virConnectOpen chooses qemu:///session before qemu:///system

[Neil Wilson]

If you call virConnectOpen using a NULL parameter then the hypervisor search sequence will find and connect to the unprivileged 'qemu:///session' uri ahead of 'qemu:///system' for a non-root user - even if the user in question is a member of the libvirtd group.

Due to the somewhat unsophisticated selection criteria in 'qemu_driver.c"

        conn->uri = xmlParseURI(qemu_driver->privileged ?
                                "qemu:///system" :
                                "qemu:///session");

where 'privileged' is '1' if the process is running as root.
