Re: [Xen-users] VMWare vs. Xen, is the conflict by VMware deliberate?
VMware supports hardware virtualization.
VMware supported VMX (Intel Silicon virtualization) before Xen did, it was the first product to launch with commercial support for hardware virtualization.
ALL VMware products, including their FREE products support CPU and memory virtualization. Running VMware on top of Xen is redundant.

VMware requires that your host kernel be run in ring 0 (to do cpu
scheduling, memory management and provide timer interrupts) where as in xen architecture hypervisor has taken ring 0 and deprivileged the guest kernel (dom0 kernel) to other rings. So running VMware on dom0 doesn't
allow it to virtualize cpu, memory. My 2 cents
