Hi,
I'm a German student, writing my thesis on "Virtualization with Xen.
Analysis and Comparision of Different Techniques such as
Paravirtualization, Full Virtualization, and Utilization of Hardware
Support Provided by the Processor".
I'd like to know how I can disable HAP/RVI/Nested Paging for
benchmarking purposes. I read somewhere
(http://markmail.org/message/bbnivuqx6vjz7jg4) that Xen developers
decided to disable the global grub parameter introducing a per domain
flag for HAP instead (hap=0/1).
There's no way to set this per domain in libvirt. IMHO it was crazy
to remove the global boot parameter for it :-(
On the other hand, XenD is all python code so trivially modified. So you
could easily edit the XenD python code to turn HAP on/off globally when
running your benchmarking tests.

Daniel
