Hi Marcin & Johnny, 

Thanks for the reply. My requirement is to setup a VM with aarch64(64 bit arm architecture) on x86_64 host.

I have tried installing through virt-manager but i’m getting crash when starting the VM. I have attached the error below. In this, centos-7.2.img is built using virt-builder with lentos-7.2 for the aarch64. 

##qemu-system-arm -m 1024 -machine vexpress-a9    -drive file=centos-7.2.img,format=raw,if=ide

if i use virtio for the drive interface. i’m getting below error. 

##qemu-system-arm -m 1024 -machine vexpress-a9    -drive file=centos-7.2.img,format=raw,if=virtio

You can also follow this guide to install a 32 bit VM on an aarch64
host, if 32 bit arm is what you want to dev on:
