安装最新版本（v3.2.0）
Debian GNU/Linux 10 (buster)
# 安装依赖 # gettext >= 0.19.6 # python >= 3.4 # gtk3 >= 3.22 # libvirt-python >= 0.6.0 # pygobject3 >= 3.22 # libosinfo >= 0.2.10 # gtksourceview >= 3 # 安装 Virt Manager 工具 git clone https://github.com/virt-manager/virt-manager.git cd virt-manager git checkout v3.2.0 -b v3.2.0 virtinst/build.cfg # prefix = /usr/local ./setup.py install --reocrd install.logs # virtinst/build.cfg：默认会安装到 /usr 目录下，但它会安装某些模块（这会修改系统的原有模块），所以我们修改安装目录 # --reocrd install.logs：记录安装文件，将来在卸载时使用；
on macOS Big Sur 11.2.3（失败）
参考 GitHub – jeffreywildman/homebrew-virt-manager 仓库
我们遇到 Given no hashes to check 131 links for project ‘pip’: discarding no candidates 问题，简单折腾之后并未解决，所以我们不弄了（毕竟想安装试试，不行就算了）；
安装的可执行程序
Manage virtual machines with virt-manager
virt-install，安装新的虚拟机，a command line tool which provides an easy way to provision operating systems into virtual machines.
virt-viewer，a lightweight UI interface for interacting with the graphical display of virtualized guest OS. It can display VNC or SPICE, and uses libvirt to lookup the graphical connection details.
virt-clone，a command line tool for cloning existing inactive guests. It copies the disk images, and defines a config with new name, UUID and MAC address pointing to the copied disks.
virt-xml，a command line tool for easily editing libvirt domain XML using virt-install’s command line options.
virt-convert，a command line tool for converting OVF and VMX VM configurations to run with libvirt.
virt-bootstrap，a command tool providing an easy way to setup the root file system for libvirt-based containers.

常见问题汇总
客户端不断地提示输入 SSH 密码
Virt-Manager to Remote host – continuous password prompt over ssh
ubuntu – (KVM) virt-manager stuck in password prompt after open VM – Server Fault
问题描述：
打开远程连接中的虚拟机时，**不断的**提示输入 SSH 密码
原因分析：
虚拟机的 Display 使用 Spice server，而其近支持本地连接
解决方案：
1）方法一：Menubar => View => Details => Display Spice/Display VNC => Address: All interfaces
2）方法二：将 SSH 公钥复制到主机，即实现免密登录；
Unable to complete install: xxx Could not open ‘/path/to/iso’: Permission denied
问题描述：
在创建虚拟机后，当启动时产生如下错误：

原因分析：
镜像文件名 Microsoft Windows 2000 [Professional + Server + Advanced Server + Datacenter Server] SP4.iso 包含特殊字符；
解决方案：
重命名文件，去掉在文件名中的特殊字符；
