Virtual device not starting

Vega Open Beta Bug Reports

:backhand_index_pointing_right: Bug Description

1. Summary

After installing and configuring everything, I wanted to test the development environment using the hello world template.

Once I “installed” the template, I tried running the VirtualDevice:Tv, but after around 1 min, it crashes with the following message:

App Name: N/A
App Link on Amazon Appstore N/A

Bug Severity
Select one that applies

  • Impacts the development of the app ← can’t select it

2. Steps to Reproduce

  1. Follow the steps to install vega and its dependencies Install the Vega SDK | Vega Get Started
  2. Follow the steps to create a hello world app from the template Create a Hello World App | Vega Get Started
  3. Try to launch this app using the VVD

3. Observed Behavior

Explain what actually happened, noting any discrepancies or malfunctions.

Once everything was set up, I tried running the VirtualDevice:Tv from vsCode, using the Vega Estudio extension. After pressing the play button, it shows the screen with the kepler virtual device in black.

After around 1 min, it crashes with the following message in vsCode Console:

[warning] kepler operation FAILED due to an irrecoverable error: The virtual device failed to start within the expected time.

Tried troubleshooting using the provided common issues in the documentation (ADDED the parameter to increase the timeout to 1000, and still failed)

None of the options provided works.

4. Expected Behavior

Describe what you expected the SDK to do under normal operation.

It should run the application just as the example shows

4.a Possible Root Cause & Temporary Workaround

Fill out anything you have tried. If you don’t know, N/A is acceptable

6. Environment

Please fill out the fields related to your bug below:

  • SDK Version: Output of kepler --version 0.21.4726

  • App State: [Foreground/Background]

  • OS Information
    Please ssh into the device via kepler exec vda shelland copy the output from cat /etc/os-releaseinto the answer section below. Note, if you don’t have a simulator running or device attached kepler exec vda shell will respond with vda: no devices/emulators found

    No device running, this is exactly why I'm reporting, it doesn't run.

7. Example Code Snippet / Screenshots / Screengrabs

Include any relevant code or component setup in React Native that can help reproduce the bug.

N/A is the same template for hello world

Hi @Yorki_Bonilla,

Welcome to the community!

Would you be able to provide more information about this issue?

  • Once Vega Virtual Device gets started, it should show a screen like below (with a text saying that it is ready). Please share a screenshot if your observation is different.

  • Share the content of ‘Output’ window from VS code when the output source is ‘Kepler’
  • Share contents of virtual_device.err and virtual_device.out files from the path ~/kepler/sdk/0.21.4726/kvd/instances/<instance-id>?
  • Check troubleshooting options from this page and share your observations

Regards,

I already tried all the steps on this page, but it didn’t work:

1: Tried to launch without any dockings or USB connected
2: I completely removed audio from the virtual machine
3: Tried running the virtual device by console, increasing its load time with the –timeout parameter set to 1000

Ok, solved my issue… problem?

Virtual device was not starting

Solution?

Started over with a totally new virtual machine, made sure to install everything correctly, and it failed at the same spot.

After that I found the solution online and after following it, it works just fine.

I’m using windows 10 as my main OS
I’m using vmware to virtualize Ubuntu 22.04.5

After installing everything according to the vega docs, I had to do this extra step:

#region disable hypervisor on windows host

/* https://www.youtube.com/watch?v=6f1Qckg2Zx0

run this in the cmd as administrator

bcdedit /set hypervisorlaunchtype off

Run this in power shell as administrator:

Disable-WindowsOptionalFeature -Online -FeatureName HypervisorPlatform
