From: Wenchao Xia <xiaw...@linux.vnet.ibm.com> Qemu system emulator reports only fails that make people confused about why, when it is invoked with nbd block device tring to connect qemu-nbd server. In fact qemu will try connect server for several times but server only accept one connect by default. I paid some times to find out why it fails. This patch add special text to explain how to use it in such case.
