1.虚拟机需要GNOME界面（如果是字符界面需要下载安装GNOME界面）
3.安装xshell（SecureCRT），xftp（WinSCP）或finalshell
进入/etc/sysconfig/network-scripts/ifcfg-ens33 ，配置如下：
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=417d6e6c-50f2-4e8f-8f11-a8ad9fd8dea3
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.100.130
NETMASK=255.255.255.0
GATEWAY=192.168.100.2
DNS1=192.168.100.2
DNS2=8.8.8.8
如下

清理yum源
安装
yum install -y qemu-kvm
设置软连接（相当于windows中的快捷方式）
ln -s /usr/libexec/qemu-kvm /usr/bin/qemu-kvm
测试环境
查看版本
yum install -y vnc-server tigervnc
[root@localhost ~]# cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:1.service
vim 打开/lib/systemd/system/vncserver@:1.service
systemctl daemon-reload
[root@localhost ~]# vncpasswd

[root@localhost ~]# systemctl restart vncserver@:1
[root@localhost ~]# systemctl enable vncserver@:1
Created symlink from /etc/systemd/system/multi-user.target.wants/vncserver@:1.service to /usr/lib/systemd/system/vncserver@:1.service.
root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.[root@localhost ~]# setenforce 0
临时关闭selinux防火墙 ：setenforce 0
查看selinux防火墙 状态：getenforce
永久关闭selinux防火墙需要到/etc/selinux/config 下更改配置文件
