Forget dual-booting! Virtualization 101 - Page 9

post #81 of 95
Thread Starter 
Reviewed for update. VirtualBox is now owned by Oracle since that company purchased Sun. May update screenshots later, but it still looks about the same so probably isn't necessary.

Just curious, why do you suggest EIST/C1E be disabled? It doesn't affect VM performance either way from my experience.

In certain combinations of host and guest OSes, having these enabled can cause the guest clock to drift. For the most part, virtualization solutions compensate for this and it isn't usually a big problem, but it can occasionally still happen.

You may want to mention that on Windows all Virtual hard disks are stored in the user profile on the C: drive. I was certainly alarmed when I first realized my C: drive free space was gone (I use a super-small capacity drive for the OS). It's not that obvious that is where it is stored and it's not that intuitive (to these old Windows-oriented eyes) how to change the storage location for these files.

Also it's probably always been possible but it seems easier some how in recent versions to give a VB VM a normal IP address (if your host is 192.168.1.100, the VM can be 192.168.1.101) instead of a NAT-ed one. This is is of note both if you want to host a web server or whatever or you can actually RDP into a Windows VM. Almost makes guest additions unnecessary...

You have your user profiles on a super-small drive? For that matter, the C drive?!? Time to move those. This has nothing to do with VirtualBox.

Sure, you can do it either way. But if you've gotten to that point, I doubt you need a beginner's guide any longer.

Doesn't it? Doesn't it though?

Most, if not all, Windows-native applications will store related data some place standard like my documents. Storing potentially large files in some subfolder under %USERPROFILE% is perhaps standard on unix/linux type OSes because it is the "home" directory but in Windows it is entirely non-standard and every bit annoying. Perhaps "beginners" to VMs (but other-wise "enthusiast" types) would be panicked when they're suddenly getting "low space" notices for their C: drive. Or I could be way off.

Applications do store user-specific information there (like cache or whatever) but not actual data files like multiple 4gig files...I've noticed this is common with programs ported from linux (I use jedit all the time at work).


And it's not "super-small" (120 gig IDE drive) but I like to keep the OS stuff as isolated from the data stuff as possible. I did back ups with Ghost 8 at one point so it was already imperative to keep that OS drive as small as possible so I didn't need that much space for backup (then I can restore just the OS and not worry about my data).

Of course there's some people using 80 gig solid state drives who still have their profile on C: so this would be something to note.

On a side note I'm weird since I don't care how fast the machine boots as long it's FAST when it's done booting (my sig rig fills that bill). Thus I'm not buying a sold state until they're a reasonable capacity for ~$90

Well, keep in mind that you can locate the VirtualBox VHD virtual hard drive files wherever you like.

I also wouldn't keep %USERPROFILE% on a SSD. That directory includes fun things like every user's favorite file dumping ground, the Desktop, in addition to the Downloads folder, My Documents, and so on. Most of which has little benefit to being on a SSD, and many of which can be very large in their own right. It's not unreasonable to think a user's personal files should be located there, since that's where Windows puts them! (And yes, if you're using VirtualBox, the virtual machine is your personal files.)

For my security class we all just set up VM's to run a a group of apps that run on Linux 2.6. I was very suprised and pleased how easy it was to move from the VM back to Windows, I saw only gain and no downside. This was all on an e5200 4gbRAM machine. I am all for VM's it is just now I would like to find time to evaluate hyperV and VMware as the only hypervisor I have used so far is Virtual Box. Some say to setup a VM even if you do not change OSes, it is a great isolation feature (adds to your personal security).

Okay, so I'm finally diving into this. Tried Virtual PC 2007. Worked great except that I can't go 1920X1200 in fullscreen. Tried to install the hotfix update and it just won't install. Tried VirtualBox instead and it works flawlessly...until I found out the drag and drop function doesn't exist. Any suggestions?

"You'll find now that sound and graphics work really well so you can watch videos now on your windows spice enabled guests. " .. i don't quite have it working yet, but we are not far off
