Cuttlefish Android failed to start

[Qinglin Li]

Hello, everyone.
I'm using cuttlefish android and I'm getting errors when running it, the key issue seems to be an error in crosvm，My operating system is Ubuntu 24.04.

The logs are shown below:

This is probably a question for cuttlefish folks at cloud-an...@google.com

Anyone has any ideas?

This error sounds like some device process failed during init, but it doesn't really say which one:

`failed to create a PCI root hub: failed to create proxy device: Failed to configure tube: failed to receive packet: Connection reset by peer (os error 104)`

Maybe caused by this earlier issue? `unshare(CLONE_NEWNS) failed: Operation not permitted`, which I suspect means the seccomp policy is missing an entry?

That error is inside minijail_enter. Seems like you don't have enough permissions to setup the sandboxing. If it is acceptable for you, you could disable sandboxing by passing `--enable-sandbox=false` to `launch_cvd` (or `cvd start`)

Does anyone have any solution that can help?

[Mikko Koivisto]

Try fixing this first

Too many open files (os error 24)

(https://ploi.io/documentation/server/how-do-i-fix-the-too-many-open-files-error)

Then this error is probably just because crosvm is not running and there is no vsocks between host and guest

webRTC E 09-07 10:49:19 11671 11967 vsock_connection.cpp:222] Failed to connect:No such device

Rest of the WebRTC errors are more about networking and seems that WebRTC is unable to connect to STUN server but that has nothing to do with crosvm.

Thank you, fixing that error enabled me to launch the device
