Virtualization Host Storage Operations

Storage Pool Configuration

• Disk-Based Storage Pool Configuration
• Partition-Based Storage Pool Configuration
• Directory-Based Storage Pool Configuration
• LVM-Based Storage Pool Configuration
• Storage Pool Deletion

Storage Volume Configuration

• Storage Volume Creation
• Storage Volume Cloning
• Storage Volume Deletion

Create a Guest Virtual Machine

Virtualization host storage and networking must be configured as a prerequisite to creating guest virtual machines. Once storage pools and storage volumes are made available, and the networking is configured, guest virtual machines can be created with:

virt-install

virsh define

Start/Stop Guest VMs

virsh start

virsh shutdown

Cloning a Guest VM

TO replicate and verify:

• Shut down the guest with virsh shutdown.
• Export the XML configuration with virsh dumpxml.
• Copy the XML definition and the disk image to the target node.
• Edit the XML as needed.
• Define the guest with virsh define.
