Using already running qemu about avatar2 HOT 3 CLOSED

Hi there!
For now, QemuTarget would be responsible for spawning the QemuInstance.

If you want to attach to another Qemu instance, you could advice Qemu to spawn a GDBServer as well, and attach to it using the GDBTarget! Just add:
-gdb tcp::127.0.0.1:[PORT] to your command line arguments for Qemu. Additionally, if you want to halt the CPU on startup, add also the -S flag. Note that this way, you won't be able to access features of avatar-qemu like remote memory.

If you need access to Qemus QMP, you could set the Monitor protocol of your GDBTarget to qmp.

This may work like this (assuming the port for qmp is 9999):

qmp = QMPProtocol(9999, origin=self) 
gdbtargetInstance.protocols.monitor= qmp
qmp.connect()

This would require your Qemu instance started with the qmp server:
-qmp tcp:127.0.0.1:9999,server,nowait

Note that this is not tested and just written from my memory - normally we use the QemuTarget to drive QEMU, and we haven't implemented a RemoteQemuTarget yet - but this could be totally done the way described above. :)

Thanks for the feedback, I will give it a try!

As there where no further comments, I'm closing the issue for now.
