Using Universally Unique Identifiers
Each domain is assigned a universally unique identifier (UUID). The UUID is assigned when a domain is created. For legacy domains, the UUID is assigned when the ldmd
daemon initializes.
Note:
The UUID is lost if you use theldm migrate-domain -f
command to migrate a domain to a target machine that runs an older version of the Logical Domains Manager. When you migrate a domain from a source machine that runs an older version of the Logical Domains Manager, the domain is assigned a new UUID as part of the migration. Otherwise, the UUID is migrated.
You can obtain the UUID for a domain by running the ldm list -l
, ldm list-bindings
, or ldm list -o domain
command. The following examples show the UUID for the ldg1
domain:
