For rke2 installs to vmware, note that open-vm-tools must be installed to prevent cni issues

[mitchty]

Note that when rke2, though not exclusively k3s should be affected similarly like any other userland application in linux, is installed into a system on vsphere. To prevent intermittent errors relating to CNI traffic as well as local inter process IPC, open-vm-tools must be installed to have a CNI setup that doesn't have intermittent tcp errors.

Not sure where we would want to document this guidance appreciated.

PRs are welcome, a good place would be in the requirements page, like as an addendum to the Linux/Windows section
https://github.com/rancher/rke2-docs/blob/main/docs/install/requirements.md#operating-systems

Yes vsphere is not an OS, but it fit with "foundational software/hypervisor" idea for requirements.
