[SIZE=2][SIZE=2]Unable to connect to libvirt.
Not 100% sure about this, but I specifically choose to use a Xen connection when remote connecting virt-manager to a Xen host (using SSH RSA keys) and when the host is running as KVM host, then select the default QEMU/libvirt.

So I'd suspect you are choosing the wrong option to connect with.
