[CentOS-devel] Anyone using the serial console from our Vagrant boxes?

It isn't enabled by default in Hyper-V. It would be easy for me to add though in Vagrant if needed. Let me know.

The problem is that VirtualBox doesn't enable a serial port by default, and our boxes hang if they really need to use the console, e.g. during relabeling[1] or during the initial configuration required for sealed VM templates (what I'm currently trying for Hyper-V support).

Otherwise, a patch for Image Factory is trivial - I can just the set the port to enabled in the XML file, without the cable connected, and probably move console=tty0 on the last position, so it becomes the active console.
