Hi all
I wonder if there''s any way that I can do nested xen on domU not dom0.
This is what I plan.
| dom0_T| |domU1_T| |domU2_T|
----------------------------- (domU1_B)
|dom0_B| | xen top |
-----------------------------------------
| xen bottom |
And I want to be able to take the entire snapshot of domU1_B (including dom0_T,
domU1_T, domU2_T)
So far, only documents I found about nested xen told me to install the xen top
on dom0_B.
So I wonder if there''s any way to install xen top on domU1_B or any
workaround.
Thanks,
- Hyo

You should e aware that the feature is still experimental, and performance will not be so great (but better on AMD than on Intel).

Cc''ing the author and maintainer of the Intel nested-HVM code. Eddie, can you help please? Is this meant to work?
