2.6.27 should be plenty fine for nx. Really the important bit is that
the host kernel has nx enabled. Can you check if that is so?
Umm, could you give me a clue about how to do that. It is some time
since I configured the host kernel, but I do have a /proc/config.gz.
Could I check by looking in that?
The attached script should verify it.
rs% ./check-nx
Traceback (most recent call last):
File "./check-nx", line 17, in<module>
efer = msr().read(0xc0000080, 0)

self.f = file('/dev/msr0')
IOError: [Errno 2] No such file or directory: '/dev/msr0'
Run as root, please. And check first that you have a file named
/dev/cpu/0/msr.
