VirtualBox VM concepts
VirtualBox has host and guest OS support
Each VM runs a guest OS
VMs can be cloned to create new VMs or as backups to save state etc
VirtualBox is installed on a host OS
You install a guest OS in VirtualBox VM when needed
After installing a guest OS, install VirtualBox guest additions for that VM
This can provide additional features - networking redirects to the guest OS, common shared folders as drives between the guest and host OS and more
When to use a VM vs a container?
if you want to manage machines, you should use Vagrant. And if you want to build and run applications environments, you should use Docker. Vagrant is a tool for managing virtual machines. Docker is a tool for building and deploying applications by packaging them into lightweight containers
Do I need Vagrant to Manage VirtualBox VMs?
Maybe not. VirtualBox provides it's own UI as an admin console to manage VM instances created with VirtualBox
VirtualBox Network Route for External TCP access from a remote client
The Linux Network settings define how network connections are configured.
Here, I view the TCP connection to get the IP 4 address so I can remotely access the running CouchDB server in Fabric from a Windows HTTP client
http://localhost:5984/_utils/#database/mychannel_fabcar/CAR1
remotely is
http://10.0.0.207:5984/_utils/#database/mychannel_fabcar/CAR1
