Re: [Ovirt-devel] Question about ovirt migration



Hi, Chris

Thank you for your description.

Then I want to understand the software layer for *fake* managed node.
But, Nested KVM does not support at this moment.(Ref)
Would you point the code of guest boot on fake managed node?

Ref.
[PATCH 0/9] [RFC] Add support for nested SVM (kernel)
http://thread.gmane.org/gmane.comp.emulators.kvm.devel/21119

Thanks
