"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: [code] dinh@CMWPHV1 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`. [/code] Install xorg-x11-apps xauth xorg-x11-fonts* for all servers.
