Hi Guys,
Here is series that enable KVM in V8 BE image. It is addition on top of previously posted V7 BE KVM support [1].
It was tested on aarch64 fastmodels and APM mustang board. It was tested only with kvmtool at this point. In case of V8 BE KVM host was tested that V8 BE guest runs fine and V8 LE guest runs too. Also V8 LE KVM regression was tested on both V8 LE guest and V8 BE guest. Note for mixed mode Marc's kvmtool was used and guest image had minor change that treats all virtio in LE form.
Note first two patches are similar to V7 BE KVM patches. Last three are new specific for V8 image.
Thanks, Victor
