Yesterday I downloaded EAP 7 for winodws. when I ran the installer it checks for required component and then locks down. It detects my virtual box, which is 5.1.14 the underneath the fieldset it says:
" Red Hat Container Development Kit requires Oracle VirtualBox 5.0.26 or newer 5.0.x release. Please uninstall detected Oracle VirtualBox and restart Installer to continue."
This may be a known issue but I do not know where to look.
