VMware workstation on Xensever VM

Hi,

I have a XenServer host test environment running version 5.6 FP1, inside it i have created a Windows Server 2003 64bit ENT Edition VM with 16VCPU/16GB RAM. On this VM i'm unable to install VMware workstation, it say's cannot install on Hyper-V.

Can we install VMware workstation on XenServer VM?

Thanks

Ro
