[root@room9pc01 ~]# lsmod | grep -i kvm
[root@room9pc01 nsd1902]# virsh list 查看正在运行虚拟机列表
[root@room9pc01 nsd1902]# virsh list --all 查看所有的

1.创建一台虚拟机

base-vm 虚拟机名称

2 启动虚拟机

virsh start 虚拟机名称 (启动虚拟机)

virsh console 虚拟机名称 (登录虚拟机)

virsh domblklist 虚拟机名称

qemu-img info 快设备

3 扩容磁盘

virsh blockresize --path 磁盘路径 --size 50G 虚拟机名称

[root@room9pc01 qemu]# virsh blockresize --path /var/lib/libvirt/images/b1.img --size 50G b1

4 分区扩容

进入虚拟机

]# LANG=C

]#growpart /dev/vda 1

6 扩容文件系统:

]# xfs_growfs /

原始盘 (后端盘) 918M 不能修改

前端盘

如果后端盘发生改变，则所有前端盘都需要重建。

vbr 虚拟交换机

cd /var/lib/libvirt/images/
[root@room9pc01 images]# cd /etc/libvirt/qemu/

虚拟机的创建 nsd 1902

拷贝配置文件:

[root@room9pc01 qemu]# cp /var/lib/libvirt/images/.node_base.xml /etc/libvirt/qemu/nsd1902.xml

创建磁盘文件:

cd /var/lib/libvirt/images

root@room9pc01 images]# qemu-img create -f qcow2 -b .node_base.qcow2 nsd1902.img 30G

修改配置名称 cpu 内存硬盘网卡

]#vim /etc/libvirt/qemu/nsd1902.xml

创建虚拟机

[root@room9pc01 images]# virsh define /etc/libvirt/qemu/nsd1902.xml

启动虚拟机

[root@room9pc01 images]# virsh start nsd1902
[root@room9pc01 images]# virsh console nsd1902
