Make sure your username is part of the libvirt group.
Try running sudo adduser <username> libvirt. This fixed the problem for me.
1) Verify you have all packages you need
$ sudo apt install -y qemu-kvm libvirt0 libvirt-bin virt-manager bridge-utils
$ sudo systemctl enable libvirt-bin2) Verify that libvirtd and libvirt-bin are up and running.
$ sudo service libvirtd status
$ sudo service libvirt-bin statusYou are likely going to need to make sure your user owns the libvirt socket, change out the username:username with your actual username
sudo chown username:username /var/run/libvirt/libvirt-sockMore in general
