Hi, So to make clarify some things for you, creating QEMU command line is not simple. Virt-manager is GUI application written in python that communicates with libvirt (virtualization library) using libvirt-python APIs. Virsh is a CLI that is written in C and communicates with libvirt using directly C API. Libvirt itself is a virtualization library that offers APIs to manage and run virtual machines and libvirt is the one that creates the command line and starts the QEMU process. Virt-viewer is yet another project that is using again libvirt API in order to open console for your virtual machines. Now to answer your question, there is no other simple way how to create and start the QEMU process unless you want to do it manually which I would not recommend, the best for you is to stick with libvirt. To automate it you can create a script looking like this: virsh --connect qemu:///system start UbuntuMATE1804 virt-manager --connect qemu:///system --show-domain-console UbuntuMATE1804 If you notice, in order to directly open the console you need to specify connection as well because virt-manager can be configured to use multiple connections and there is no thing as default connection. Virsh also has the same parameter but it has some default connection which is most likely the same but since it will be one script you can configure the same connection for virsh as well. Pavel
