Dear All,
I looking for a method to send a message from my guest machine to the
host side when my program on guest machine is finished.
I have a monitor on the QEMU QMP side, it is possible to send a
message by using QMP on the guest machine?
Or there is a better way?
Thanks
Jimmy
The common methods from easiest to most complicated:
1. If you want to shut down the virtual machine at that
point anyway, just do so, when the shutdown tells the
VM to power off, qemu will exit and/or signal QMP.
2. Have your program create a file on a shared file
location, then your code on the guest (or another host)
can detect its appearance and proceed.
3. Have your program send a "network" message (such as
sending a packet to a port on the host) which will
signal your code on the host (or another guest).
Enjoy
