No, the GPU inside the VM is emulated, so you can't install your host GPU driver. If you need such programs, that heavily use the GPU, install them on the host and not inside a VM.

The problem is that VirtualBox can’t find the file in that path for the VirtualBox machine. What I do in cases like this is delete the machine but do not delete the files so the machine is removed from the VirtualBox list but the files connected to it are left untouched. Then find the actual virtual machine files, double-click the ubuntu.vbox file to get it ...

The real address is fe80::1:1, or fe80::1:1%enp0s8 with the scope identifier. Prefix length (the /64) is only used when configuring the interface and is not part of the address. It is equivalent to the "subnet mask", and you don't give the subnet mask to ping either, do you?

Something must have gone corrupted. A definite solution to recover from such situations is simply to make a copy of the Ubuntu's virtual hard drive (.vdi file) and than create another virtual machine and set it to use the .vdi copy you've created. Provided it worked, you can just get rid of the files of the VM not working. Find the .vdi Since you've ...

Make sure that Hardware Virtualization is enabled in your BIOS. Usually it is disabled by default. VMware and VirtualBox cannot run virtual machines without enabling it.

5chdn's solution is too cumbersome. Instead of Alt, use Win+Alt in guest and you're done. For example, to use Rubymine's multiple caret mode, original shortcut is Alt+click, which becomes Win+Alt+click. Easy peasy.

I had the exact same problem, and saw it through to resolution, so I'm happy to explain the problem and solution in detail. Without Involving a VPN It is important to understand the configuration that is required in order to meet your requirements without involving a VPN. Also, this information assumes that no software firewall is interfering, neither on ...

I was just wondering whether this will make the host connection also under VPN. No, it will not. But let's take a moment to discuss different network types for VirtualBox and how it effects VM network structure. If you configure your VM to use NAT to access the network then your traffic from your VM will be translated to your host's IP address using ...

There is no one single good answer to this. It depends a lot on how you use a VM and on which programs. E.g. using VMWare (a type 2 hypervisor) and a purely CPU bound program yielded almost full CPU speed. If I used the same hypervisor an a program with a lot of system calls I would get a serious slowdown. And things alos change when you use a type 1 ...

For number-crunching programs (very CPU-bound), there should be almost zero performance hit for the VM. The instructions run directly on the CPU, which is the same for host and VM. Even for serious compilation tasks, the performance difference is hardly noticeable. We run CentOS VMs in VMware on Windows. Since you're running Linux on the host, you might ...
