Subject: [Qemu-devel] Unix signal to send ACPI-shutdown to Guest
Date: Sat, 28 Apr 2018 23:59:41 +0100 [thread overview]
Message-ID: <ba020090-1877-6b9a-891d-dbfbabf25c71@ymail.com> (raw)
Ive been looking into the possibility of using a unix signal to send an
acpi shutdown request to a VM, and came across a posting on this l in
March 1. See
https://lists.nongnu.org/archive/html/qemu-devel/2017-03/msg04169.html
To summarise to refresh memories there was a patch proposed using
SIGINT followed by discussion as to why SIGINT wasnt ideal because it
would cause regressions for anyone relying on the existing handling of
SIGINT, and various other signals were considered including HUP & USR1 &
USR2 all of which are already used for something else.
Is SIGPWR a suitable candidate, I have made a patch to use SIGPWR but as
Im new to QEMUs internals Im not sure if there are any circumstances in
which an alternative handler is registered for SIGPWR which might conflict?
Regards
Andrew
