1. Virtualization

2. ABCs Special software: hypervisors or virtual machine managers Guest OS (virtual machine) sits on top of host OS (Win 7 in our case) We are going to create simulated computers running XP, Vista, 7 and 8 We are going to use Vmware – since it is installed. Could use Virtual PC (free from Microsoft)

3. Hypervisor Windows uses supervisor to handle very low- level interaction among hardware and software One machine, called the host, enabled to run multiple OS’s simultaneously – well, just one extra due to memory limitations Requires extra layer of sophisticated programming – called a hypervisor

4. Emulation Hypervisor can’t make Intel hardware act like Sony PlayStation 3 Hypervisors simply pass code from the virtual machine to the actual CPU Emulator is software that converts the commands to and from the host machine into an entirely different platform – takes lots of horsepower

5. Basic Steps Start VMware Click New Virtual Machine Provide OS installation disk – almost a standard installation Provide a good name – so you know what it is Follow along with the prompts… You just installed a virtual desktop

6. Why Virtualize? Power Saving – one system where we had several Hardware consolidation – same as above System Recovery – the Virtual Machine is but a file on the host system System duplication – making a copy of a system is copying the file Research/Support – many OS’s on one system

7. Managers Vmware – costs but powerful - $149 for student, 249 for full Virtual PC – Free from Microsoft for Windows guests Parallels – For MAC hosts to run Windows - $80

8. Hypervisors “Bare metal” (no host OS) program/OS/manager ESX from VMware is expensive HyperV from Microsoft is free
