Can't create new virtual machine with Virt-manager

After going through the whole setup, I would get this error through backtrace:

File "/usr/share/virt-manager/virtManager/netlist.py", line 346, in validate_network
    netobj.start()
	  File "/usr/share/virt-manager/virtManager/network.py", line 104, in start
	      self._backend.create()
	  File "/usr/lib/python2.7/site-packages/libvirt.py", line 2755, in create
	      if ret == -1: raise libvirtError ('virNetworkCreate() failed', net=self)
	      libvirtError: Unable to create bridge virbr0: File exists

Hence, I attempted to follow https://wiki.archlinux.org/index.php/Bridge_with_netctl to set up my network bridge and try again, and I'd still get the same error.

I also tried to do sudo virt-manager but I'd get:

** (virt-manager:16835): WARNING **: Could not open X display
No protocol specified

(virt-manager:16835): Gdk-ERROR **: error: XDG_RUNTIME_DIR not set in the environment.

I want to get KVM working using a gui and so I choice virt-manager, but now I'm stuck and don't know where to go from here.
