一、部署环境和软件包准备
- 1.1 环要求
龙芯3A4000
- 1.2 软件包清单
qemu-kvm-ev-2.12.0-33.1.lns7.3.loongnix.mips64el
libvirt-4.5.0-23.lns7.3.loongnix.mips64el
virt-install-1.5.0-7.lns7.3.loongnix.noarch
tigervnc-1.3.1-11.fc21.loongson.1.mips64el
二、环境搭建–服务器
- 2.1 软件包安装
因为loongnix的yum源中已经包上述软件，因此直接通过yum安装即可
yum install -y qemu-kvm-ev libvirt virt-install
- 2.2 服务启动
systemctl start libvirtd && systemctl enable libvirtd
- 2.3 本地镜像准备
wget http://ftp.loongnix.org/os/loongnix-server/1.7/isos/mips64el/loongnix-server-1.7.2003.iso
- 2.4 虚拟机配置xml文件准备
[root@node001 zwl]# cat /loongnix_test.xml

三、环境搭建–具有图形界面的客户机
yum install -y tigervnc
四、在服务器中创建虚拟机
- 3.1 生成硬盘镜像文件
[root@node001 zwl]# qemu-img create -f qcow2 loongnix_test.qcow2 30G
Formatting 'loongnix_test.qcow2', fmt=qcow2 size=32212254720 cluster_size=65536 lazy_refcounts=off refcount_bits=16
- 3.2 导入虚拟机配置
[root@node001 zwl]# virsh define loongnix_test.xml
定义域 loongnix_test（从 loongnix_test.xml）
- 3.3 启动虚拟机
[root@node001 zwl]# virsh start loongnix_test
域 loongnix_test 已开始
- 3.4 查看当前虚拟机状态
[root@node001 zwl]# virsh list
Id 名称 状态
----------------------------------------------------
16 loongnix_test running
- 3.5 显虚拟机端口信息
[root@node001 zwl]# virsh vncdisplay loongnix_test
:1
五、通过客户机vnc链接已经启动虚拟
在客户机执行vncviewer，调出vnc客户端
输入服务器ip及虚拟机对应的端口，点击connect即连接,如下
10.130.56.127:1
六、虚拟机安装
连接后虚拟机安装步与正常物理机安装步骤一致，不再单独介绍
