Running Workstation 10 inside Parallels 9

Hi,

I need to run workstation 10 inside Parallels 9 for MAC.

I was able to create the vm, but when I power on the vm, i get the following error message from workstation:

"You are running VMware Workstation through an incompatible hypervisor. You cannot power on a virtual machine until this hypervisor is disabled".

Since I cannot run Workstation 10 directly on my MacBook, is there any workaround you can suggest?

Thank you

Pascale
