很久没有编译 libvirt了。
工作需要，重新编译。
[org_ref]: http://libvirt.org/compiling.html 很简单。 编译过程， 还是很多问题。
依赖包(给懒人参考）：
$ sudo apt-get install libtool libxml-xpath-perl libxml2 libxml2-utils python-dev automake autopoint xsltproc libxml++2.6-dev libdevmapper-dev libpciaccess-dev libnl-3-dev libnl-route-3-dev imagemagick libyajl-dev xmllint uniconvertor
勤快的家伙们，可以自己编译，自己查看，缺了每个包的功能。
libnl-route-3-200 - library for dealing with netlink sockets - route interface
libnl-3-200: library for dealing with netlink sockets
rpcgen: 这个包不需要安装，但是可以man一下。 之前在公司的wiki中，介绍过rpcgen。 可惜...
$ git grep RPCGEN
在libvirt中，src/remote/remote_protocol.x 产生：
$ tree -f |grep remote_protocol
$ git show eb826444f90c2563dadf148630b0cd6a9b41ba1e

编译完成，启动远程链接注意问题。

可以不启用用tls，config中修改一下，就可以了。
