kvm虚拟化学习笔记(十六)之kvm虚拟化存储池配置

1.创建基于文件夹的存储池（目录）

[root@node1 ~]# mkdir -p /data/vmfs
[root@node1 ~]#
[root@node1 ~]# ll /data/
total 12
drwxr-xr-x 2 root root 4096 Nov 22 09:59 iso
drwxr-xr-x 2 root root 4096 Nov 28 09:04 kvm
drwxr-xr-x 2 root root 4096 Nov 28 09:02 vmfs
[root@node1 ~]#
[root@node1 ~]# ll /data/kvm/
total 11436976
-rw-r--r-- 1 root root      393216 Nov 22 17:06 CentOS6.5-01_add.qcow2
-rwxr-xr-x 1 root root  7516192768 Nov 22 15:08 CentOS6.5-01.img
-rw-r--r-- 1 root root  2318139904 Nov 27 17:08 CentOS6.5-01.qcow2
-rwxr-xr-x 1 root root 10737418240 Nov 22 14:40 Ser08R2-01.img
[root@node1 ~]#

2.定义存储池与其目录

[root@node1 ~]# virsh pool-define-as vmdisk --type dir --target /data/vmfs
Pool vmdisk defined

[root@node1 ~]#

3.创建已定义的存储池

(1)创建已定义的存储池

[root@node1 ~]# virsh pool-build vmdisk
Pool vmdisk built

[root@node1 ~]#

(2)查看已定义的存储池，存储池不激活无法使用。

[root@node1 ~]# virsh pool-list --all
Name                 State      Autostart
-----------------------------------------
default              active     yes
vmdisk               inactive   no

[root@node1 ~]#

[root@node1 ~]# virsh pool-info vmdisk
Name:           vmdisk
UUID:           bbd57b00-ad6f-91a2-76a4-059042387903
State:          inactive
Persistent:     yes
Autostart:      no

[root@node1 ~]#

4.激活并自动启动已定义的存储池

[root@node1 ~]# virsh pool-autostart vmdisk
Pool vmdisk marked as autostarted

[root@node1 ~]# virsh pool-list --all
Name                 State      Autostart
-----------------------------------------
default              active     yes
vmdisk               inactive   yes

[root@node1 ~]#
[root@node1 ~]# virsh pool-start vmdisk
Pool vmdisk started

[root@node1 ~]# virsh pool-list --all
Name                 State      Autostart
-----------------------------------------
default              active     yes
vmdisk               active     yes

[root@node1 ~]#

5.在存储池中创建虚拟机存储卷

(1)在存储池中创建虚拟机存储卷

[root@node1 ~]# virsh vol-create-as vmdisk CentOS6.5-02.qcow2 20G --format qcow2
Vol CentOS6.5-02.qcow2 created

[root@node1 ~]# ll /data/vmfs/
total 196
-rw------- 1 root root 197120 Nov 28 09:10 CentOS6.5-02.qcow2
[root@node1 ~]#

(2)根据创建的虚拟机存储卷安装虚拟机

[root@node1 ~]# virt-install --name=CentOS6.5-02 --os-variant=RHEL6 --ram 1024 --vcpus=1 --disk path=/data/vmfs/CentOS6.5-02.qcow2,format=qcow2,size=20,bus=virtio --accelerate --cdrom /data/iso/CentOS-6.5-x86_64-bin-DVD1.iso --vnc --vn
cport=5910 --vnclisten=0.0.0.0 --network bridge=br0,model=virtio --noautoconsole

6.存储池相关管理命令

(1)在存储池中删除虚拟机存储卷

[root@node1 ~]# virsh vol-delete --pool vmdisk CentOS6.5-02.qcow2
Vol CentOS6.5-02.qcow2 deleted

[root@node1 ~]# ll /data/vmfs/
total 0
[root@node1 ~]#

(2)取消激活存储池

[root@node1 ~]# virsh pool-list --all
Name                 State      Autostart
-----------------------------------------
default              active     yes
vmdisk               active     yes

[root@node1 ~]# virsh pool-destroy vmdisk
Pool vmdisk destroyed

[root@node1 ~]# virsh pool-list --all
Name                 State      Autostart
-----------------------------------------
default              active     yes
vmdisk               inactive   yes

[root@node1 ~]#

(3)删除存储池定义的目录/data/vmfs

[root@node1 ~]# virsh pool-delete vmdisk
Pool vmdisk deleted

[root@node1 ~]# virsh pool-list --all
Name                 State      Autostart
-----------------------------------------
default              active     yes
vmdisk               inactive   yes

[root@node1 ~]# ll /data/
total 8
drwxr-xr-x 2 root root 4096 Nov 22 09:59 iso
drwxr-xr-x 2 root root 4096 Nov 28 09:04 kvm
[root@node1 ~]#

(4)取消定义存储池

[root@node1 ~]# virsh pool-list --all
Name                 State      Autostart
-----------------------------------------
default              active     yes
vmdisk               inactive   yes

[root@node1 ~]# virsh pool-undefine vmdisk
Pool vmdisk has been undefined

[root@node1 ~]# virsh pool-list --all
Name                 State      Autostart
-----------------------------------------
default              active     yes

[root@node1 ~]#
