Hi Cam,
I used your patches successfully to support shared memory on KVM and
used the test cases successfully, but qemu-kvm crashes when I increased the
size of the shared memory. I
applied the ivshmem patch to qemu-kvm-0.12.3 (some manual patching was
needed). It worked flawlessly for

This patch:
- Makes kvm_config use less memory during parsing, by storing config data
compactly in arrays during parsing, and generating the final dicts only when
requested.
On my machine this results in 5-10 times less memory being used (depending on
the size of the final generated list).

Because I suspect Ingo, like me, is a command line user, launching a gui
to start kvm when there is a kvm command around just sounds daft.
Hi,
Thanks for the reply. I have a Intel Q9550 processor. EPT was
introduced in the Nehalem series, where my processor is not part of.
Based on that, I conclude that I am not using EPT and thus using
shadow page tables.
