This is a minimal base box built for Vagrant. Initially created using VirtualBox 4.3.24 (now 6.0.2) on Linux x86_64, guest additions installed, packaged using Vagrant 2.2.3.

NOTE: This Oracle Linux 7.6 base box can be updated to latest 7.x minor releases once it is made available via Oracle's Public YUM Server. You also get package updates and errata for free. For example, once Oracle Linux 7.7 is made available, just run yum update -y and stay sharp. Enjoy!

Vagrant Base Box Information

1. Release: Oracle Linux 7.6 x86_64
2. Kernels: UEK R5 => kernel-uek-4.14.35-1844.1.3.el7uek.x86_64, Red Hat Compatible Kernel => 3.10.0-957.1.3.el7.x86_64
3. VirtualBox Guest Additions 6.0.2 installed
4. Default boot target => multi-user.target, /etc/inittab is NO LONGER used due to the switch to systemd.
5. Public YUM and EPEL configured, system up-to-date (packages and errata) as of 22 January, 2019 (UTC+11). Simply run yum update -y as root to stay updated.
6. Users and passwords
   • root / vagrant
   • vagrant / vagrant Public Key authentication configured for vagrant, password-less sudo
7. File Systems Layout
   • Virtual Hard Disk Capacity 20GB, Dynamically allocated
   • /dev/sda1 => /boot ext4 500M
   • /dev/sda2 => LVM Physical Volume
   • /dev/linux/root => / xfs 15GB
   • /dev/linux/home => /home ext4 3.8GB
   • No swap partition (LV) or swap file is configured
   • reserved blocks percentage: /boot => 0%, /home => 0%
   • btrfs support, btrfs-progs tools installed
   • In case more storage space is needed, create a new hard disk using VBoxManage createhd, attach it using VBoxManage storageattach. Then create a physical volume using the new HDD, add it to existing volume group, either grow existing logical volumes or create new ones, as you wish.
8. Networking
   • Networking mode - NAT
   • Port forwarding configured for NAT => VBoxManage modifyvm "oracle7" --natpf1 "guestssh,tcp,,2222,,22"
   • Hostname => oraclelinux7.vagrantup.com
   • For people who prefer the old NIC naming scheme (ethX instead of more predictable enpXsY), pass net.ifnames=0 as kernel boot parameter to revert to old style.
