mount a read-only vmdk

Hi!

 

How can I (read-only) mount a read-only vmdk with vmware-mount?

 

More details:

I have a read-only nfs-export, where 40 GB .vmdks are inside. When I try to mount them with vmware-mount from the vddk, it requests write access to the .vmdk.

 

Things I already tried:

  • A possible solution would be to copy the vmdk to a local disk, which I try to avoid for performance reasons.
  • Another solution I thought about was to create a unionfs or aufs over the nfs-share. However, the problem is that unionfs/aufs tries to copy the whole file when the first write access is done (does not work on changed blocks).
  • A third solution I thought of was to create a diff-VM but this would mean that I need to boot a VM just for mounting the files…
