0.4.0 aarch64 image hangs on Debian 10 host

[xinliang]

Host:
Debian10
qemu-efi: 0~20181115.85588389-3
qemu-system-aarch64: QEMU emulator version 3.1.0 (Debian 1:3.1+dfsg-8+deb10u3)
libvirt: 5.0.0

Reproduce:
$ cd /tmp/; wget -c http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-aarch64-disk.img
$ virt-install \

  --boot uefi \
  --network bridge=docker0 \
  --disk /tmp/cirros-0.4.0-aarch64-disk.img \
  --import

After seeing the grub boot entry, adding kernel param "earlycon=pl011,0x9000000" will see bellow hangs log:

Cirros is very small and is a good image to test openstack, such as refstack tests.
This issue blocks the users to use it to do such tests.

The problem might be switching dtb booting from acpi. We had tested it can boot on debian9 host before.
If I don't remember wrong, it boot from dtb on debian9.

I have tested ubuntu-18.04.3 cloud image (with higher version kernel 4.15.0-72-generic) on aarch64, it works fine.

Hoping there is a new version of cirros image built with newer kernel. Because older kernel might not support aarch64 acpi well.

I am glad to help to do such work. But I don't know how to do yet.

Fails also with 'acpi=off' kernel argument.

Cirros daily with kernel/grub from Ubuntu 18.04 boots fine.

[Jonathan Rosser (jrosser)]

For openstack-ansible we did a ton of work on Cirros for Arm and fixed it up quite a bit though i'm not sure this ever got further than a 'contrib' build.

See https://github.com/openstack/openstack-ansible-os_tempest/blob/0f4570ec2be4af4f55da95c5028bfd965ea680d2/vars/main.yml#L32-L38

virtio_gpu module needs to be added to rootfs.

[Marcin Juszkiewicz (hrw)]

With virtio-gpu added console output goes to serial port anyway.

https://github.com/hrw/cirros/releases/tag/hrw_0.5.0_pre2_18.04hwe has images with 18.04-hwe (5.0) kernels.

Please test.
