You can safely remove the folder with that VM rm -r "/home/arthur-dent/VirtualBox VMs/Ubuntu Gnome Testing VM 1"

There is another simple way that we don't need to create a new NAT adapter On the host machine, please add the following iptables rules. This will forward packets through the host and on to the Internet: sudo iptables -A FORWARD -o eth0 -i vboxnet0 -s 192.168.56.0/24 -m conntrack --ctstate NEW -j ACCEPT sudo iptables -A FORWARD -m conntrack --ctstate ...

Try Ctrl+Alt+F2 to open a console and then remove the Xauthority file. If that doesn't fix it, try reinstalling xorg. rm ~/.Xauthority sudo apt-get install --reinstall xorg sudo reboot

You can still get antivirus programs for WXP Routers/firewalls provide absolutely no protections against viruses, only hackers. Virtualbox has nothing to do with security when concerning the Host OS Virtualbox has nothing to do with VPN connections either (Unless manually set by the user) Ubuntu can be installed on GPT or MBR partition schemes, as long as ...

You could also download the guest additions .iso file for your version of VirtualBox mount it inside and install it from there. Go to this link find your version and download VBoxGuestAdditions_x.x.x.iso. Then in the lower right corner of the VirtualBox window you should see a dvd icon, click on that and navigate to the .iso file. After that start up ...

This is caused by a lack of video memory. By default, Virtualbox only allocates 12MB to an Ubuntu VM, and as such, the size of the virtual machine is small: The way to fix this is fairly straightforward. Once you create the VM and install Ubuntu, restart. Once you do that, go ahead and press the Ctrl+D. Make sure to press the right KBD, not the left. ...

All I had to do was post a question here. Some combination of the above worked finally. The last thing I did was: sudo apt-get purge fglrx lightdm && sudo apt-get install lightdm ubuntu-desktop and then dconf reset -f /org/compiz/ setsid unity from Unity missing? Can't see top or side panels

The nmap results were the biggest hint that the problem was not the network configuration with VirtualBox. The issue was with Tomcat. I opened the conf/server.xml file in my Tomcat home directory. Then I changed the line <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" ...

In my opinion, for your usage, you shouldn't have to dig in the madness of docker networking. I would advice you to use port mapping when you run your container. For example, say you have created an apache image in docker through your Dockerfile. When you want to run this container, use the -p option to map ports : sudo docker run -d -p=80:80 -p=443:443 ...

You can not run this file on a Windows system! Never. No chance. As you can see in the output of file, it says ELF 32-bit LSB executable, [...] for GNU/Linux 2.6.24. ELF is the format for compiled binary executables Linux uses, and it even tells you that this program is written for a Linux kernel 2.6.24 (which seems pretty old, as well as the CPU ...

You can't run Linux programs in Windows (unless you use some kind of emulator) nor Windows programs in Linux (again except if you are using Wine or similar software).

I had this problem when I was trying to get my own VM up and running. I had downloaded a VDI file off of OSBoxes, and was attempting to use that to create a VM. When you create your own VM, make sure that, when prompted for the creation of a Virtual Hard Disk, you select to use an existing virtual hard disk file. Then, locate the VDI file in your file ...

Based on @gavenkoa's answer, but for mounting an existing image instead of creating a new one:: $ sudo apt-get install qemu-utils $ sudo modprobe nbd max_part=16 $ sudo qemu-nbd -c /dev/nbd0 ~/path/to/my.vdi $ sudo partprobe /dev/nbd0 $ sudo mount /dev/nbd0p1 /mount-target If you have more than one partition, you can access them by number — nbd0p1 is ...

Solved in my case. When I loaded a virtual Mint 17.1 on a Virtualbox 5.0.0, I stranded in this situation. I tried the procedures shown by MountainX. Next, an another error (No support for locale: en_US.utf8) occured and was solved by this command: locale-gen --purge --no-archive After that, I encoutered a login loop and attempted to solved it with a ...

Apparently your Ubuntu installation experiences a crash early at boot, and before you were able to login. This most likely is related to a bug or an incompatibility somewhere. To further find out what causes your virtual machine to crash you may try read the log files from a TTY which I believe you are able to access (press Host + F1). Most bugs will get ...

For auto-resize to work, you also need to install the Virtualbox Guest Additions.

just unmount the iso you used. The problem is the virtual box boots from the iso file you added not from the virtual harddisk

This happened to meet too, for some reason the CPUs were on 4 of 8. I use a Macbook Pro running OS X 10 and Windows 7 using VBox. When I put the CPUs down to 1 it started working much better. check it out.

Maybe a Dualboot configuration works for you. According to this (https://wiki.ubuntu.com/Touch/DualBootInstallation) guide you need to unlock your bootloader. I am not sure, how this affects your warranty. The statement quoted by @TrevorClarke talks only about removing the original OS (which should be kept when using a dual boot).

You should use Alternate CD and not server iso. Quoted from: https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall Starting with the Hardy Heron (8.04) release the LTSP installer functionality was moved to the Ubuntu alternate CD. But alternate CD is not available for Ubuntu 14.04 but you can still use the one for 12.04. Download it from ...

No, it is not possible to run any app when the VM is in save state. Save state is equivalent of sleep option in OS. This is what the official manual says, VirtualBox "freezes" the virtual machine by completely saving its state to your local disk. When you start the VM again later, you will find that the VM continues exactly where it was left off. All your ...

If I remember my VBox correctly, the "save state" mode (called "suspend" in VMware) is equivalent to a bare-bones computer's Hibernate mode if I remember right. On a bare-bones system installation, WoL (Wake on LAN) and a few special BIOS-level things can still operate in Standby or Hibernate mode. The difference about VMs from a bare-bones system, though, ...

By default virtual machines are stored in your home folder, that is /home/larbi/ in VirtualBox VMs. Inside this folder you will find all your virtual machines.

This quesiton leaves a lot of room for opinion, but I'll lay out what I know. I run exclusively Linux for my host OS on all of my computers.

Ultimately how well An OS will perform in a VM will ...

I had a similar problem - could not run virtualbox VMs, and my installed kernel version seemed OLDER than my installed kernel header files. (but with different precise version numbers than in the question.) (I got in this state after upgrading from Ubuntu 14.04 to 14.10 and then to 15.04) I discovered that in my GRUB menu on boot, under 'Additional options ...

If you're able to boot into Ubuntu on the VM your issue is likely with your vdi setup. If you're new to VirtualBox this can be tricky, not to mention if you're new to Linux.

You can go ahead and do this. It won't (meaning shouldn't!) hurt anything, but to be on the safe side, you might want to make a dedicated directory for Windows sharing: In Terminal: sudo mkdir /home/WIN sudo chown [username]:[username] Then share /home/WIN instead of /home. That would be safer, and if needed, you can put symbolic links in /home/WIN/ ...

You need to install guest additions. Start a virtual machine, go to "Devices" menu and select "Install guest additions". Windows video driver will be installed. You will be able to set custom resolutions by resizing VM window by your mouse.

Turns out it was not related to the uninstall of virtualbox at all- I had tried to (and forgotten about) install a newer version of virtualbox after the uninstall and mistakenly downloaded the 32-bit version. Installing that on my 64-bit system is what killed it- and it turned out to be easier to wipe everything and start over for me but perhaps someone else ...

To have a static IP for your server, you have to understand your network configuration. If you are the one managing the IP network, you have to use one of the free IP. Otherwise, please ask your network admin for a static IP and use that. address (enter the IP you got from admin) netmask (enter the subnet mask) network (you can identify your network from ...

It shows because some hotpluged memory is not aligned to page so it will not be used. It's added in this patch to the kernel. The solution is probably VM dependent.
