Rancher Desktop fails to find cached kubernetes version

[IsaSih]

Actual Behavior

lima fails to start the application with a combination of experimental settings, as the following:

"experimental": {
    "virtualMachine": {
      "type": "qemu",
      "useRosetta": false,
      "socketVMNet": false,
      "mount": {
        "type": "9p",
        "9p": {
          "securityModel": "mapped-xattr",
          "protocolVersion": "9p2000",
          "msizeInKib": 4,
          "cacheMode": "loose"
        }

Steps to Reproduce

1. Start Rancher Desktop
2. Go to Preferences > Virtual Machine > Mount Type
3. Select a combination of of experimental settings, as the following:

"experimental": {
    "virtualMachine": {
      "type": "qemu",
      "useRosetta": false,
      "socketVMNet": false,
      "mount": {
        "type": "9p",
        "9p": {
          "securityModel": "mapped-xattr",
          "protocolVersion": "9p2000",
          "msizeInKib": 4,
          "cacheMode": "loose"
        }

5. Hit Apply
6. Wait for Kubernetes to start

Result

Rancher Desktop fails to start Kubernetes because it looks for the cache directory that does not exist.

I can confirm the issue. I don't get an error dialog; Rancher Desktop seems to quit, but I see the error in background.log.

The problem is not that the cache directory doesn't exist, but that the mount isn't working.

I've not tested further, but I suspect that some combinations of 9p mount options don't work/make sense, and we should reject them in validation. Needs a comprehensive set of tests to figure this out.
