It is recommended that no other Vagrant processes are running during the upgrade process. It is absolutely the same as th log of successful booting with Ubuntu 14. I don't see any error in the VirtualBox log. The appropriate VirtualBox process is using 100% CPU on the host. it did not give me login prompt on the gui.
#Vagrant upgrade update
The upgrade had no error, but after I restarted the guest system I could not log in through ssh into the guest. If you already have installed the Vagrant boxes you can upgrade them with: vagrant box update
The server is running in a Vagrant/VirtualBox virtual machine. To get started with Vagrant, download the appropriate installer or package for your platform from our Vagrant downloads page. vagrant box add centos/6 for CentOS Linux 6, or. I have a running WEB server with Ubuntu 14.04.5 LTS with LAMP environment.
