Thanks Dale for responding.
Actually, these guest VMs may or may not have scp, ftp, etc. What is assured is that they have the QEMU guest agent running and there is a possibility of having additional commands if required.
Let me put up my problem.
have a project environment where guest VMs are getting created and
destroyed based on some (irrelevant) parameters (these guest VMs are
instantiated with QEMU guest agent running and with any possible changes
in that). There is a module in host which is controlling all this. I
need to do following things from within that module.
1. Whenever a new guest VM is created, take (predefined) RPM packages from host to guest VM and install them.
2. Start a script in guest VM (at certain events).
3. Start a process in guest VM (at certain events).
I thought to address above issues by having a QEMU guest agent
running inside guest VM which has one new command, to which I somehow
pass RPMs using "virsh qemu-guest-agent ..." command.
existing qemu-ga code, I saw some examples where they fork() and
execle() some stuff. I though I can achieve  and  using the same
But, I was getting stuck at  in how to transfer files from host
to guest and do something with them. I thought I should be able to
transfer files using channel like socket/virtio, but was not getting the
clue on how to use them.
