Well, the background is that the instance provider for Virt_MigrationJob
is none of our providers. I found no implementation nor a registration
of one provider for Virt_MigrationJob (as Jay already mentioned). But
within the code you can find calls back to the CIMOM, that do
createInstance(), modifyInstance() and deleteInstance() on the
Virt_MigrationJob instances. This can only mean, that the instance(s) of
Virt_MigrationJob are stored in the CIMOM's repository (where also the
schema is located) and are handled by Pegasus' internal provider. And
this internal provider is responsible for setting the "instanceid". So
now I can only suppose ... the provider is setting "instanceid" instead
of "InstanceID" for ein calls. One interesting test case would be doing
the gi with the uppercase notation. Please can you provide me this
result ? Thanks.
wbemcli gi
http://root:password@localhost/root/virt:Virt_MigrationJob.InstanceID=
<http://root:password@localhost/root/virt:Virt_MigrationJob.instanceid=
>"2eb7e2ca-6197-4e50-9590-7cd05064d242"
Below are the outputs of ein and gi with the uppercase notation.
wbemcli ein http://root:password@localhost/root/virt:Virt_MigrationJob
localhost:5988/root/virt:Virt_MigrationJob.instanceid
="066259d5-4c5a-4b1f-991f-0d839f105a68"
wbemcli gi http://root:password@localhost/root/virt:Virt_MigrationJob.
InstanceID="066259d5-4c5a-4b1f-991f-0d839f105a68"
localhost:5988/root/virt:Virt_MigrationJob.InstanceID
="066259d5-4c5a-4b1f-991f-0d839f105a68"
OtherRecoveryAction,RecoveryAction,ErrorDescription,ErrorCode,DeleteOnCompletion=TRUE,PercentComplete,Priority,Owner,Notify,UntilTime,LocalOrUtcTime,RunStartInterval,RunDayOfWeek,RunDay,RunMonth,JobRunTimes=1,ElapsedTime,StartTime=20080201081420.535009+480,ScheduledStartTime,TimeSubmitted,JobStatus,CommunicationStatus,OperatingStatus,DetailedStatus,PrimaryStatus,HealthState,Status="Running",StatusDescriptions,OperationalStatus,InstallDate,Caption,Description,ElementName,InstanceID="066259d5-4c5a-4b1f-991f-0d839f105a68",Name="Migration",JobState=4,TimeOfLastStateChange,TimeBeforeRemoval=00000000000500.000000:000
Also, the output of gi with the lowercase notation as follows:
wbemcli gi http://root:password@localhost/root/virt:Virt_MigrationJob.
instanceid="066259d5-4c5a-4b1f-991f-0d839f105a68"
