Online of LDom resource may fail due to incompatibility of LDom configuration file with host OVM version (2814991)

Last published : Sep 23, 2026
If you have a cluster running LDom with different OVM versions on the hosts, then the LDom configuration file generated on one host may display error messages when it is imported on the other host with a different OVM version. Thus, the online of LDom resource may also fail.
For example, if you have a cluster running LDom with OVM versions 2.2 on one and OVM 2.1 on the other node, the using XML configuration generated on the host with OVM 2.2 may display errors when the configuration is imported on the host with OVM 2.1. Thus, the online of LDom resource fails.
The following error message is displayed:
ldm add-domain failed with error Failed to add device
/ldom1/ldom1 as ld1_disk1@primary-vds0 because this device
is already  exported on LDom primary. Volume ld1_disk1
already exists in vds primary-vds0.
Workaround: If the CfgFile attribute is specified, ensure that the XML configuration generated is compatible with the OVM version installed on the nodes.
