"tilt up" from hello-world leads to "libva error"

[yogeek]

Expected Behavior

the Hello world tutorial has no error

Current Behavior

Following the instructions here :

• tilt up
• "Create a starter Tiltfile ?" => no
• "space" to open browser => error :

$ tilt up
Starting Tilt...

Tilt started on http://localhost:10350/
v0.27.3, built 2022-04-22

(space) to open the browser
(s) to stream logs (--stream=true)
(t) to open legacy terminal mode (--legacy=true)
(ctrl-c) to exit
Opening browser: http://localhost:10350/
Opening in existing browser session.

About Your Use Case

Just trying to evaluate Tilt

😱

Sorry to hear about that @yogeek .

Can you run

xdg-open https://github.com/

from the command-line? What happens?

That message usually means you have your default browser badly misconfigured on linux. You can also open the tilt web ui directly at http://localhost:10350/

@nicks thanks for your help.

xdg-open https://github.com opens chrome on github page, but in the terminal, it outputs the same error message

libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
[61003:61003:0100/000000.359207:ERROR:sandbox_linux.cc(377)] InitializeSandbox() called with multiple threads in process gpu-process.

the problem, is that, with tilt, the browser also opens automatically event with the error message, but the page http://localhost:10350 displays This site can’t be reached error message

so finally, I think i have 2 issues : one with my local environment which causes the error message but does not prevent the browser to open, and the one with tilt because i cannot see anything on the web page (localhost:10350)

Note : my environment is a virtualbox ubuntu VM

I found this github issue - intel/libva#278 - but TBH it's a bit beyond me.

Ya, if you're running tilt in an ubuntu VM, you have to open Tilt's dashboard on the VM's localhost, not the host machine localhost.

One way to do this is to run the browser in the VM.

Another way is to start tilt with tilt up --host 0.0.0.0, so you can access it from the host machine at http://[static VM IP Address]:10350/, similar to how you would access any other server running in the VM.

@nicks yes I was already using the brower inside the VM, so my localhost is the localhost of the VM

But the --host 0.0.0.0 solved the problem indeed : now it is working correctly !
Thank you for your help !

FYI, I checked to try to understand the difference between both command, and it seems to be the URL exposed by tilt by default :

tilt up => expose "localhost" and does not work on my VM

tilt up               
Tilt started on http://localhost:10350/

tilt up --host 0.0.0.0 => expose 127.0.0.1 and works on my VM

tilt up --host 0.0.0.0
Tilt started on http://127.0.0.1:10350/ (listening on 0.0.0.0)

Anyway thanks, i can continue my evaluation ;)

yay! ya, VM networking is odd. closing...
