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 the ldm 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:

primary# ldm create ldg1
primary# ldm ls -l ldg1
NAME             STATE      FLAGS   CONS    VCPU  MEMORY   UTIL  UPTIME
ldg1             inactive   ------

UUID
    6c908858-12ef-e520-9eb3-f1cd3dbc3a59

primary# ldm ls -l -p ldg1
VERSION 1.6
DOMAIN|name=ldg1|state=inactive|flags=|cons=|ncpu=|mem=|util=|uptime=
UUID|uuid=6c908858-12ef-e520-9eb3-f1cd3dbc3a59
