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

Virtualization Host Network Operations

• Bridged Networking Configuration
• Attaching a Guest Directly to a Virtualization Host Network Interface

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

Connect to the Guest VM

   virsh console

Adding Storage to Guests

Adding Storage to Guests

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.
