Re: [libvirt] [PATCHv2] network: fix network driver startup for qemu:///session

This should resolve https://bugzilla.redhat.com/show_bug.cgi?id=958907 Recent new addition of code to read/write active network state to the NETWORK_STATE_DIR in the network driver broke startup for qemu:///session. The network driver had several state file paths hardcoded to /var, which could never possibly work in session mode.
