If you're running things in a VM, there is one serious problem - the time in the VM doesn't get synchronized with the host

This page lists a bunch of things you should be doing, but it's more about how to keep time accurate, rather than it's not working at all

The easiest way to fix this is to just install open-vm-tools^[1]Which will also give you Shared Folders , and this is straight-forward:

rpm-ostree install open-vm-tools

although it's something we would like to avoid doing, being an immutable OS, and all.

This post suggests that it might be possible to run it in a container, but I wasn't able to get it to work, so update the base OS we shall.

We do it in a similar way to before: create a systemd service that runs once during provisioning, and then disables itself when it's done.

The install script looks like this:

#!/usr/bin/env bash
# Post-install tasks.

# install open-vm-tools
# NOTE: --apply-live seems to work, but we need a reboot anyway :-/
rpm-ostree install --apply-live -y open-vm-tools

# all done - disable the service (so that we don't run again)
systemctl disable post-install.service

We install it into the file system via the Butane config file:

storage:
  files:
    - path: /usr/local/bin/post-install.sh
      mode: 0755
      contents:
        local: files/post-install.sh

and create a systemd service to run it:

systemd:
  units:
  - name: post-install.service
    enabled: true
    contents_local: systemd/post-install.service

where the service is configured like this:

[Unit]
Description = Post-install tasks
Requires = network-online.target
After = network-online.target install-k3s.service
Before = systemd-user-sessions.service
OnFailure = emergency.target
OnFailureJobMode = replace-irreversibly

[Service]
Type = oneshot
RemainAfterExit = yes
ExecStart = /usr/local/bin/post-install.sh
StandardOutput = kmsg+console
StandardError = kmsg+console

[Install]
WantedBy = multi-user.target

The service has been configured to run synchronously during provisioning - it takes a while to run, which is a PITA, but if there are problems, I'd like to know about them at the time.

The server also needs to be rebooted - using --apply-live is accepted by rpm-ostree install, but things don't work until the system is bounced However, once you've done that, Shared Folders become available^[2]You might to need to disable and enable them (in the VM's Settings dialog) after a reboot, but I find that I have to do that for desktop Fedora, as well., and the time is correct, even after suspending and resuming the VM (including inside the containers).
