Can I run cuttlefish Arm64 on x86 PC?

[Lawrence Lin]

Dear all,

I follow the steps on the cuttlefish intro. page, "https://android.googlesource.com/device/google/cuttlefish/"

I can run the aosp_cf_x86_phone sku on PC (x86)

And I try to build the image "aosp_cf_arm64_phone-userdebug" sku from the AOSP codebase 

But I can not boot up the VM by same way.

Please give me some help, I want to run the ARM vm on x86 PC.

many thanks

My understanding is that cuttlefish's arm[64] variant is meant to run on an arm64 machine, not an x86 machine.
