Virtualbox development environment setup

Adapter 1 leave as NAT

Add Adapter 2 as Host-only Adapter on vboxnet0 with Promiscuous Mode denied.

First rule is that the Guest Additions Shared Folders are very rudimentary and do not maintain user ownership nor permissions.

For a secure network such as the host-only network between host and guest, use NFS.

Host: Install NFS server software: # sudo apt install nfs-kernel-server
Guest: Install NFS client software: # sudo apt install nfs-common
Determine your host and guest ip numbers and either use them or assign names to them in /etc/hosts
Host: Export shared directory: Edit /etc/exports adding a line like:
```
/sharedhostdirectory guestname (rw,sync,no_subtree_check)
```
After editing the exports file, restart host NFS-server sudo systemctl restart nfs-kernel-server

Guest: Mount shared directory: Edit /etc/fstab adding a line like:

hostname:/sharedhostdirectory guestmountpoint nfs auto,nofail,noatime,nolock,intr,tcp,actimeo=1800 0 0

For example:

vbhost:/srv/www /srv/www nfs auto,nofail,noatime,nolock,intr,tcp,actimeo=1800 0 0
