In the Virtualbox window. There is no OS installed yet. You can install many OS on the VM, but only one

OS can run at once. To toggle between the Virtualbox and the host environment, press the "command"

key on the MAC.

On the top panel click "New". A new smaller window pop-up within. Enter a "Name" for this VM OS you

are about to create, e.g. "Centos_1".

Choose a "Type" for the OS. Centos' type is "Linux". For "Version", choose "Red Hat (64-bit)".

Adjust "Memory size" to 8GB.

For "Hard Disk", choose

"Create a virtual hard disk now", if you never had one. This is the case for most of you.

"Use an existing virtual hard disk file", if you are using one from other person or previous created one.

Click "Create".

Another window pop-up. For "file location", leave it alone, or click the right icon next to it for

determining your own location.

For "Hard Disk File Type", choose,/nClick "Create".

Another window pop-up. It asks where the bootable file is. Right click on the icon next to it, choose the

Centos-xxx.iso file (a CD/DVD disk image) or any virtual OS image that you downloaded. This will create

the virtual OS on the VM. For Centos, you will need to go through configuration to choose files and

features you need. Then on the second configuration window, be sure to create a root password and a

user account other than the root. Give it the administrate privileges, that will make it easier to do things

later on. But be aware that this user can also damage the system, if she/he doesn't know what to do.

The good thing is that you can always create another VM and VM OS.

The alternative to Centos VM is to use VMware or Oracle VM. Windows 10 seems to have difficulty in

installing Centos VM, or VMWare, but it should have no problem installing Oracle VM.

However, Oracle VM doesn't support HOA6 Docker installation well. You will have to redo HOA3 to use

CentOS in order to install Docker./nWhen you configure Linux system, be sure to

Select Ethernet on. If you don't, your VM will not be able to communicate with outside work. You will

have to redo it.

For "Software Package" selection, be sure to choose GNOME Developer", and "Development tools",

otherwise, you will have a hard time to install Docker in HOA6. You won't have the installation

commands and download them will cause a serious installation additional software and potentially

incompatibility.

The Windows 10 method:
