[PATCH 0/4] Add a new -action parameter |
Date: |
Tue, 8 Dec 2020 14:14:46 -0500 |
This is a follow up to the proposal to add a "-no-panicstop" option to QEMU
that would allow us to
control whether the VM is paused or allowed to continue running without
intervention from a management layer
when a guest panic occurs. See the inital thread and replies for details:
https://lore.kernel.org/qemu-devel/1601606494-1154-1-git-send-email-alejandro.j.jimenez@oracle.com/
>From that discussion came a request for a generic mechanism to group options
>like -no-shutdown, -no-reboot, etc,
that specify an action taken by QEMU in response to a guest event (reboot,
shutdown, panic, and watchdog
expiration are the current options). The existing options would translate to
the new option, like:
* -no-reboot --> "-action reboot=shutdown"
* -no-shutdown --> "-action shutdown=pause"
Please share any questions or comments.
Regards,
Alejandro
