1) make xenconsoled exit gracefully if xcs dies 2) daemonize xenstored before binding to xenstored socket 3) wait to close stdio in xenstored until we're ready to accept connections (so that PID=`xenstored --output-pid` doesn't return until it's ready to accept connections) 4) updates tools/misc/xend for these changes Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Rusty Russell <rusty@rustycorp.com.au> Signed-off-by: Christian Limpach <Christian.Limpach@cl.cam.ac.uk>
