You are right, its a slightly dated system. x86info shows:

...
CPU #4
EFamily: 0 EModel: 0 Family: 15 Model: 4 Stepping: 1
CPU Model: Pentium 4 (Prescott) [E0]
Processor name string: Intel(R) Xeon(TM) CPU 3.60GHz
...

I need to move to another host, all of my systems lack EPT support.


Is there a portable way to check for the EPT flag in xenpaging?

Its just naive debug output.
