Hi all,
I'm seeing some breakage of shadow-on-shadow and shadow-on-EPT nested
VMX. Until I can track more precisely whether it is a regression, and
on which hosts I can reproduce it, I'm going to leave the patches out of
kvm/next.
The good news is that nested EPT works pretty well. :)
Paolo

Paolo/others, I'm trying to test nEPT, so I'm trying to start this way:
$ git clone git://git.kernel.org/pub/scm/virt/kvm/kvm.git
$ git branch --all
$ git checkout remotes/origin/queue
Compile, and proceed.
Or would you suggest to use
http://git.kiszka.org/?p=kvm-kmod.git;a=blob;f=README
to test latest stuff?
Thanks.

If you prefer not to build your own kernel, kvm-kmod works too.
However, please build it with the latest 3.10.x kernel to make the
environment as similar as possible to what you'd get with kvm.git.

I'm fine building news Kernels. I just started this way:
$ git remote -v
origin git://git.kernel.org/pub/scm/virt/kvm/kvm.git (fetch)
origin git://git.kernel.org/pub/scm/virt/kvm/kvm.git (push)
$ git checkout -b test_nept origin/queue
$ make defconfig
$ make -j8 && make modules
$ make install && make modules_install
And, booting into the just built 3.11.0-rc1+ kernel (this is on
bare-metal), hangs at:
-------------
.
.
.
[ 5.437220] systemd[1]: Failed to mount /dev: No such device

(This is on a Haswell machine).
Am I missing anything here?

After that, it goes one step beyond after the above, and gets hung at:
---

Yeah, shadow-on-EPT doesn't work on at least the Westmere I tried, so
I'll merge kvm/queue to kvm/next soon.
