Edit the file: sudo vim /etc/libvirt/libvirt.conf.
Navigate to the desired text using your arrow keys.
Press i to go into insert mode, and edit the configuration.
When done editing, press ESC and save the file by entering :wq

After saving the file, make sure to either restart libvirtd, or reboot your system.

I believe what you're looking to change is the line #uri_default = "qemu:///system". Uncomment that line first, then replace "qemu" by "xen" so that the whole line should read uri_default = "xen:///system".

Note: It is always a good idea to take backups of configuration files before editing. In this case, sudo cp /etc/libvirt/libvirt.conf /etc/libvirt/libvirt.conf.bkp should do the trick, should you ever need to recover that file.

If you're new to Linux, here's a good tutorial on vim.

Can you please copy/paste the exact output? – baalali Mar 30 '19 at 16:44
output: sudo: vim: command not found – E Tab Mar 30 '19 at 16:58
Looks like vim is not installed. Try using vi instead of vim. – baalali Mar 30 '19 at 17:27
Or you could just install vim: sudo apt-get install vim. – baalali Mar 30 '19 at 17:37
