IO Limit Disks Bug?

Hello,

I've a script that limits disks io of all VMs. With upgrade to 5.5 Ux, that doesn'nt work anymore.

my $io_alloc = StorageIOAllocationInfo->new (shares => $sharesInfo, limit=> "10");

$device->storageIOAllocation ($io_alloc);

my $virtualDeviceConfigSpec = VirtualDeviceConfigSpec->new (device => $device, operation => VirtualDeviceConfigSpecOperation->new('edit'));

my $vmConfig = VirtualMachineConfigSpec->new (deviceChange => [$virtualDeviceConfigSpec]);

$vm->ReconfigVM (spec => $vmConfig);

I'm getting the following error:

SOAP Fault:

-----------

Fault string: Ein angegebener Parameter war nicht korrekt.

spec.sharesInfo.limit

Why is there any problem with shares?

I think that's a bug. Now I'm unable to set the disk io limit.

Any ideas, tricks oder workarounds?

Thanks!

Regards,
Alex
