由於功能需要，體驗了手動編譯安裝Libvrt,還是碰到了不少問題，這里總結如下僅限於centos7：
1、configure: error: You must install the pciaccess module to build with udev
解決方案：yum install libpciaccess-devel.x86_64
2、configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt
解決方案：yum install device-mapper-devel
3、configure: error: libnl-devel >= 1.1 is required for macvtap support
解決方案：yum install libnl-devel.x86_64
4、configure: error: You must install the libyajl library & headers to compile libvirt
解決方案：yum install libxml2.x86_64 yum install libxml2-devel.x86_64
yum install yajl.x86_64 yajl-devel.x86_64
5、 error: Failed to connect socket to '/usr/local/var/run/libvirt/libvirt-sock': Connection refused
這個是virsh連接libvirtd守護進程的時候容易出現的問題，根本原因是libvirtd服務沒有啟動
解決方案：libvirtd -d
6、啟動Libvirt出現問題：libvirtd: error: Unable to obtain pidfile. Check /var/log/messages or run without --daemon for more
解決方案：
（1）查找到libvirtd.pid文件，根據libvirt的安裝不同，位置可能不同：
$ sudo find / -name libvirtd.pid
[sudo] password for cloud:
/usr/local/var/run/libvirtd.pid
（2）刪除：$sudo rm /usr/local/var/run/libvirtd.pid
（3）啟動：$sudo libvirtd -d
