VVD stuck on firetv logo

[Laurice_dela_Cruz]

Tried running the Vega Virtual Device. Terminal says “Virtual device ready” but VVD is just showing the FireTV logo. How to fix this?

I am using MacBook Pro(Intel), macOS Sonoma

Hi @Laurice_dela_Cruz,

Welcome to the Amazon Developer Community!

Thank you for reporting the VVD stuck on FireTV logo issue. Our team is investigating this issue and will provide an update as soon as we have more information.

In the meantime, please try this:

1. Stop the virtual device: kepler virtual-device stop

2. Wait 10 seconds

3. Start fresh: kepler virtual-device start

4. Wait 30-60 seconds for boot completion

5. Verify: kepler device list

This will delete the existing VVD state and create a fresh instance, which often resolves boot issues.

Thanks for helping us improve the Vega platform.

Warm regards,
Aishwarya

Hello Laurice,

The long boot time issue you are experiencing can be caused by multiple factors. In order to better understand the root cause, we would need some additional information about your environment.

As a first step, please try increasing the timeout for the Kepler Virtual Device startup process to allow more time for the virtual device to complete the boot sequence before the process is terminated. You can do this by following the documentation below:

https://developer.amazon.com/docs/kepler-tv/kepler-virtual-device.html#start-the-kepler-virtual-device

kepler device simulator start --timeout 600

If this still fails, it is possible that the virtual device instance was corrupted during creation. In that case, please delete the following directory and try starting the virtual device again:

/Users/<username>/kepler/sdk/<version>/kvd/instances/<random-hash>/

If the problem persists, could you please share the following information with us:

• The full console output you receive.

• The virtual_device.err and virtual_device.out files located under the instance folder:

/Users/<username>/kepler/sdk/<version>/kvd/instances/<random-hash>/

This information will help us further investigate the issue.

Best regards,

[Laurice_dela_Cruz]

I tried increasing the timeout and deleting the virtual device instance and creating new one but it is still stuck on firetv logo.

Hi Laurice,

We’ve been trying to reproduce your issue in a similar environment, but the Virtual Device runs correctly on our side. This suggests that the problem may be environment-specific.

Unfortunately, the stdout and stderr files you shared didn’t provide enough information to identify the root cause. Could you please run the following commands so we can better understand what might be happening on your end? Please share the output of each one.

1. Start the Virtual Device:

kepler device simulator start --timeout 800

2. In a separate terminal, run:

vda devices
vda shell systemctl list-jobs
vda shell systemd-analyze

3. Then extract the logs from inside the Virtual Device:

vda shell journalctl -f > logs.txt

Please press Ctrl + C when you want to stop the log collection.
This will generate a logs.txt file—could you share that file with us?

Thank you!
