After blogging about moving virtual machines from a standard virtual switch to a distributed virtual switch, I saw a new question in VI Java API forum on how to roll it back. Technically, I don’t see any reason why one should switch back because using distributed virtual switch gives you a lot of benefits. But the decision is not mine but yours. Whatever you want to do, we help do it easily.

The method involved is still the ReconfigVM_Task() defined with VirtualMachine managed object. The difference comes with the parameter, mainly the backing. When it comes to Web Service API, it’s better to show either code or SOAP message. To me, SOAP message is even better because you can reference it even using toolkit like PowerCLI.

The following is recorded with Onyx. Based on this SOAP request, I think you can easily write code to achieve the same.

<soap:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
