You can update your version of JunOS from the CLI with the following command:
request system software add [jinstall_package]
Running your router(s)
Now you have a base olive image. Qemu allows you to use this as a base for other images and only writing the changes to your “slave” images saving on disk space! You can also use less memory for each Qemu instance.
Create a new image off of your base image. Repeat for all your routers you want to emulate:
qemu-img create -b olive-base.img -f qcow2 R1.img
Start your router and then telnet to it:
