1、安装及编译步骤
感谢提供步骤和错误解决参考： https://www.codeleading.com/article/1288836853/
- tar -xvf libvirt-4.5.0.tar.xz 【安装包：https://download.libvirt.org/】
- cd libvirt-4.5.0
- ./autogen.sh
- make
- make install
- 完成后检查：
-- 查看：virsh list --all
-- 开启libvirt：libvirtd -d
-- 查看是否启动：ps -le | grep libvirtd
2、make过程中的错误
错误1：error: 'xdr_u_int64_t' undeclared (first use in this function)

解决来源：https://listman.redhat.com/archives/libvir-list/2013-May/077764.html
但是这个作者好像不是这一个原因
- 在"./autogen.sh"后进行操作
- grep -rn "XDR_CFLAGS =" * 为了查看包含
XDR_CFLAGS定义的文件- 分别打开
Makefile和src/Makefile文件，找到其中的XDR_CFLAGS =定义行，添加上-I/usr/include/tirpc
即：XDR_CFLAGS = -I/usr/include/tirpc- 再进行make即可
注：因为我是一起加的，所以不确定是不是只用添加Makefile和src/Makefile这两个文件其中之一即可，可自行尝试。
3、make install的错误
错误1：/usr/bin/mkdir -p ""/usr/local/etc/libvirt/nwfilter""
解决：
- **grep -rn "NWFILTER_DIR" *** 【找到nwfilter文件的生成路径】
- 删除2149、2722行多出来的引号
4、检查过程中的错误

非常感谢分享！
5、手动创建virbr0（若未自动创建情况下）
ifconfig或ip a后未看到有virbr0网卡
参考操作：
（1）创建新的虚拟网络
- 用一个xml文件定义default网络
virsh net-define /etc/libvirt/qemu/networks/default.xml
注：这两个参考步骤中default文件所处文件夹不同，我用的是1的路径。
若default.xml文件不存在，则先创建：
<network>
<name>default</name>
<bridge name="virbr0"/>
<forward/>
<ip address="192.168.122.1" netmask="255.255.255.0">
<dhcp>
<range start="192.168.122.2" end="192.168.122.254"/>
</dhcp>
</ip>
</network>
（2）设置virbr0自启
virsh net-start default
virsh net-autostart default
（3）检查配置
ip a
查看是否有virbr0了
（4）关于创建桥接网络接口virbr0-nic
使用 ip 命令验证桥是否存在：
- ip link show type virbr0 （完成上述步骤，输入这步可得到下述内容）
java5: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000 link/ether 52:54:00:9a:8c:49 brd ff:ff:ff:ff:ff:ff
使用 ip 命令，查询以 virbr0 网桥为主的接口：
- ip link show master virbr0 （若无输出，则手动添加）
java6: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel master virbr0 state DOWN mode DEFAULT group default qlen 1000 link/ether 52:54:00:48:3f:0c brd ff:ff:ff:ff:ff:ff
- 生成virbr0-nic，并将此接口添加到网桥virbr0
sudo ip tuntap add dev virbr0-nic mode tap % 创建一个 TAP 接口
sudo ip link set dev virbr0-nic down % 设置接口状态为 DOWN
sudo ip link set dev virbr0-nic address 52:54:00:9a:8c:49 % virbr0-nic 的 MAC 地址设置为与 virbr0 相同
sudo ip link set dev virbr0-nic master virbr0 % 将 virbr0-nic 接口添加到 virbr0 网桥
检查：
- ip link show virbr0-nic
- ip link show master virbr0
