1.創建一臺虛擬機

base-vm 虛擬機名稱

2 啓動虛擬機

virsh start 虛擬機名稱 (啓動虛擬機)

virsh console 虛擬機名稱 (登錄虛擬機)

virsh domblklist 虛擬機名稱

qemu-img info 快設備

3 擴容磁盤

virsh blockresize --path 磁盤路徑 --size 50G 虛擬機名稱

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

4 分區擴容

原始盤 (後端盤) 918M 不能修改

前端盤

如果後端盤發生改變，則所有前端盤都需要重建。
