Yes, we've made several automated test cases for Nested VMX.
The bad news is there's some bug on Nested VMX.
>From my recent test, the following is the status for Nested VMX.
   Xen on Xen: failed. L1 Xen guest can't boot up. It hangs at the boot for xen 
hypervisor.
   KVM on Xen: pass. L2 RHEL5.5 guest can boot up on L1 KVM guest.
(We use the same version of dom0 and xen-unstable as mentioned in the report.)
Intel will make more effort on Nested VMX bug fixing this year.
