安装Hypervisor软件
openEuler 22.03 LTS/openEuler 20.03 LTS/Kylin V10 SP2/Kylin V10/BC Linux 21.10/UOS V20（1050e）/CULinux 3.0/CentOS 7.5（5.10.0）/Tlinux3.1/UOS V20（1050u2e）/Kylin V10 SP3/BC Linux 8.2
- 执行如下命令，安装必要的工具软件和库文件。
- 对于Tlinux3.1：请执行yum install -y libvirt* virt-install virt-viewer edk2*
- 对于BC Linux 8.2：
- 其他OS：请执行yum install -y libvirt* virt-install virt-viewer edk2* edk2-devel edk2-help
- openEuler 20.03 LTS/BC Linux 21.10在安装库文件时，若提示“Unable to find a match: virt-install”，请参见openEuler 20.03 LTS/BC Linux 21.10安装virt-install时出错，提示“Unable to find a match: virt-install”处理。
- CULinux 3.0在安装库文件时，若出现源代理过期或不可用，请替换成openEuler 22.03的源后执行yum install -y --nogpgcheck libvirt* virt-install virt-viewer edk2* edk2-devel edk2-help解决。
显示如下，表示安装成功。
