Re: [Qemu-arm] Arm Cortex A-72 Emulator not able to configure

Hi Peter, 

I have tried the blog post which you shared but i’m getting some error as Virt type not supported. 

qemu-system-arm -M virt -m 1024 -cpu cortex-a53   -kernel installer-linux   -initrd installer-initrd.gz   -drive if=none,file=hda.qcow2,format=qcow2,id=hd   -device virtio-blk-pci,drive=hd   -netdev user,id=mynet   -device virtio-net-pci,netdev=mynet   -nographic -no-reboot

(process:3246): GLib-WARNING **: gmem.c:483: custom memory allocation vtable not supported

qemu-system-arm: mach-virt: CPU cortex-a53 not supported

Some times i’m getting error as pic-virtio device not supported. 

I would give some picture on what i’m trying to achieve. 

I have a host with CentOS 7 (x86 arch) and in that i have install Qemu and KVM. In this server, I’m trying to install a VM with Arm64 and setup a development environment for ARM. 

Regards, 

Karthi

Hi All,

I’m new to Qemu Environment. I was trying to setup a Arm (64 bit) emulator
for getting hands-on and need to setup an development environment. I was
not able to find any document or any working article for setting up
the ARM Emulator using KVM. Can someone help me to point in right direction to proceed?

To use KVM on an Arm host you should just be able to pass
"-cpu host -enable-kvm" instead of "-cpu cortex-53" (by
default it will use emulation, which will work but be slower).

can this be achieved in Nested Virtualization?

You'll need to be clearer about what you mean here, but in general
nested virt is not yet implemented for arm hosts.

thanks
