创建基于文件夹的存储池
基于文件夹的存储池：
[root@ubuntu01 ~]# mkdir /data/vm_pool
[root@ubuntu01 ~]# virsh pool-create-as --name vmdir_pool --type dir --target /data/vm_pool
Pool vmdir_pool created
基于文件夹的存储池：
[root@ubuntu01 ~]# mkdir /data/vmfs_pool
[root@ubuntu01 ~]# virsh pool-create-as --name vmfs_pool --type fs --source-dev /dev/sdb1 --source-format ext4 --target /data/vmfs_pool
Pool vmfs_pool created
查看存储池状态
[root@ubuntu01 ~]# virsh pool-list --all

[root@ubuntu01 ~]# virsh pool-info vmdir_pool

在存储池中创建卷
[root@ubuntu01 ~]# virsh vol-create-as --pool vmdir_pool --name vm_disk01.raw --capacity 10G --allocation 1G --format raw
Vol vm_disk01.raw created
- --capacity 10G #总容量
- --allocation 1G #初始大小
查看存储池的卷信息
[root@ubuntu01 ~]# virsh vol-list [--pool] vmdir_pool
