[Libvirt-cim] MigratevirtualSystemToHost reports "unsupported"

[Velayudham, Madan Ganesh (STSD / ESS SW)]

Hi Kaitlin,

Thanks for the troubleshooting tip.

We retried the invocation and the same result appeared. The following snippet related to migrateVirtualSystemToHost was found in the /tmp/libvirt-cim.log file.

Can you suggest us how to get around this?

Hi Sandeep,

I don't see anything obvious in the information you provided.  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).

Thanks!
