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. <snip> device_parsing.c(257): Disk node: disk infostore.c(88): Path is /etc/libvirt/cim/Xen_Copy_Copy_RHEL52VM1 std_invokemethod.c(279): Method `MigrateVirtualSystemToHost' execution attempted std_invokemethod.c(230): Method parameter `ComputerSystem' validated type 0x1100 std_invokemethod.c(230): Method parameter `DestinationHost' validated type 0x1600 std_invokemethod.c(215): No optional parameter supplied for `MigrationSettingData' std_invokemethod.c(230): Method parameter `MigrationSettingData' validated type 0x1000 std_invokemethod.c(303): Executing handler for method `MigrateVirtualSystemToHost' misc_util.c(72): Connecting to libvirt with uri `xen' Virt_VSMigrationService.c(102): Using default values for MigrationSettingData param Virt_VSMigrationService.c(1351): Prepared migration job f64be851-e44a-4d3c-b4a8-bce814ceffe1 Virt_VSMigrationService.c(1283): Creating instance: root/virt:Virt_MigrationJob.InstanceID="f64be851-e44a-4d3c-b4a8-bce814ceffe1" Virt_VSMigrationService.c(1287): Failed to create job instance: 7 std_invokemethod.c(305): Method `MigrateVirtualSystemToHost' returned 7 misc_util.c(72): Connecting to libvirt with uri `xen' misc_util.c(199): URI of connection is: xen:/// misc_util.c(199): URI of connection is: xen:/// device_parsing.c(257): Disk node: disk infostore.c(88): Path is /etc/libvirt/cim/Xen_RHELVM-GUI-1 <snip> Can you suggest us how to get around this?

Hi,
I'm trying to perform a live move of a domU using libvirt-cim, but I'm receiving a CIM_ERR_NOT_SUPPORTED exception. I have attached the request and response xmls.
The same operation when tried through virsh command worked.
Please let me know if I'm missing something here.
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!
Thanks for the help.
Regards, Sandeep
