[PATCH 0/3] target/arm: Add nested virtualization support

[Haibo Xu]

This series add support for ARMv8.3/8.4 nested virtualization support
in KVM mode. It's based on Marc Zyngier's kernel KVM patches[1], and
has been tested on a FVP model to run a L2 guest with Qemu. Now the
feature can be enabled by "-M virt,accel=kvm,virtualization=on" when
starting a VM.
