Instead of trying to change connections after starting virsh, you can
use 'virsh -c qemu:///system' to force the correct connection to begin with.

This sounds like your version of virsh is self-built and installed into
/usr/local, but you don't have a self-built counterpart libvirtd also in
/usr/local running at the moment.
