2 last questions:

a) i remember that there (have been) are instructions that have a high
virtualization penalty.
are there flags that should better not be offered to a VM?

b) you told you fixed another bug in 2.6.35. is the nx virtualization
not working in guests
before 2.6.35 and therefore my case worked with 2.6.34?

thanks
