Vmware Workstation "The parent virtual disk has been modified since the child was created."

Holy Crap!  The first error I got was "The specified virtual disk needs repair".  Vmware workstation was bitching about an upgrade to 7.1.1 so I allowed the update, because according to VMware's site, the 7.1.1 fixes that error --
"When a host system failure occurs during a virtual machine disk operation, attempting to power on the virtual machine or mount the virtual disk using the VMware Disk Mount utility causes the following error messages to appear, " Cannot open the disk... The specified virtual disk needs repair" and "Error reading volume information. Please select another disk file".  There is no data lost during this process. VMware Workstation 7.1.1 fixes these issues and enables virtual machine operations to resume."
(as noted in the second to the last paragraph on http://www.vmware.com/support/ws71/doc/releasenotes_ws711.html )

Now it says "The parent virtual disk has been modified since the child was created." when I try and launch my virtual server.

What can I do to fix this problem?  My business is down because we cannot access the server and they do not open for another 1.5 hours (6am-6pm Pacific time).

Any help would be greatly appreciated....

And does the disk in question have any snapshots ?

The link Alex posted above i.e http://driveactivated.com/blog/archive/2007/11/06/recovering-vmware-snapshot-after-parent-changed.aspx would seem to be the culprit if you have any snapshots on the disk.

It has at least 1 snapshot.  I see 2 files (vmem and vmsn) that end in "Snapshot4".

I am not following you on what type of disk.  Could you explain that a little more?

Well the virtual HD on your virtual machine can be fixed, dynamic or differencing (stores the difference from a parent disk). I just wanted some idea of what type it was. In general your problem is caused by when a snapshot becomes out of sync with the disk to which is references, or rather VMWARE believes it does.

The guide Alex and I posted should assist - at the very least its worth looking at.

There is a parent disk and a child disk with *000002.vmdk as the later part of the name.

From the links posted earlier I am trying to change the parentCID in the child disk to be in sync with the parent's CID.  It is taking forever to do because of the file sizes.

I am sorely tempted to make a simple app to make resetting the parentCIDs easier.

Why in the world doesn't Vmware have this already?  

I could not find the owner's info for the copy of vmware at the company where this is installed, so I went online and bought a license (to make sure they were legal and all) and I bought a single support session.  I called them over 8 hours ago and they took my info and said a tech would call me back.

If I fix it before they call, I am going to return the software for a refund and try and switch the client to VirtualBox instead.  If you are going to get no service, you may as well get it for free.

I have waited for over 10 hours for a return call from VMWare.  With the help of Experts Exchange, I fixed the problem without their help.

Seeing as how VirtualBox is free (and I was getting no support from Vmware) I called to request a refund.

First, the person on the phone asked for the support number, which I provided.  He said the reason I did not get a call was that the person that filed the request for support put it in as a non-paid request for support.  This was obviously wrong as I purchased the support this morning.

I asked for the refund.

VMware refused to issue a credit for the purchase.  The person on the phone said that they do not do refunds for "workstation".

I told them that I would have VISA reverse the charges if they refused to refund the purchase.

He said "That'd be one way to go."  So that's what I am doing first thing in the morning.

Maybe they should call it Bmware instead.

Just an FYI.....

Final post on the subject....

According to the EULA for Vmware Workstation on Vmware's site (http://www.wmware.com/download/eula/workstation7.html) "YOU MAY RETURN THE UNUSED SOFTWARE TO THE VENDOR FROM WHICH YOU ACQUIRED  IT WITHIN THIRTY (30) DAYS AND REQUEST A REFUND OF THE LICENSE FEE, IF  ANY, ALREADY PAID UPON SHOWING PROOF OF PAYMENT.  "

So, I should have been able to get a refund when I called and requested one.

VISA to the rescue!
