For me, it worked this way
I uninstalled it using
sudo apt-get purge virtualbox
And then I downloaded latest version of virtual box from https://www.virtualbox.org/wiki/Linux_Downloads and installed it.
None of my vm's were lost.
I had a similar issue and I'm guessing it is the same root cause for you since we are both on 18.04 Bionic; however I'm using mainline kernel 5.4.21, I don't believe you mentioned what kernel you're using.
My root cause was that 18.04 Bionic defaults gcc to gcc-7 and the latest VBox 6.1 when run with kernels 5.4.x and 5.5.x requires gcc-8 or higher.
So when ...
Had recently the same problem on Ubuntu 18.04. Apparently, virtual box 6.+ has some issues with gcc-7. These steps did the job for me:
sudo apt-get purge virtualbox-*
sudo apt-get install gcc-8 g++-8
setting default gcc to gcc-8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 800 --slave /usr/bin/...
I have found a solution that worked for me. I am on Elementary OS but i do believe is the same process. I installed the GNOME Disks where it could see all the available resized size but in another partition. Then on the first partition click the settings and then click resize:
and expand to the size you want
I realize this is an older thread, but thought I'd comment as I just had this exact same issue. I deleted the vm and started over, this time allocating more RAM. I doubled the recommended amount and it worked like a charm.
I put this question in the issues from the Github repository of the project, they are trying to work in a enhancement to be able to create snapshot or backups from the virtual machines created. There is a open issue who talks about this theme here if you want to know which is the status of the improvement of the application.
It happens if you don't pay attention to the primary boot disk. When you choose ISO image, also expose the cd as primary. Also, there is the priority for boot in "System option". You can manage them by clicking a small arrow next to Boot order checkboxes.
Otherwise it won't see your ISO image while booting and you'll get this error:
FATAL: No bootable ...
Install Vagrant plugin vagrant-disksize

You should be able to create a VM from your machine using from VMware the 'vCenter Converter'. This will create a virtual machine from your physical machine.
This product should be free. To download you have to register.
If you want to create a Virtual Box machine, you can use this VM to create a new Virtual ...
I know im late to the party but non of the answers worked for me. What you have to do is go on the bios settings or the grub (dual boot manager) system configuration and disable secure boot. It will ask you to confirm and once you go to your system the vm will work. Hope it works for anyone with this problem who cant even use modprobe vboxdrv commands like ...
I had the same issue with a bluetooth usb dongle, but it was an issue with my rights.
Solved from this solution : No USB devices available in VirtualBox
In short :
sudo adduser $USER vboxusers
The above warning message means that you need to enable virtualization technology or VT is enabled from your BIOS, this is different depending on your computer, the usual procedure is:
Reboot your computer.
Look for instructions (on the bottom of the screen) on how to enter bios settings.
In the settings look for VT or hardware virtualization, enable it, ...
Here's how I did it on Ubuntu 18.04 Server guest
Put Ubuntu 18.04 Desktop Live CD in VM's optical drive (make sure boot sequence loads this first)
Boot VM, when CD asks: click Try Ubuntu
Once GUI is up, run terminal
sudo apt install zerofree and let it install
sudo fdisk -l and note system HD e.g. /dev/sda2
sudo zerofree -v /dev/sda2 and let it finish
Everyone's answers are great, I just wanted to more specifically answer your question:
What does attaching the Ubuntu ISO file to an IDE Controller mean?
IDE stands for Integrated Drive Electronics created in 1986 but now most computers use SATA to connect to hard drives. Now in VirtualBox you'll see a Controller: SATA there as well! At first, I thought ...
Identify appropriate interface name: ip a will list everything
Open the yaml file in /etc/netplan. Note: open default file there. No need to create a new file as mentioned in the article linked into the question post.
In the file, write the configuration details (as mentioned in that same article mentioned above)
For e.g. my interface name ...
I re-flashed my Acer Chromebook with SeaBIOS and installed the latest Ubuntu on it (18.04). It works fine, though it doesn't have 'sleep' mode. I'm not sure if that is due to the hardware or the 'SeaBIOS'.
Maybe that's an option rather than using Virtualbox.
When facing the problem,
printed the output:
WARNING: The character device /dev/vboxdrv does not exist.
Please install the virtualbox-dkms package and the appropriate
headers, most likely linux-headers-generic.
You will not be able to start VMs until this problem is fixed.
I tried to open VirtualBox through GUI and it suggested to ...
As per 2020, the only (and clean) working solution for me is the one described in the Arch Wiki as posted by ultracrepidarian.
In the meanwhile the entry in the fstab looks slightly different:
desktop /media/desktop vboxsf uid=<user-id>,gid=<group-id>,rw,dmode=700,fmode=600 0 0
If you create a virtual machine in VirtualBox, you specify the maximum amount of RAM it can utilize. The RAM provided to the virtual machine is only occupied when the virtual machine is running. As soon as you stop it, the RAM is released.
If you find the RAM dedicated to a virtual machine is not optimal (either too low for the virtual machine or too little ...
I had this issue when cloning a VM. The clone had the same MAC address as the original. Because I was running the clone at the same time as the original, there was a MAC address conflict at layer 2. I resolved the issue by going into the VM settings, network, advanced (virtual box) and changing the last character of the VM mac address to make it unique. For ...
I corrected the problem by first Uninstalling vbox 6.1 on my Ubuntu 18.04 system. Then I reinstalled vbox 6.1 to newest revision. After that i updated Ubuntu. Then I uninstalled Win 10 using the fresh install option in windows. I deleted all my files and directories of win10 during the process. This will also delete windows office as well so make sure you ...
