libvirt编译安装错误提示及解决方法

centos7手动编译安装Libvirt常见问题

由于功能需要，体验了手动编译安装Libvrt,还是碰到了不少问题，这里总结如下仅限于centos7：

1、configure: error: You must install the pciaccess module to build with udev

解决方案：yum install libpciaccess-devel.x86_64

 

 

2、configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt

解决方案：yum install device-mapper-devel

 

3、configure: error: libnl-devel >= 1.1 is required for macvtap support

解决方案：yum install libnl-devel.x86_64

 

 

4、configure: error: You must install the libyajl library & headers to compile libvirt

解决方案：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

 

这个是virsh连接libvirtd守护进程的时候容易出现的问题，根本原因是libvirtd服务没有启动

解决方案：libvirtd -d

 

6、启动Libvirt出现问题：libvirtd: error: Unable to obtain pidfile. Check /var/log/messages or run without --daemon for more

解决方案：

（1）查找到libvirtd.pid文件，根据libvirt的安装不同，位置可能不同：

$ sudo find / -name libvirtd.pid
[sudo] password for cloud: 
/usr/local/var/run/libvirtd.pid

（2）删除：$sudo rm /usr/local/var/run/libvirtd.pid

（3）启动：$sudo libvirtd -d

（1）

checking libxml2 xml2-config >= 2.6.0 ... configure: error: Could not find libxml2 anywhere (see config.log for details).

#apt-cache search libxml2

# apt-get install libxml++2.6-2

# apt-get install libxml++2.6-dev

（2） 

configure: error: You must install the GnuTLS library in order to compile and run libvirt

 

# apt-get install gnutls-bin(可省)

#  apt-get install libgnutls-dev

 （3）

configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt

# apt-get install libdevmapper-dev libdevmapper

 （4）

configure: error: libnl-devel >= 1.1 is required for macvtap support

# apt-get install libnl-dev

 （5）

# ./configure --prefix=/usr --libdir=/usr/lib64 --localstatedir=/var --sysconfdir=/etc --with-hal=yes --with-udev=yes

checking for UDEV... no

configure: error: You must install libudev-devel >= 145 to compile libvirt

# apt-cache search libudev-dev

libudev-dev - libudev development files

# apt-get install libudev-dev

 （6）

configure: error: You must install libpciaccess-devel >= 0.10.0 to compile libvirt

# apt-cache search libpciaccess-dev

libpciaccess-dev - Generic PCI access library for X - development files

# apt-get install libpciaccess-dev

  （7）

 configure: error: You must install python-devel to build Python bindings

sudo apt-get install python-dev

注：有时依然不能用virsh nodedev-dumpxml pci_0000_00_19_0

#./configure --prefix=/usr --libdir=/usr/lib64 --localstatedir=/var --sysconfdir=/etc --with-hal=yes --with-udev=yes --with-polkit=yes

....

checking for POLKIT... no

configure: error: You must install PolicyKit >= 0.6 to compile libvirt

# apt-get install libpolkit-agent-1-0 libpolkit-backend-1-0 libpolkit-gobject-1-0 libpolkit-gtk-1-0
