Qemu guest agent to install RPMs in guest VM from host machine
Hi, I want to be able to install RPM packages (available in host system at some path) to the guest VM and want this facility to be available as a tool. I am thinking of having a gemu guest agent (qemu-ga) running inside guest VM. I did not find any available command ("virsh qemu-agent-command <guest_vm> ...") which can do the same. I am planning to implement a command in qemu guest agent, which I can invoke from virsh like below. "virsh qemu-agent-command vm_01 \ '{"execute":"guest-rpm-install", \ "arguments":{"path":"/usr/local/bin/ABC.rpm"}} I am able to pass arguments from host to guest VM but how am I supposed to pass the whole RPM image from host to guest (which the guest agent can receive and install)? Regards, ~Puneet

why would you use a guest agent (which is primarily targeted for = virtualization-related tasks/coordination) rather than a generic remote = execution tools (like, well, plain ssh:) The only benefit/difference with the guest agent is that it doesn't = require a network connection. Do you have such a requirement?

exactly;-) So are you trying to come up with something isolated from = network completely? If not I'd go with a dedicated/different tool Thanks, michal
