Managing Oracle VM Server Repositories

This Chapter contains information on managing Oracle VM Server repositories. It contains:

■Oracle VM Server Repositories

7.1Oracle VM Server Repositories

A repository is used for live migration of guests and for local storage.

A list of the Oracle VM Server repositories is in:

/etc/ovs/repositories

A configuration file for mounting repositories is in:

/etc/ovs/repositories.options

You can add a repository using the ovs-makereposcript, and remove them using the ovs-offlinerepo-dscript.

Repositories are managed by Oracle VM Agent. If you need to manually manage the repository daemon, you can use following commands:

/etc/init.d/ovsrepositories [startstopstatusrestartreload]

7.1.1 Repository Configuration File

A list of the Oracle VM Server repositories is in:

/etc/ovs/repositories

The format used in the repository file is:

uuid source

The uuid parameter is the UUID (Universally Unique Identifier) of the repository. The source parameter is the block device or NFS path to the file system used as a repository.

7.1.2 Repository Mount Options

You can create an optional repository option file which contains mount options for storage repositories. The repository option file must be named:

/etc/ovs/repositories.options
