vfkit exited unexpectedly (invalid virtual machine configuration)

[alechenninger]

Issue Description

podman machine init fails with "vfkit exited unexpectedly with exit code 1"

Steps to reproduce the issue

Steps to reproduce the issue

1. Run podman machine init --cpus 6 -m 3072 -v $(pwd):$(pwd) --now

Based on the error below, I'm assuming this requires the working directory to be a long path (mine is /Users/ahenning/Code/alechenninger.com/macro-server/ps4disasm).

podman machine init fails with "vfkit exited unexpectedly with exit code 1"

I tried to run gvproxy and vfkit directly using debug output as another contributor had done to see the error and work around the issue. It appears this may be related to the mount. When running vfkit directly, using the command from podman's debug output, I get:

Error Domain=VZErrorDomain Code=2 Description="Invalid virtual machine configuration. The Virtio file system device “tag” cannot exceed 36 bytes when encoded in UTF-8. The tag “Users-ahenning-Code-alechenninger.com-macro-server-ps4disasm” is invalid" UserInfo={
    NSLocalizedFailure = "Invalid virtual machine configuration.";
    NSLocalizedFailureReason = "The Virtio file system device \U201ctag\U201d cannot exceed 36 bytes when encoded in UTF-8. The tag \U201cUsers-ahenning-Code-alechenninger.com-macro-server-ps4disasm\U201d is invalid";
}

The command I ran was:

Describe the results you expected

I expected the VM to start.

I just downgraded podman to 4.9.4 so I don't have this. But I had just upgraded to 5, and am running macOS 14.4

@cfergeau is this coming out of the hypervisor? im not seeing the error message in vfkit or otherwise?

Yes, this would be coming out of Apple Virtualization Framework (NSLocalizedFailure is coming from objective-c code)

[cfergeau]

This can be reproduced with this vfkit argument: --device virtio-fs,sharedDir=/Users/teuf/dev,mountTag=AbcdefghijklmnopqrstuvwxyzAbcdefghijklmnopqrstuvwxyz

I am also experiencing this issue. Here is what I think is the relevant debug text from CLI (I added newlines to help finding the sharedDir configs:

When can we expect #22288 to be merged and fixed in brew?
Is there a way to force use of qemu to work around the bug for now, or do I need to downgrade my podman version?

[ebarrere]

I also need this fix. The only reason I use different machines is to separate code paths, so all of them are going to be longer than 36 characters...
