Hello,
On behalf of the QEMU Team, I'd like to announce the availability of the
fourth release candidate for the QEMU 10.0 release. This release is meant
for testing purposes and should not be used in a production environment.

Followng hmp/qmp commands are implemented for pressing virtual
sleep button,
hmp: system_sleep

These commands put the guest into suspend or other power states
depending on the power settings inside the guest.
These hmp/qmp command are in '*_*' format, it is int
The function qemu_wakeup_suspend_enabled combines the suspend
and wakeup together. However, the microvm doesn't support
wakeup yet. Suspend is enabled here, but wakeup doesn't
actually work for microvm now.
