I set export UNITY_LOW_GFX_MODE=1 in my ~/.xprofile and it no longer has any effect in 13.04. Is there a way to disable all the eye candy? I'm running in VirtualBox and the Unity 3D mode with all the visual effects is overwhelming for the VM. Unity works and is usable, it's just very slow to render, so I'd rather have it off (is this 2D mode?).

I'm currently trying to run Chrome OS in VirtualBox 3.0.1. Windows XP Pro is the host system.  The actual behavior is Chrome OS starts up fine, reaches the login screen.  Once so, when trying to log using my Google account, I have the network indicator (at the bottom of Virtual Box window) briefly flashing, showing a connection attempt. Nothing happens then, the display stays on the login screen.  The fact that the network indicator flashes makes me think this may be a proxy configuration issue. Indeed, I'm using a proxy to access the Internet from Windows. I guess such a proxy should be configured for Virtual Box as well, but couldn't find anything on the Internet not implying an actual modification of the guest system (for instance,  kind of solution isn't working for me, as it implies accessing to the guest system, what I can't)...  Does anyone have any clues or ideas on how to configure Virtual Box (and maybe Windows XP) to have this working?  Chrome OS version: 999.999.32409.000656, Developer Build Fri Nov 20 00:07:42 UTC

I tried many ways to make a bigger screen in VirtualBox because I do not like the small size of the guest window? Is there is a way to make it big?

I recently installed Ubuntu Server edition 13.10 (Saucy Salamander). But I have run into a bit of problem. At the end of the installation, it asks about several extra packages whether you want them or not, like OpenSSH server and virtual machine host. Here's what I'm looking at:  Now, my problem is that I can't remember if I have checked the &quot;virtual machine host&quot; checkbox. How do I check if my server has the corresponding packages? What packages come with the virtual machine host?

I have an Ubuntu virtual machine running in VirtualBox 2.2.4, and I created it on an 8gb virtual disk which is too small.  So, I am trying to increase the size of the disk.  So far, I have done this:   Created a new larger virtual disk Added the 2nd disk to the machine Used CloneZilla to clone the first disk onto the 2nd disk Removed the first disk Booted up off the 2nd (larger disk)   But now I'm still stuck with an 8gb partition on my new 100gb virtual disk.  Whats the easiest path from here to having a 100gb partition? :) I gather GPart can resize partitions, but it doesn't seem to support LVM2 partitions, which mine seems to be.  thx   Alex

I'm trying to boot Canonical's Azure 16.04 .vhd file in a VirtualBox VM and it hangs at "non blocking pool is initialized".  It works in Hyper-V, so it may only be a bug in virtual box (5.0.20).

Ubuntu runs very slowly inside of VirtualBox.  How do I run Ubuntu with unity or enabled transparency smoothly with VirtualBox?

I have just installed Ubuntu 14.04 on VirtualBox, including the guest additions.   However, the display is really slow. Looking at the display settings I can see that the video memory is only 12MB but I can't move the slider to increase it. The checkboxes for extended features are greyed-out too. See screenshot.  .  How do I increase the amount of memory?  TIA

Since upgrading to Ubuntu 14.04, When I launch my VirtualBox virtual machine I get:  Failed to open a session for the virtual machine win7pro32bit. Implementation of the USB 2.0 controller not found! Because the USB 2.0 controller state is part of the saved VM state, the VM cannot be  started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack'  or disable USB 2.0 support in the VM settings (VERR_NOT_FOUND).  Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}   The solution to the  does NOT fix the problem:  sudo apt-get purge virtualbox sudo apt-get autoremove sudo apt-get update sudo apt-get install virtualbox   UPDATE: Also happens when upgrading VirtualBox itself to 5.0, within existing Ubuntu 14.04.

In continuation to  I used the following commands in order to increase the space available in my virtual machine (Ubuntu):  VBoxManage.exe clonehd "c:\users\a_b\VirtualBox VMs\MyBox_default_1510839571239_2193\Box1.vmdk" "C:\Users\a_b\VirtualBox VMs\MyBox_default_1510839571239_2193\clone.vdi" --format vdi  VBoxManage.exe modifyhd "c:\users\a_b\VirtualBox VMs\MyBox_default_1510839571239_2193\clone.vdi" --resize 102400  VBoxManage.exe clonehd "c:\users\a_b\VirtualBox VMs\MyBox_default_1510839571239_2193\clone.vdi" "C:\Users\a_b\VirtualBox VMs\MyBox_default_1510839571239_2193\Box2.vmdk" --format vmdk   No errors were outputted in the process. However, neither the size of clone.vdi nor Box2.vmdk files was increased to 100GB (that should probably have been my first clue that something was amiss).  I replaced Box1.vmdk with Box2.vmdk as the storage accessed by the VM using the VirtualBox GUI.  When I activated and entered the VM via Vagrant, I checked it size using   df    and saw that the space available to the VM was not increased.  Indeed the sizes available to the two VMs (before and after "resizing") was similar:  Box1:  /dev/mapper/vagrant--vg-root  39625324  13644568  23944840  37% /   Box2:  /dev/mapper/vagrant--vg-root  39625324  13644564  23944844  37% /   How should I proceed to actually resize the VM? If the space is unavailable because the partition needs to be resized, how should I resize it?  Using   sudo resize2fs /dev/mapper/vagrant--vg-root   as suggested in   Yields only   resize2fs 1.42.13 (17-May-2015) The filesystem is already 498688 (1k) blocks long.  Nothing to do!   And   sudo resize2fs /dev/sda1   Yields       resize2fs 1.42.13 (17-May-2015) The filesystem is already 498688 (1k) blocks long.  Nothing to do!   With no changes to size (as evident from the use of df)

I have a Virtualbox VM, with a .vdi that is taking 49gb in the host machine.  I may have used that much space inside the VM once, but now I'm only really using about 6gb.  I tried this command for virtualbox:  vboxmanage modifyhd /path/to/disk.vdi --compact   It started working 0%..10%.....100%. But nothing really happened, the .vdi was still 49gb.  Then I run 'df -h' in the VM and found this:  root@mypc# df -h Filesystem                  Size  Used Avail Use% Mounted on /dev/mapper/mypc-root       2.0T   38G  1.9T   2% / udev                        1.3G  4.0K  1.3G   1% /dev tmpfs                       502M  784K  501M   1% /run none                        5.0M     0  5.0M   0% /run/lock none                        1.3G  160K  1.3G   1% /run/shm /dev/sda1                   228M   31M  185M  15% /boot /home/someuser/.Private     2.0T   38G  1.9T   2% /home/someuser   I don't know why it is using 38gb there.  I cleaned the Trash but it didn't help.  Any ideas on what else I can do?  The VM has Ubuntu 12, with encrypted LVM and home (that's the .Private dir). The host has Windows 7.  UPDATE  I was able to free space for /dev/sda1, but not for /dev/mapper/mypc-root. Zerofree starts and never ends, though I can tell the disk has stopped writting because it stops doing noise after a minute.

I have Ubuntu 14.04 desktop machine that VirtualBox installed on it. I make two virtual machines, one Ubuntu server, the other is Lubuntu client. The default setting allow me to get Internet from guests to Internet through 3G modem connected to the host machine cause the guests use NAT by default, but I can't reach from client to server.  I want to put the two guests in separated network and let the guest server to connect to Internet through NAT with another network interface, and make the guest client connect to Internet through the guest Server.  I did the following:   On guest server I added two network interfaces, one for local network and the other for NAT. On guest client I added local network interface only.   What should I do to make the guest server reach the Internet and then make the guest client reach also to Internet but through the guest server?

I've installed VirtualBox using the Software Centre and I'm running a system on Ubuntu 14.04 with 8gb RAM, 64-bit dual core processor.  I want to run Windows 10, I've tried both 64 and 32 bit versions, in virtualbox. However, every time I start up windows 10 it gets to the point where the dots go round in a circle, then it freezes up and crashes back to the virtualbox manager. The only information it gives me is that the virtual machine was aborted.  I've changed the settings around a lot and nothing is working.  Any help would be appreciated.  Oh, and I've run Windows 10 technical preview on this machine before, a while ago  Thanks for any help in advance.

I would like to know if anyone can help me with installing Ubuntu on VirtualBox

I am running Ubuntu 14.04 from Windows, using virtualbox 5.0. I tried several options to make size of Ubuntu in virtual box larger, but none helped so far.   I am using latest virtual box with latest guest add on installed. sudo apt-get install virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11 I went to Ubuntu 'software and Updates' and made sure that under 'Additional Drivers' tab, 'using x86 visualization solution...' is active. In virtualbox window, under view->virtual screen 1, all 'resize to' options are disabled.   None of these options helped. This is frustrating. Any comments or help? Can the problem be I am using 64 bit system? Does this problem occurs in earlier/later versions? If not, please suggest a 'good' version of Ubuntu for virtualbox.

I downloaded VirtualBox OSE from the Ubuntu Software Center but it seems that that version is limited. I prefer to have the complete version and don't really care if it's closed source or not.  Can I install it via a terminal or do I have to download something from a website?  I don't know how to install software I download from the web. So far I've only used the Software Center.

I have 5 computer systems in our small office. From my basic understanding of Virtualization technology, I think I can virtualize the 5 systems into one big virtual system. I wish to confirm this.  So, for example, if I have 3 GB of RAM and 2 cores on each system, my question is:-   Can I make one big virtual system which will have 15 GB of RAM (3 * 5 sysems) and 10 cores? If the answer to the above question is yes, which is the best free and Opensource software/hypervisor to do this? Can Oracle VirtualBox be a good candidate?   I am a beginner in Virtualization technology so please pardon if the questions are too simplistic/nonsense.
