Hi!
This patch series brings Nested Virtualization to Xen.
This is the seventh patch series. Improvements to the
previous patch submission:
- Worked on all items from Tim
- Dropped vram patch
- Rebased against c/s 22573:ff1b80ccecd9
The patch series:
patch 01: add nestedhvm guest config option to the tools.
This is the only one patch touching the tools
patch 02: Add data structures for nested virtualization.
patch 03: add nestedhvm function hooks.
patch 04: The heart of nested virtualization.
patch 05: Allow switch to paged real mode during vmrun emulation.
Emulate cr0 and cr4 when guest does not intercept them
(i.e. Hyper-V/Windows7, KVM)
patch 06: When injecting an exception into nested guest, inject
#VMEXIT into the guest if intercepted.
patch 07: Allow guest to enable SVM in EFER only on AMD.
patch 08: Handle interrupts (generic part).
patch 09: SVM specific implementation for nested virtualization.
patch 10: Handle interrupts (SVM specific).
patch 11: The piece of code that effectively turns on nested virtualization.
patch 12: Handle nested pagefault to enable hap-on-hap and handle
nested guest page-table-walks to emulate instructions
the guest does not intercept (i.e. WBINVD with Windows 7).

Thanks for this. I've commented on patch 4 (core) and patch 12
(hap-on-hap) separately. Also I think we need an Acked-by: from Eddie
for patches 1-8.
Apart from that I think we can check these in as soon as the 4.1
branch has been taken, and fix up any remaining issues in-tree.
Cheers,
Tim.

When is the 4.1 branch planned to happen?

We usually do the branch just before release. So that would be about 6 weeks
I guess.

I am surprised about that. Did I miss the feature freeze announcement?

Proposed it back in November:

Good progress! Though in very details, there is maybe minor difference, but I vote we start to take the patches so that the next rebase and review can be easier :)
Even we can fix later on for those minor issue like other patches did in the past.

Patches 1-8 also need an explicit Ack from Eddie Dong.
Patch 12 I'll send comments on separately.
Cheers,
