Current Vagrant versions are based on Ruby (this will change in 3.0), I’m not sure if there’s actually a recent Ruby version for Solaris. Also Vagrant is not supposed to manage VMs in a production environment.
You appear to be running Vagrant outside of the official installers. Note that the installers are what ensure that Vagrant has all required dependencies, and Vagrant assumes that these dependencies exist. By running outside of the installer environment, Vagrant may not function properly. To remove this warning, install Vagrant using one of the official packages from vagrantup.com.
Also I succesfully ran the QuickStart example with the Ubuntu 18.x
I could rephrase my original question as “is vagrantup.com going to provide official packages for vagrant” on either Solaris or OpenIndiana please ?
Certainly for Solaris 11.4 this would be useful. It seems from my test (installing from source) that basically it is possible.
Would it be OK to create an IPS (Image Package System) package of Vagrant for VirtualBox and submit it for inclusion in OpenIndiana ?
I.e. is it allowed to package Vagrant for OpenIndiana ?
According to the LICENSE file the software is distributed under a MIT license which seems to explicitely allow one to do this, even sell the software (see LICENSE file in Vagrant source distribution).
The way I currently use vagrant is by installing it from source (and I use a ruby-2.7.4 also compiled from source).
