KVM Virtualization Directory-Based Storage Pool Configuration

External

• RHEL 7 Virtualization Administration - Directory-based Storage Pools

Internal

• Linux Virtualization Operations

Overview

This procedure declares a local directory as a storage pool.

One case when this is useful is when we want to share DVD ISO images with the guest for installation as -disk=.../some-image.iso,device=cdrom argument for virt-install. If the image is not declared as storage volume in a storage pool, libvirt will automatically build a storage pool for it, and sometimes build multiple storage pools for the same image, which is something we want to avoid.

Procedure

Create the new directory, or us an existing directory.

mkdir /iso-images

Set directory ownership:

chown root:root /iso-images

Set directory permissions:

chmod 700 /iso-images
