kvm创建磁盘挂载到虚拟机

[TOC]

方法1

1 ui节目添加一块500G磁盘名称叫做10.255.66.100-data.img

2 命令行缓存到添加到虚拟机 /data/kvm/disk是我创建磁盘路径 10.255.66.100是我虚拟机名称

virsh attach-disk 10.255.66.100 /data/kvm/disk/10.255.66.100-data.img vdb

3 临时生效磁盘命令写入xml文件防止重启后失效

virsh dumpxml 10.255.66.100 /etc/libvirt/qemu/10.255.66.100.xml

4 重新加载

virsh define /etc/libvirt/qemu/10.255.66.100.xml

方法2

1直接在yml文件修改存储-点击保存（需虚拟机关机）
