[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v2] event: Add source information to SHUTDOWN
Libvirt would like to be able to distinguish between a SHUTDOWN
event triggered solely by guest request and one triggered by a
SIGTERM or other action on the host. qemu_kill_report() is
already able to tell whether a shutdown was triggered by a host
signal (but NOT by a host UI event, such as clicking the X on
the window), but that information was then lost after being
printed to stderr.
Enhance the shutdown request path to take a parameter of which
way it is being triggered, and update ALL callers. It would have
been less churn to keep the common case with no arguments as
meaning guest-triggered, and only modified the host-triggered
code paths, via a wrapper function, but then we'd still have to
audit that I didn't miss any host-triggered spots; changing the
signature forces us to double-check that I correctly categorized
all callers.
Here is output from 'virsh qemu-monitor-event --loop' with the
patch installed:
event SHUTDOWN at 1492639680.731251 for domain fedora_13: {"guest":true}
event STOP at 1492639680.732116 for domain fedora_13: <null>
event SHUTDOWN at 1492639680.732830 for domain fedora_13: {"guest":false}
Note that libvirt runs qemu with -no-quit: the first SHUTDOWN event
was triggered by an action I took directly in the guest (shutdown -h),
at which point qemu stops the vcpus and waits for libvirt to do any
final cleanups; the second SHUTDOWN event is the result of libvirt
sending SIGTERM now that it has completed cleanup.

I did not wire up the RESET event to report guest-triggered, although
I had to plumb that through all the guests since qemu has options that
allow remapping reset to shutdown. It's easy to add that if we want
it in v3.
The replay driver needs a followup patch if we want to be able to
faithfully replay the difference between a host- and guest-initiated
shutdown (for now, the replayed event is always attributed to host).
v2: retitle (was "event: Add signal information to SHUTDOWN"),
completely rework to post bool based on whether it is guest-initiated
v1: initial submission, exposing just Unix signals from host
