Machines through libvirt and clearly doesn't need sudo to run. But you know what bothers me Virt-manager is mature and feature-complete, and RedHat has discontinued it in favour of cockpit. I say in this video that AMD invented virtualization support in. Virt-manager is a desktop user interface for managing virtual Gnome Boxes is a quick fast way to create VM, but lacks the options I think I will need going down the road to replace VirtualBox. When I run $ sudo virt-manager KVM connects. Virt-manager by clicking the icon it is not connecting to kvm. I just installed qemu-kvm and virt-manager. make sure your application needs sudo to function or otherwise you should refrain from using sudo. However, running applications (GUI or otherwise) with sudo gives them root's privileges and this might pose major security, stability and integrity problems and this one was and still the same so use precaution and common sense with it. Once we are connected to the VPN we are good to go for accessing VMs with their.
Starting from Ubuntu 19.10, using sudo with GUI applications will assume root's home directory and not the current user's home directory. In the previous article (Part -1) we setup KVM Virtualization and used. The old issue was that sudo used to write and modify the applications configuration files in the current user's home directory changing their permissions and ownership from the current user to root which will render them inaccessible to the current user and thus mess up the current user's home directory's contents to the point that GUI applications might not run anymore or run with errors.
Starting from Ubuntu 19.10 and later, you can run GUI applications with sudo. Some people will still warn you not to do so on Ubuntu without even knowing why! What you've been told is a remnant of an old issue (tale) that is not an issue anymore. To put this in other words, Virt-manager is a graphical front-end for libvirt. I've been told that running GUI application with sudo is not a good Virt-manager, short for Virtual Machine Manager, is a graphical user interface application used for managing virtual machines through libvirt.
