XCP-ng local storage in XenServer

The XCP-ng virtualization platform is built on the XenServer. It is an open-source alternative to Citrix Hypervisor (previously XenServer), providing a comprehensive range of VM management functionalities.

In XCP-ng, local storage refers to the use of local disks or storage devices physically connected to the XCP-ng server to store virtual machine data, such as virtual hard disk files, ISO images, and snapshots. Local storage can give good virtual machine performance, but it lacks the flexibility and advanced features of shared storage systems such as iSCSI or NFS.

Steps to set up XCP-ng local storage in XenServer

We can run the following steps in order to set up local storage:

1. Firstly, confirm that the XCP-ng server has local disks available. Because using disks containing existing data can result in data loss, these disks should be allocated to VM storage.

2. Then create a new Storage Repository (SR) in the XCP-ng Center or via the command-line interface (CLI) for each local disk or partition we want to use; the SR will serve as the container for the VM data.

3. After creating the SR, we may need to format the local disks with the suitable file system. XCP-ng supports various file systems, including ext3, ext4, and XFS.

4. After configuring the SRs, we can connect them to VMs. When building or configuring a VM, we can specify which SR will house its virtual disks and other data.

5. If we have multiple XCP-ng servers and wish to activate HA, we’ll require shared storage (iSCSI, NFS, or external SAN) to ensure that VMs can be automatically transferred between hosts in the event of a server failure.

Conclusion

The configurations and particular processes may differ depending on the XCP-ng local storage version and management tool we’re using. Previously, XCP-ng was actively maintained and routinely updated, so new features and changes may have been implemented since then.
