KVM Virtual machine-Storage pool configuration grooming (RPM)

1. Create a folder-based storage pool (directory)

2. Define the storage pool and its directory

1

# virsh pool-define-asvmdisk --type dir --target /data/vmfs

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

1

# virsh pool-build vmdisk

(2) To view the defined storage pool, the storage pool is not activated and cannot be used.

1

#virsh pool-list --all

4. Activating and automatically starting a defined storage pool

1

2

# virsh pool-autostart vmdisk

# virsh pool-start vmdisk

Here the Vmdisk storage pool has been created and you can create virtual disk files directly in this storage pool.

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

1

# virsh vol-create-asvmdisk oeltest03.qcow2 20G --format qcow2

(2) Install the virtual machine based on the virtual machine storage volume created

1

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 slightly

Note 1:KVM Storage pool is mainly a management mode, you can mount the storage directory, LVM logical volume to create a storage pool, virtual machine storage volume after the creation of the complete, the remaining operations and no storage volume of the way no difference.
Note 2:KVM storage pools are also used for virtual machine migration tasks.

6. Storage pool-related management commands (1) Create a virtual machine storage volume in a storage pool

1

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

(2) Deactivate storage pool

1

# virsh pool-destroy vmdisk

(3) Delete the directory defined by the storage pool/data/vmfs

1

# virsh pool-deletevmdisk

(4) To cancel the definition of a storage pool

1

# virsh pool-undefine vmdisk

To this KVM storage pool configuration and management operation is complete.

[Email protected] kvmimg]# virsh pool-define-as vmdisk--type dir--target/data/kvmimg/
Pool Vmdisk defined
2. Create a defined storage pool
[Email protected] kvmimg]# Virsh pool-build vmdisk
Pool Vmdisk built

3. View the defined storage pool, the storage pool is not activated and cannot be used

5. Create the Qcow2 virtual machine storage volume in the storage pool, and then you can install the system directly using the Qcow2 disk file.
[Email protected] kvmimg]# Virsh vol-create-as vmdisk test06.qcow2 20G--format qcow2
Vol Test06.qcow2 Created
6. Delete Storage Pool command grooming
[Email protected] kvmimg]# Virsh vol-delete--pool vmdisk test06.qcow2 #删除刚刚创建的
