I don't quite follow your question. However if you are asking about the cross-architecture emulation (usually called TCG) the features of the processor depend on how complete the front-end is. So you can for example boot an aarch64 system under emulation that can itself run KVM guests (because we implement EL0/1/2/3). However you the system can't currently use VHE extensions because the support for that has yet to be added. What is your use-case? -- Alex Benn=C3=A9e
