=INVESTIGATION 1: CREATE AND INSTALL FIRST VIRTUAL HOST MACHINE (centos1c7host)=

In this labFor the next 3 investigations, you will learn how to install your Centos Full DVD as a virtual machine using the VMware applicationonto your removable hard disk.Make certain to record You will customize your observations of this install in the comparison chart for to setup several separate partitions:<ul><li>'''/''' (The "root" partition)</li><li>'''/home''' (Store regular user accounts)</li><li>'''centos1/var/lib/libvirt/images''' (store virtual machine images to be created in your lab2)</li><li>'''lab2 logbookswap'''. partition (Virtual Memory)</li></ul>

===Part 1: Using VMware Workstation 12 Make certain to Create a New Virtual Machine (VM) ===record your observations of this install in the comparison chart for '''c7host''' in your lab2 logbook.
