“Good artists copy, great artists steal” – Pablo Picasso
I am currently using Vagrant boxes from Mikael Sandström (oravirt) and unfortunately, it did not have X11 configured. Typically, using CLI is better for automation; however, there may come a time where it’s better to have visual.
This led to a journey to configure X11 for Vagrant box.
Configuration is two nodes RAC:
[email protected] MINGW64 /d/Vagrant/vagrant-vbox-rac (master) $ vagrant status Current machine states: racnode-dc1-2 running (virtualbox) racnode-dc1-1 running (virtualbox) This environment represents multiple VMs. The VMs are all listed above with their current state. For more information about a specific VM, run `vagrant status NAME`.

In conclusion, having X11 configured will provide options to use CLI for GUI for installing Oracle software.

Many thanks for detailed instructions. Very helpful.
I am having a problem when trying to start xclock.
My host operating system is Windows 10 and I start xvcsrv with ac disabled.
My guest operating system is Oracle Linux 7.8. This is output when trying to start xclock:
[[email protected] ~]$ xclock
debug1: client_input_channel_open: ctype x11 rchan 3 win 65536 max 16384
debug1: client_request_x11: request from 127.0.0.1 42014
Could not find ‘:’ in DISPLAY: needs-to-be-defined
debug1: failure x11
Error: Can’t open display: 127.0.0.1:10.0
Thanks!
Try Xming instead.
After you start Xming, review the log from system tray to find newAddress 172.16.7.1
export DISPLAY=172.16.7.1:0
