Default Virtual Box from Linux

I have dabbled with virtual software but never got very far. One problem I had was caused by using the same hard drive for my VDI file and operating system. I finally cleared out enough room on my backup drive (which is the slave drive) to to create a 10gb virtual drive. I then installed Mint all went fine.The problem I am running into is that I can't change my graphic options from within the guest system. I end up with about a 8x8 screen. I managed to install the guest additions and still was unable to find a way to change my graphic options. One last thing when I installed Mint at the end of the install process I received a message telling me to change my graphics from 16 bit to 32 bit.

Thanks in advance for any suggestions

OK I've solved the problem. If you are installing vBulletin on Ubuntu 10.10 you need to to download the latest version of vBulletin from their website. http://www.virtualbox.org/wiki/Downloads you will also need to download and install the latest version of the guest additions.
I'm now updating Mint. Downloading gobs of files. Played around with Mint before updating. So far so good.

I guess the minds that be are deciding if they are going to create a Virtualzation section so I will post my question here. I running vBulletin from one drive and accessing the .vdi file from a separate drive. I am experiencing some lag inside the virtual OS its still usable but slightly annoying. Is this normal? I have 2 gigs of ram and a single core AMD Sempron processor.

Cheers

I often document what I do when tweaking things so I remember what to do the next time around if something works well. So I am copying and pasting what I have done. Some of this most certainly depends on your setup, such as if your cpu supports hardware virtualization.

1. Increase memory to vm. remember the memory is shared between host and guest. Give the host the minimum it needs to function, and the VM the greater part.
2. Set the maximum number of cores/processors the Guest OS Supports. Unlike memory this does not depend on the number of host machine cores. Even if you only have one core, your guest OS may support 4, this cores are virtual anyway, so set this setting to maximum. (Note that this tip does not always seem to be true, as there are mixed opinions about it. I think it helped my machines performance, but yours may be different. For the apposing view see link 2 at the very bottom.)
3. Usage of a Dynamic Disk can greatly slow VM/Host performance when transferring files.
4. Defragment virtualdisk file.
5. Install VMware tools / Virtualbox Virtual Guest Additions.
6. Access via Remote Display/Desktop . (Using a Virtual Machine full screen can really cut into its performance. If you simply want to run programs on the VM (like running windows programs in linux) remote into the VM and you will find your performance to be much greater.
7. Keep Virtual Disk files in non-busy and high speed physical disks.
8. If you have them you can Spread VMs across two physical disks.
9 Disable Debugging Mode & Replay Mode (see here) This can bog down your system dramatically. By Default.. VMware has debugging mode turned on with no option to turn it off.

P.S. If you have Snapshots saved on your VMware DO NOT run VMware's Defrag Utility! http://forums.mydigitallife.info/thr...tility-Warning

Thank you Ritho
Much appreciate the tips. Gives me options I didn't know existed. I'm beginning to see virtual environments play by their own set of rules.

Trying to see how vBulletin handles media but now I can't figure out why I'm unable to share folders. I have set one to automatically mount from withing vBulletin but can't seem to access the folder from outside vBulletin or the host's shared folders from inside vBulletin.
LOL....why does it feel like learning how to ride a bicycle again.

I have never tried sharing a Guest folder if that is what you are saying. I don't know if it is even supported. However, it seems very straight forward to share a host folder with the guest. Actually I share a whole partition which I simple labeled "shared."

Please explain your problem in more detail. e.g. Are you having trouble accessing a host linux shared folder from within a vBulletin windows guest, or a host shared folder from a linux guest or what?

To share folders you of course need Guest Additions installed.

On a Win guest the host shared folders appear under "My Network Places> Entire Network> VirtualBox Shared Folders" (It is easiest to use the little plus icons to expand each section rather than opening the folders directly)

On a Linux guest the host shared folders must be mounted in the OS. First create a mountpoint, then actually mount the shared folder.

In Linux Guest Terminal
Code:
sudo mkdir /media/my-shared-folder  (you can call this folder any thing you want)
sudo mount -t vboxsf vBulletin-shared-folder-name /media/my-shared-folder  (The vBulletin-shared-folder-name is the name you assigned it from vBulletin)
Note you can use a script in /etc/init.d/rc.local to make making mounting automatic.

Thanks again for the help
I'm having trouble accessing my host's (ubuntu) shared file from within my guest's (mint) system.
Just so I'm clear as to what's a Host and whats a Guest. I assume the host is the is the computers OS in my case it is Ubuntu. Using vBulletin I created a virtual environment to run Mint which is the guest.
From within Mint I chose to share the documents folder and to auto mount it, on my guest (Ubuntu) I then chose a folder from nautilus made the folder a shared folder.
(enough to make my head spin)

BINGO
Its the same with Linux. My shared folder was in the Mints "My Network Places" I had to use my password to access it. One would think vBulletin would make the process a bit more clear to us knucle heads
Again thank you for your patience is this matter.

PS: vBulletin is outstanding for trying out different versions of Linux. LOL.... I think I'm now going to install Ubuntu 11.04 in place of mint.

When I wrote that last post I was in a hurry and after re-reading it I see I did a poor job in expressing my point.

Quote:
on my guest (Ubuntu)
Should Read: on my host (ubuntu)

Regardless the problem is solved and despite some difficulties its a great way to test drive operating systems. I'm sure with a top end computer vBulletin would run even smoother.

Default error with unity on Ubuntu 11.04 running inside VB

I'm writing this using from Ubuntu 11.04 running from vBulletin

I've run into a slight problem and cant find a solution Everything went very smoothly and I was able to Installed guest additions with no problem. For some reason I can't get unity to load. Thing is I don't no very much about unity so I'm kinda at a loss on how to fix it. During install I received an error message telling me due to a problem with my graphics It could not start unity and was reverting back to its default windows.

After everything was done loading I installed the guest additions and restarted. I still don't see anything that looks like unity. To be honest I can't tell if unity is even running. Doesn't unity have icons on the side of the desktop? Or do I need to configure it somehow?
Feeling like a noob

Wdhpr

Update; I found the problem SOLVED
Ubuntu: it runs Unity. It requires 3D driver support.
Ubuntu Classic: it runs GNOME with gnome-panel. It supports all video hardware and video drivers.
Ubuntu Classic (No Effects): it runs GNOME with gnome-panel. It is in 2D mode only.

Just FYI, there is a 2D version of Unity available. Read more here and here.
