Kvm virtualization learning notes (16)-kvm virtualization storage pool Configuration

Http://koumm.blog.51cto.com/703525/1304196

1. Create a folder-based storage pool directory)

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://img1.51cto.com/attachment/201310/2/703525_1380741331bOuI.png "height =" 203 "/>

2. Define the storage pool and Its Directory

# virsh pool-define-as vmdisk --type dir --target /data/vmfs

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://img1.51cto.com/attachment/201310/2/703525_1380741331OTeb.png "height =" 89 "/>

3. Create a defined storage pool (1) create a defined storage pool

# virsh pool-build vmdisk

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://img1.51cto.com/attachment/201310/2/703525_1380741332kHx8.png "height =" 96 "/>

(2) view the defined storage pool. The storage pool cannot be used if it is not activated.

#virsh pool-list --all

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://www.bkjia.com/uploads/allimg/131227/203214CM-3.png "height =" 148 "/>

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://www.bkjia.com/uploads/allimg/131227/2032143H1-4.png "height =" 167 "/>

4. Activate and automatically start the defined storage pool

# virsh pool-autostart vmdisk# virsh pool-start vmdisk

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://www.bkjia.com/uploads/allimg/131227/2032142K4-5.png "height =" 326 "/>

Here, the vmdisk storage pool has been created. You can create a virtual disk file directly in this storage pool.

5. Create a virtual machine storage volume in the storage pool (1) create a virtual machine storage volume in the storage pool

# virsh vol-create-as vmdisk oeltest03.qcow2 20G --format qcow2

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://img1.51cto.com/attachment/201310/2/703525_1380741338bfOS.png "height =" 139 "/>

(2) install the VM Based on the created VM storage volume

virt-install --name=oeltest03 --os-variant=RHEL6 --ram 1024 --vcpus=1 --disk path=/data/oeltest03.qcow2,format=qcow2,size=20,bus=virtio --accelerate --cdrom /data/iso/oel63x64.iso --vnc --vncport=5910 --vnclisten=0.0.0.0 --network bridge=br0,model=virtio –noautoconsole

The installation process is omitted. For more information about how to install linux on kvm, see http://koumm.blog.51cto.com/703525/1289627.

NOTE 1: The KVM storage pool is mainly a management method. You can create a storage pool by attaching the storage directory and lvm logical volume. After the VM storage volume is created, the remaining operations are no different from those without storage volumes.
Note 2: The KVM storage pool should also be used for VM migration tasks.

6. storage pool related management commands (1) create virtual machine storage volumes in the storage pool

# virsh vol-delete --pool vmdisk oeltest03.qcow2

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://www.bkjia.com/uploads/allimg/131227/20321452N-7.png "height =" 144 "/>

(2) Cancel activating the storage pool

# virsh pool-destroy vmdisk

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://www.bkjia.com/uploads/allimg/131227/203214CC-8.png "height =" 293 "/>

(3) Delete the storage pool definition directory/data/vmfs

# virsh pool-delete vmdisk

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://www.bkjia.com/uploads/allimg/131227/2032144340-9.png "height =" 303 "/>

(4) Cancel defining a storage pool

# virsh pool-undefine vmdisk

650) this. width = 650; "style =" border-bottom: 0px; border-left: 0px; border-top: 0px; border-right: 0px; "title =" image "border =" 0 "alt =" image "src =" http://www.bkjia.com/uploads/allimg/131227/203214F59-10.png "height =" 281 "/>

Configuration and management of the kvm storage pool have been completed.
