Hi all,
I've got a weird issue, and I'm trying to confirm if it's a bug, and if so, if
there is a workaround until it is fixed.
The situation is this: If I virsh reboot <domain> --mode acpi, it will actually
reboot the domain cleanly (watching from the console allows me to see the full shutdown
messages, followed by a bootup). However, after this point, virsh domstate <domain>
provides the state "in shutdown". From what I read, this is only supposed to
persist for more than a tiny fraction of a second if there was a problem killing qemu or
cleaning up its resources which, to my knowledge, should not apply here since there is no
killing of qemu involved, just an acpi signal sent to the domain. Am I wrong? Either way,
the only way to run any start/stop type commands with virsh after running the reboot
command is to destroy the domain, obviously not very practical.
I've attached console output from my tests, and the log of the same time period
below.
System info: libvirt 4.8.0-2, qemu 3.0.0-3, linux 4.18.6.arch1-1, running on arch linux.
Thanks,
-Michael.
