KVM on arm64 with kvm tools

[Antonios Motakis <a.motakis@xxxxxxxxxxxxxxxxxxxxxx>]

Hello,

I have an aarch64 kernel running on the foundation model which includes KVM from Marc's repository (latest kvm-arm64/kvm). I also use kvm tools from Will's latest kvmtool/next. However trying to get a Linux image to run in the guest does not seem to produce any console output from the guest, despite having enabled virtio console in the kernel config.

The only output is:

root@genericarmv8:~# ./lkvm run -k Image -m 128 -c 1 --console virtio
  # lkvm run -k Image -m 128 -c 1 --name guest-569
  Warning: Image is not a bzImage. Trying to load it as a flat binary...
  Info: Loaded kernel to 0x80080000 (6668324 bytes)
  Info: Placing fdt at 0x87e00000 - 0x87ffffff
  Warning: Ignoring invalid GIC IRQ 4
  Warning: Ignoring invalid GIC IRQ 3
  Warning: Ignoring invalid GIC IRQ 4
  Warning: Ignoring invalid GIC IRQ 3
  Info: virtio-mmio.devices=0x200@0x0:32

  Info: virtio-mmio.devices=0x200@0x200:33

  Info: virtio-mmio.devices=0x200@0x400:35

And then silence.

I attach the .config file I'm using for both the host and guest kernel. I would also appreciate if I can borrow a working .config from someone so I may narrow down if my issue is due to my guest config, or something else.

Best regards,
