 ### Purpose of Lab 1
 
-In order to save money and resources when learning to install, to manage, and to connect Linux machines to form networks, we will be using **Virtual Machines** for this course. In fact, we will be using two virtual machine programs:
+In order to save money and resources when learning to install, to manage, and to connect Linux machines to form networks, we will be using a combination of a local install and **Virtual Machines** for this course. :
 
-- **Lab 1**: Create a **Debian 12 Host virtual machine** (called **debhost**) in the virtual program called **VirtualBox**. This host will be stored on your Solid State External Drive (SSD).
-- **Lab 2**: Install a **Virtualization program package** on your **Debian 12 Host virtual machine** called **KVM** which will be used to create 3 remaining Virtual Machines (VMs) that you will use to learn about Linux system administration for the remainder of this course.
+- **Lab 1**: Create a **Debian 12 Host** install (called **debhost**) on your Solid State External Drive (SSD) which will be bootable on your lab class computers.
+- **Lab 2**: Install a **Virtualization program package** on your **Debian 12** called **KVM** which will be used to create 3 Virtual Machines (VMs) that you will use to learn about Linux system administration for the remainder of this course.
 
 The virtualization software will allow you to create and administer **4 different virtual machines** (**VMs**) on your computer system.

 It is ESSENTIAL to have a **Solid State Drive (SSD) with a minimum storage capacity of 240 GB** or **240 GB available on your own computer** for you to perform the lab work and provide storage for your Debian 12 host and other VMs that you will create in Lab 2. **Due to space requirements, you are NOT permitted to share this SSD drive with any other course material than our OPS245 course.**
