How to add ComputerName to rhevm-config?

Hi,

I am trying to fine tune our sysprep so the computername is set bij the rhevm.

VM-name = ComputerName

When I set Computername value I get the following error:

#rhevm-config --set ComputerName=Value
Error setting ComputerName's value. No such entry.

In %systemroot%\Panther\Unattendgc\Setupact.log I see an error:

ComputerName: failed to set computername [hr0x80070057][gle=0x00000057]

Can anyone help me.

We have RHEV 3.1

Best regards

Bart
