I have an old laptop I'm trying to create a VM image from. I'm using the latest version of the VMware Converter app.

The machine is an Intel Core Duo with 1GB of RAM running WinXP Pro.

When I get to the "View/Edit Options" step in VMWare Converter there's a warning next to Memory. The warning states:

The memory allocated for the destination machine has been set to the maximum supported for the guest operating system by the target host. The allocated memory is less than the source memory setting.

It shows that the maximum amount of memory I can allocate is 880MB.

What does this error mean? Why would the converter be restricting me to 880MB of RAM? I know VMWare can handle more than that, as can WinXP.

You can't allocate more then 70% of physical memory to a virtual machine. Virtual Machine managers will give a warning since this will not leave enough physical memory for the host machine to run.

Virtual Machines are only allocated physical memory.

PS: The 70% I can't confirm at the moment but this has been my experience with most virtual machine managers. Hyper-V allows 80% on HyperVisor but only 60% when running on a full version of Server 2008. Others only allow up to 50% for example.

In your case the VM itself will be created as if you will be running it on the same machine acting as host.

Edit: The VM can still be created using the specified memory size. It is a warning only that the virtual machine may not run on that particular machine. I am not sure if this has changed in the newer VMWare converter.

The amount of memory assigned to the VM can be changed later, but I think that you already figured it out :).

I solved the blue screen issues after converting a physical machine to a virtual one by changing the virtual disk adapter from IDE to SCSI.

HTH!
