Hi Kaitlin, Thanks for the troubleshooting tip. We retried the invocation and the same result appeared.

The return error of CIM_ERR_NOT_SUPPORTED is interesting, as both versions of libvirt support the MigrateVirtualSystemToHost() method. I'm wondering if something is happening in the CIMOM before our method even gets called. Can you enable debugging in the libvirt-cim providers and then provide the log output you get? You can enable debugging using the following: export CU_DEBUG="/tmp/libvirt-cim.log" Then restart the CIMOM in the same terminal (to make sure it picks up the environment settings).

Hi Kaitlin, Thanks for your suggestion. Our RHEL 5.3 did not have either cimserver_[planned|current].conf file. Hence we enabled the flag repositoryIsDefaultInstanceProvider, now the migrateVirtualSystem call succeeds.

However, it's possible for another provider set (or some other package) to overwrite the change me make. So it's difficult to ensure that this option is set properly. We should at least add a note to our README that indicates this should be set. -- Kaitlin Rupert IBM Linux Technology Center kaitlin(a)linux.vnet.ibm.com
