ubuntu14.04 manually installing QEMU and Libvirt

Install the QEMU and libvirt environments in a new ubuntu14.04 with source code compilation. You need to be aware of an installation order issue. It is recommended that you install QEMU before installing Libvirt. Because, when libvirt up, it detects the hypervisor it needs to use. In addition, their installation is best to specify the installation path to the/usr directory so that the Libvirt and QEMU commands can be used globally directly after installation. and Libvirt by default is by calling the QEMU command under/usr/bin to get the QEMU version and commands used. Therefore, to ensure that the libvirt can be easily called to the QEMU command, the installation of two components will need to be specified in the/usr directory.
