 ubuntu acpid: 1 total rule matched syslog:Sep 25 12:36:13 ubuntu acpid: completed netlink event "button/power LNXPWRBN:00 00000080 00000001" syslog:Sep 25 12:36:27 ubuntu acpid: starting up with netlink and the input layer syslog:Sep 25 12:36:27 ubuntu acpid: 1 rule loaded syslog:Sep 25 12:36:27 ubuntu acpid: waiting for events: event logging is on Guest details: srinij@ubuntu:/$ lsb_release -a No LSB modules are available.
