Unable to perform the job because…SCVMM 2008 R2 Error 2606

I was trying to do a V2V conversion using SCVMM 2008 R2, and during the conversion I canceled the job. Then the hell came over me, I could not remove the virtual machine from the host any more using VMM console.

I was keep getting the same error message:

Error (2606)
Unable to perform the job because one or more of the selected objects are locked by another job.

Recommended Action
To find out which job is locking the object, in the Jobs view, group by Status, and find the running or canceling job for the object. When the job is complete, try again. 

Here is a print screen with the error:

I tried forcing it with PowerShell, I rebooted the server, but nothing, so as a last resort I logged in on the Hyper-V host and deleted the virtual machine from here. Then I went back to the VMM server, removed the host from the console and re-added back in. It worked, my “half” virtual machine was gone now.
