lsfd seems to be missing from kubevirtci nodes

[0xFelix]

What happened:

The reporter in the kubevirt/kubevirt testsuite tries to run lsfd as part of collecting information about the test environment on a given node. It looks like recent kubevirtci nodes (1.34) are missing this binary.

This output can be observed in the console:

failed to execute command [sh -c lsfd --summary] on node01, stdout: , stderr: sh: line 1: lsfd: command not found

What you expected to happen:

The kubevirt test suite should be able to collection information successfully.

How to reproduce it (as minimally and precisely as possible):

Run make functest on kubevirt/kubevirt main.

Additional context:
Add any other context about the problem here.

Environment:

• KubeVirt version (use virtctl version): N/A
• Kubernetes version (use kubectl version): N/A
• VM or VMI specifications: N/A
• Cloud provider or hardware configuration: N/A
• OS (e.g. from /etc/os-release): N/A
• Kernel (e.g. uname -a): N/A
• Install tools: N/A
• Others: N/A

The lsfd binary is not included in the kubevirtci node images by default, and there’s no evidence it was ever bundled or later removed in recent versions like 1.34. The kubevirt test suite attempts to run lsfd --summary for diagnostics, but since the image build scripts and Dockerfiles do not install it, the command fails with "command not found" see Dockerfile see reporter code.

If you need lsfd available in your test environment, you can manually install it in the node images or containers using the package manager (for example, dnf install lsfd if the base OS supports it). There are currently no tracked issues or official guidance about this missing binary in kubevirtci.

To reply, just mention @dosu.

Error: No matches found. If searching for a file, try specifying the full path or using a wildcard prefix ("*/") at the beginning.

Might have to fallback to use lsof or remove that from the reporter.

My bad, I was working with kind providers when I wrote this and likely forgot to check lsfd was present on the other providers....

@0xFelix @brianmcarey happy to remove it if it cleans up our failure reporting

[0xFelix]

Can we add lsfd to kubevirtci nodes? It might be helpful not only for kind environments.

As far as I can see lsfd is not packaged for stream 9 and building from source feels like a bit of overkill to me but if you think its worth it I guess we could try it.

[0xFelix]

Sounds reasonable to remove it then. Not worth the hassle I guess.
