[Remote-SSH Bug]: Trying to connect to x86-64 Lima VM on ARM macOS host via Remote-SSH throws `std::bad_alloc` when attempting to start VS Code server #8391

cpolish · 2023-04-20T01:33:22Z

Is there an existing issue for this bug?

I have searched the existing issues

Required Troubleshooting Steps

I have followed these troubleshooting steps
I have tried both values of the remote.SSH.useLocalServer setting

Connect Locally

It connects successfully

->

No response

Expected Behavior

The Remote-SSH extension should be able to connect to the running Lima VM instance, and install and run the VS Code server successfully.

Steps To Reproduce

Create a Lima instance on an ARM macOS host, using QEMU for the virtualisation type, and 9p for the filesystem mount type.
Include Lima's SSH config file in the user's SSH config file.
Use the Remote-SSH extension to remotely to connect to the VM via SSH.
After connecting, VS Code will install and attempt to run the VS Code server multiple times, but will fail: the final Remote-SSH output messages indicate Failed to set up socket for dynamic port forward to remote port <port>: Socket closed. Is the remote port correct?.
In the VM, upon inspecting ~/.vscode-server/.<hash>.log, the log mentions the server terminating after throwing an instance of 'std::bad_alloc'.
In the VM, attempting to manually run ~/.vscode-server/bin/<hash>/out/server-main.js will result in the same exception being thrown.

I'm not sure of the exact cause of this, whether it could be the architecture, or something else, as there doesn't seem to be much information online regarding this issue with the Remote-SSH extension.

Is it possible that your VM is out of memory?

Any idea @deepak1556?

cpolish · 2023-04-21T14:09:36Z

Hi, thanks for getting back. I've had a look at my VM's memory using top inside the VM, and in terms of memory usage, it should be OK (the VM has 4 GB of memory allocated to it, with ≈2.4 GB free). I've also tried splitting the terminal using tmux, and monitoring the memory usage using top in one pane, whilst running ./server.sh in the other pane (for the VS Code Server), but unfortunately, no dice: memory usage is stable, and it seems that the std::bad_alloc exception is thrown.

dsheng123 · 2023-05-15T19:52:48Z

I have the same issue as far as I can guess on Colima and also on lima directly. In my case I am trying to run a dotnet docker container on a x86_64 lima VM.

The same setup worked on the vz branch in December 2022 on an M1 Pro. So did anything change between now and then and does the CPU (now M2 Max) make a difference?

Does anyone have any idea?

KuttKatrea · 2023-05-15T21:22:17Z

I noted a similar error when running mongosh also on Colima and Lima. It seems has something to do between qemu and node, as both tools are based on it, but I haven't been able to pinpoint the problem or a combination of versions that work.

deepak1556 · 2023-05-16T08:31:54Z

Are you able to run Node.js https://nodejs.org/download/release/v16.17.1/ on this VM ?

KuttKatrea · 2023-05-17T22:00:11Z

In fact, I can't

Also, it seems there is already a ticket on NodeJS for this issue:

deepak1556 · 2023-05-17T23:53:44Z

Thanks for confirming! We would have to wait for the upstream issue to be resolved. Can you try with docker instead, upstream issue seems to report it to be resolved there.

josecanciani · 2023-05-22T19:56:49Z

Also found same problem reported here: nodejs/help#4156

My case is similar, $ node show the same error, running on a Mac M1 qemu server, emulating a x86 Ubuntu emulation, with an Ubuntu guest and an old 10.x version of node. So it seems to indicate this is a node/qemu issue, rather than a vscode problem.

I repeated this test on QEMU 8.0.3 and it seemed to work just fine.

Maybe this was resolved on QEMU's side?

seonglae · 2023-10-11T07:33:14Z

@KuttKatrea My QEMU version is 8.1.1 and I'm still this experience this issue. Not sure about your Mac OS version tho, according to this thread lima-vm/lima#1605, This error might happens after MacOS 13.4 (mine is Mac 14.0)
