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-bin

2) Verify that libvirtd and libvirt-bin are up and running.

$ sudo service libvirtd status
$ sudo service libvirt-bin status
