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

Yes, this is exactly how nested HVM is meant to work. You should e
aware that the feature is still experimental, and performance will not
be so great (but better on AMD than on Intel).

I tried this recently on an Intel platform and was unable to bring up
DomU1_T. The bios screen wouldn't come up. Do let me know if you have better
luck.

ISTR that the last time I tried it I ended up using KVM as the nested
hypervisor (for other reasons).
Cc'ing the author and maintainer of the Intel nested-HVM code.
Eddie, can you help please? Is this meant to work?
Tim.
