Alvaro, Robert: I think I've tracked down the culprit. The non-vagrant virtualboxes were running at the time of the power down/reboot and survived with no problem - digging further in to this is what revealed the issue:
I start all my vagrant machines with a command line emulator called Cmder and rarely pay attention to the VirtualBox Manager GUI. While doing some more debugging today I noticed that my non-vagrants were always present in the VirtualBox Manager GUI but the vagrant machines only sporadically showed up (and always showed as being powered off, even if running). I remembered I had set the Cmder emulator to run as administrator (for an unrelated reason, nothing to do with vagrant or this issue). As soon as I ran the emulator with normal privs and issued `vagrant up` the vagrant machines started surviving reboots with no issue. So I guess virtualbox and/or vagrant don't like communicating with each other if running under different user contexts. I don't think that's a bug (more like an implementation limitation/constraint) so, for me at least, the issue is marked 'solved' :) Charlie On Wednesday, December 6, 2017 at 3:53:05 PM UTC, Robert Lilly wrote: > > Charlie, just for clarification, were the non-Vagrant Virtualbox VMs > running at the time of the power down / reboot as well as the the Vagrant > ones? > > I have experienced this problem before on Windows 7 and 10, as well as OS > X / MacOS.
