V Intro
* With the new version of Parallels being released I've been playing around more with Virtual Machines and I thought it was time for me to discuss the advantages and how I use them.
V What is a Virtual Machine
* A way to create a completely isolated operating system installation within your normal operating system.
V Differs from emulation which would emulate the hardware, say letting you run an OS written for Intel processors on a Power PC (Virtual PC)
* In a Virtual machine the host OS simply passes the execution of the guest virtual machine directly to the native hardware.
* Basically uses disk images to create a separate environment for a guest OS
V Some uses
V Running a server
* ISPs use virtual servers, since many server applications don't maximize a computers resources
* Some environments require specific servings, security, and configurations that may conflict with another server or application
V Testing items in other OSes
* More secure since environments is sandboxed.
* Running apps not supported by your native operating system
V Why not just use Boot Camp
* Boot Camp is ideal if you need native access to the full resources of the machine
* Also not all apps will work in virtualized environments, especially some that need access to external hardware.
* Main advantage of Virtualization is you can run concurrently
V Why i use Parallels
V Performance
* For a while a switched back and forth between Parallels and VM Ware
* Parallels 6 just seemed faster and I like the UI
V Ease of use
V Installing "appliances" is super easy in Parallels 7
* Support for OS X Lion, Chrome, Ubuntu, Windows built-in
* Windows, you can buy, install, or migrate
* Also download "appliance" images directly from Parallels
V Other virtualization options:
* VMWare Fusion
* Oracle Virtualbox
V Using the virtual Machines
* Control the number of CPUs and the amount of RAM
V View modes
* Windowed
* Full Screen - good option to place it in it's own Desktop
* Coherence - Desktop is hidden. My favorite mode
* Modality - transparent, always on top. Good for monitoring.
V Sharing
* You can map folders and define volumes that are visible to the virtual machine
* copy and paste between OSes
* Suspending instead of shutting down.
V Playing with Windows 8
* Share first impressions of Windows 8
V Metro vs. traditional desktop
* Metro has active tiles and apps
* Metro seems built for touch, but exists in desktop too
V Traditional Desktop is still there, but seems to play a reduced or supplemental role.
* Use traditional "Desktop" for file browsing and navigation.
* Windows Explorer integrates the ribbon.
V Experience seemed schizophrenic to me.
* Internet Explorer has 2 different experiences depending on where you launch it from
* Desktop seems to have a "Start" bar, but it just returns you to Metro "Start" screen
* I think the idea from Microsoft's point of view is to have one experience across tablets, notebooks, and desktops
* An interesting idea, but I'm not sure it works. Apple took the two tier approach and is now merging some elements, but I think they see that some rings are right for touch and other for a more traditional mouse and keyboard.
* Navigating the "Metro" interface with a mouse works, but there was something "unnatural" about it.
