"One of the parameters was invalid" while performing guest operations posted: Aug 20, 2008 11:03 AM

I have an application that copies files to a VM Image, runs and applications, and then copies the result files back.

The application loops through several configurations, at the begining of the loop it connects to a Server and opens a connection to an image.

At the end of the loop it closes the connection to the Server.

The application gets through 3 iterations just fine, but during the 4th interations it get "One of the parameters was invalid" whild performing guest operations.

At first I thought it was not getting a connection to the Image because it was happening before the first copy, but I do not get the message telling me that the application was not logged in.

I tried increasing the wait time for VMTools incase it wasn't waiting long enough and now it will begin coping files but fails after copying a few files.

I would just put in a check to see if the result file was copied back, but the application crashes when it attempts to revert the image.

What VMware product are you using?

What version of the VIX API?

I am using VIX 1.5 and VMWare Server 1.0.1

I am also working on a wrapper for ESXi, but there is currently no plans to convert all the servers over to ESxi.

I reworked one of my methods, minimizing the number of times that I tried to create a directory with a batch file and now it doesn't crash any more; so maybe I was destabalizing the image.

Hi,

I am getting the same error. My code just power on the virtual machine, loggin and then run a program in a virtual machine.

I use 2 webservices, one is published in a server, the other is published in some PCs with VMWare Server installed.

So I can with the server webservice manipulate the virtual machines in the differents PCs throught the webservice on it.

Some times runs sucessfull, other does not. And does not crash in the same line neither.

I am usin VMWare Server 2.0 and vestris API versio 1.6.

Anybody can help me about it?

Thanks in adavance

I think you're hitting the VIXCOM 1.6 bugs. You might be able to work around them by setting all objects that are unused to null and garbage collecting at the right places, but it's a painful process. Upgrading would help you, especially with the next VMWareTasks 1.4, I think I managed to wrap all the crash scenarios within the library so you don't have to worry about it.
