After installing Ubuntu 18.04 on Virtual Box 6.1 the screen is small and we are unable to install Guest Additions.
If you try to access the mounted guest additions ISO image directly, you get mount errors.
Changing the Screen resolution of the Ubuntu worked for me.
Go to Displays Setting and change Resolution.
On the internet people are giving different solutions that could end up corrupting the installed guest OS. After trying multiple times to have the screen size resolved with Ubuntu 18.04, Virtual Box 6.1 running on Windows 10, here are exact steps that will help:
Make sure to install VirtualBox Extension pack from -
https://www.virtualbox.org/wiki/Downloads
Opt to do "normal installation" with following selected - "Download updates while installing Ubuntu" and "Install third-party software for graphics and Wi-fi hardware and additional media formats"
After installation, system will restart but the screen will be small
IMPORTANT STEP: If you click on 9 dots (Show Applications), you should see icon for "Software Update" (spinning circle with A on it). Click on it and ensure all the pending updates are installed
Once all the software updates are completed, open terminal and run following command - sudo apt install gcc make perl
Then click on Devices > Insert Guest Additions CD image
While guest addition is being installed keep focused eye on the output. If any dependencies is missing, you will see it on the screen. If all dependencies are resolved the auto-run should install the guest additions for you and clearly state that install additions will not activate until restart.
Restart the OS and you should see full screen on load.
With latest VirtualBox version 6.1.4, the above did not work as the issue was in Guest Additions 6.1.4. Installing Guest Additions 6.1.5 from https://www.virtualbox.org/wiki/Testbuilds solved the problem. For details refer -https://www.virtualbox.org/ticket/19336
Also I had to assign more display memory. After logging in I have to press Ctrl + F or view > full screen to let the screen scale.
Hope this helps!

I have searched and found the VirtualBox Guest Addons fix, but that isn't working for me. Every time I resize the window in the VirtualBox settings and/or the Display Settings in Parrot Security, it initially resizes to what I want but reverts back to the 800x600 square default (both the VB machine (if in scaled mode) and the Parrot Sec display, although the display settings still say that they are in the higher resolution - see the screenshot below which shows a VirtualBox screen expanded to fit my display, with a Parrot Sec display resized to 1280x800 but only showing as 800x600.
If I click where my mouse is in the screenshot, the window briefly goes to 1280x800 only to drop back to 800x600 a fraction of a second later.
After installing VirtualBox Guest Additions, in your guest machine, open a terminal and run:
sudo apt-get update
sudo apt-get install virtualbox-guest-x11
If it asks you about keeping a file or installing the new one, press I to select the new one/package maintainer's version;
sudo VBoxClient --clipboard
Installing virtualbox-guest-x11 package also resolves the issue where the shared folders are not visible.
And installing this package (and rebooting the virtual machine) also resolves the guest window not auto-resizing when the VM window is resized.
This also resolves the issue where paste after a reboot no longer works and the sudo VBoxClient --clipboard command needs to be repeated. After installing VirtualBox-guest-x11, the --clipboard command does not need to be repeated after each reboot.
I've spent all week trying to find an answer to this issue through google
I have installed VirutalBox 6.0.0 on a Windows 10 64-bit host, and I have created a VM and installed the latest CentOS 7 iso (CentOS-7-x86_64-DVD-1810). I have installed VirutalBox Guest Additions in the guest; there were no errors during the installation, and I'm enjoying some of the VirtualBox features that require Guest Additions (e.g. shared clipboard, shared folders, drag-and-drop, etc).
My only problem is that my resolution is limited to sizes no greater than 1024x768 and the "auto-resize guest display" option in VirutalBox is greyed out. I've tried setting up new VMs. I've tried reinstalling guest additions. I've tried reinstalling guest additions after updating the kernel to the latest version, and without updating the kernel at all. I've verified that I have all of the necessary packages to build against my current version of the kernel (e.g. kernel-headers, kernel-devel, etc). I've verified that systemctl shows the guest additions services as starting successfully. I've tried modifying my grub configuration to use vga=ask and selecting one of the alternative resolutions available there, but CentOS never finishes booting if I do that.
I am at wit's end. Does anyone have any other ideas?
Versions:
Windows 10 64-bit host
VirtualBox 6.0.0
CentOS 7 guest using CentOS-7-x86_64-DVD-1810.iso
After trying an insane number of combinations, I was able to get this working with the following procedure
1) Install clean CentOS7
2) Update to latest kernel
3) Remove all kernel packages for the old kernel version
4) Build VBoxLinuxAdditions
What was weird was that this procedure didn't work for the older kernel (e.g. the one that came with my fresh CentOS7 install, prior to updating it with yum); the CentOS7 installer was installing the headers for the newer kernel even if I hadn't installed the newer kernel yet. So there was some sort of version mismatch between what VirtualBox thought it was building against vs what it was actually building against, resulting in nothing working until I had removed all traces of the old kernel.
I have a Java application that I'd like to distribute as a virtual machine appliance image (ovf or ova) for VMware and VirtualBox using Ubuntu 14.04 LTS. The image would include the operating system itself, required OS packages, my Java application, all pre-configured and ready-to-run when powered on.
What's the best way to create OVF and OVA files?
I have been working with VirtualBox some and do not feel expert, but here is what I would do.
Download the 14.04 LTS iso image from Ubuntu 14.04 LTS.
Build a VM in VirtualBox using the New button. This will be the template for your Appliance.
Give it a catchy name like "Ubuntu 14.04 LTS 64amd for Java App". Type should be "Linux" and Version should be "Ubuntu (64 bit) or (32 bit) as appropriate.
Set the amount of RAM necessary.
Click the Create a virtual hard drive now button. Click the Create button. I believe that VMDK Type will help with portability. Select dynamically allocated (makes a smaller ova file), especially if you intend to distribute the ova files. Give the disk image a name and the size that you desire, I think 10GB would be minimum. Click the Create button.
Next select your VM and Click Settings to get the settings window.
Select Storage and then select the Icon for the CD/DVD disk. On the right, click the CD-ROM icon and locate the Ubuntu 14.04 amd 64 iso file that you downloaded. Click okay.
Then click the start button from the main window .
The VM should boot to the ISO DVD image that is in the virtual CD/DVD drive. Respond to all of the prompts. Save the username and password for later.
When the build is done and Ubuntu boots to the virtual harddrive, then apply all new updates: (you will need your password created earlier)
sudo apt-get update
sudo apt-get upgrade
Then after the reboot, use the "Devices" menu at the top of the VirtualBox window for your VM to "Insert Guest Additions CD Image ..." to install the extras that makes the Ubuntu image work better in the VirtualBox environment.
Now install all of the Java extras and your applications. I can't say much here.
Lastly, using the File > Export Appliances menu option, select your VM from the list and Click Next. I usually accept the format OVF 1.0 and Click Next. Fill in the settings information with links to your support web page if available. I have seen people put the username / password information in the description field for distribution. Then Click Export.
You should have a new OVA VirtualBox Appliance.
I installed Mountain Lion and then I tried to run and then got this error:
The virtual machine cannot enter Unity mode because:
- The guest operating system does not have VMware Tools installed.
- The guest operating system's resolution cannot be changed.
Then I try to update tools:
Could not find component on update server.
Contact VMware Support or your system administrator.
Arkadi's answer is right, here are the detailed actions:
(See also this post for more snapshots)
Download darwin.iso.
Right click your virtual machine in vmware
Click the settings menu item
Select CD/DVD item in the left UI
On the right UI, select and mount the darwin.iso.
Now, the vmware tools installation is started in your Mac OSX virtual machine:
You can download VMWare Tools and graphic driver from here:
VMware_Tools
Graphic Driver - VMsvga2
The links supplied in Boris M answer points to software that is outdated and opens ad-ware sites in browser after install.
Here are the official darwin.iso (9MB) and darwin.iso.sig files from VMware Fusion 6.0.4 for Mac. Put it into vmware/isoimages/ folder next to other ISO files.
Unfortunately, VM > Install VMware Tools menu entry still won't work, so attach the ISO manually and install the package.
I have a problem with VirtualBox - my guest system is ubuntu 10.10 and after update, some of the VirtualBox's Guest additions functions stopped working. For example - before the update whole window of VB was occupied by guest's desktop, and now it's only like 70%. I had the same problem on my other computer with same guest OS, and it's update.
Sometimes you can pick the wrong script file for guest additions. You must use the Linux ones and NOT the .sh Guest Additions hope my tutorial helps you
If you run "apt-get dist-upgrade" then it might update the kernel. This can mess with the guest additions. You will have to re-install guest additions after doing the update. Then everything should be fine.
