[Qemu-devel] [PATCH] Stop before shutdown

[Qemu-devel] [PATCH] Stop before shutdown

[Eduardo Felipe]

[-- Attachment #1: Type: text/plain, Size: 2130 bytes --]

Hi,

Attached patch adds a new option to stop the emulation just before shutdown.
This allows switching to monitor for selective committing of snapshoted
devices and such.

Regards,
Edu
