ubuntu15.04下编译 libvirt

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。
