You need to install VirtualBox Guest Additions. The same thing happens with VMWare Player and other software alike. Without the Guest Additions, you have to use Ctrl to switch your mouse from your host OS to the guest OS. By installing Guest Additions, this allows your mouse to be used normally, copy folders/files from the host OS to the guest OS, etc. ...

As per the VirtualBox manual, you must enable I/O APIC to be able to assign multiple virtual CPUs. You also need to make sure VT-x is enabled for that particular guest under the System→Acceleration tab. It is not enough to just enable VT-x on the host. You also won't be able to edit the CPU count while the VM is running or has a saved state. Make sure ...

I have two VMs installed on Virtual Box. And both of them are Ubuntu. But one of them shows black screen upon booting, the login page is not shown. It was totally fine before. Don’t panic! I’ve had this happen to me sporadically at times when launching an Ubuntu Guest OS on VirtualBox. Never understood why it happens, but it always cleared up for ...

It wouldn't matter at all - virtualbox (and well every other virtualisation software )emulates its own video adaptor (IIRC cirrus logic). While the traditional virtualbox file's split up into different files for settings and storage, you can export it into an ovf file as suggested. If your students can install virtualbox or vmware it should be trivial. If ...

As an alternative to most virtualization technology, Linux (e.g. Ubuntu) can be installed on a thumbdrive. Pretty much every computer will boot off a thumbdrive, and most modern installers will detect graphics cards/network cards at boot time. If you install a 32-bit Ubuntu, it will run on almost all hardware the people are likely to have at home. They are ...

I like mperrin’s Vagrant-centric answer, but as you might see from the comments there, my personal opinion is to “keep it simple” and I would recommend a simple export of a VirtualBox OVA as you have configured and passing that along to your students. That said, you ask this: The question is, given people have different graphics hardware, how does ...

You should have a look to Vagrant. Vagrant supports VirtualBox and allows you to: Create and configure lightweight, reproducible, and portable development environments. It will be much easier to share a single or bunch of text files than a big export of VirtualBox image. Especially if you want to manage updates. Once VirtualBox and Vagrant are ...

Try this: airmon-ng And make note of your interface name, for example wlan0. Then type: airmon-ng check kill Then start monitoring mode: airmon-ng start wlan0 Now run airmon-ng once again and note the new name of interface which will be something like this: wlan0mon Now run airodump-ng with interface name as well: airodump-ng wlan0mon

The solution: We've tried to add a driver from an similar printer, edited many configs but this printer driver seems to be bigger. So our special feature (controlling hardware by sending hex on usb->rs232) that had problems with windows just got moved to an ubuntu 12.04 VirtualBox with guest-additions and share usb-device. The Host is windows with the ...

I am running into the same issue. running windows as VM guest and ubuntu as the host. On my windows machine I can access my VPN using Juniper VPN but from Ubuntu I couldn't so far find a way through.

If you can ping, and resolve DNS, it implies you have connectivity. You don't mention specifically how curl or telnet fail. Any error messages? Off hand, the only thing I can think of is that "ping" and DNS are UDP protocols, while browsing, telnet, and curl are TCP. Perhaps your campus network has odd rules locking down TCP connections, but allowing ...

NAT is an option if you ONLY ever want to use that machine from your Mac. Taken from another question (in regard to VMware, but the concept stands) http://serverfault.com/questions/229860/vmware-networking-mode-nat-or-bridged "NAT Mode : Your host computer (the Mac) will act as a gateway to the network for your virtual machines, nobody on your ...

It turned out to be fairly simple. I just set adapter 2 to NAT. This allowed my guest full connectivity to the network and as a result it could access the guest by IP

What you're asking for is called nested virtualization. Unfortunately, Virtualbox does not support it right now. You can follow the feature-request on the Virtualbox ticket here. The "HardwareVirtEx*" configurations you are looking at refer to the top level Virtualbox installation and if it can use the hardware virtualization features of the CPU. My ...

Well, finally I found the answer myself. AndroVM may be outdated and discontinued but this solution remains same for shared folder of Genymotion (upgraded version of AndroVM) or any shared folder in VirtualBox. First thing is If you intend to write anything to shared folder from inside guest OS or Android Emulator, do not check the "Read-only" check box ...

I can access the Internet through the Iceweasel browser but ifconfig shows my IP address as 10.2.0.15 which is certainly not my IP address. Yes, your IP address for the Kali Linux install in VirtualBox is indeed 10.2.0.15. VirtualBox has a virtual NAT server built-in to it’s software to allow for basic routing. Any basic VirtualBox install will be ...

That tool can download an ISO file for you to do with what you want. It's the alternative option to upgrading the PC it's running on. You can even use the Media Creation Tool to automatically burn Windows 10 to a USB drive.

The "not a bootable disk" on the clones makes it sound as though the boot flag hasn't been set on that. How do I check if the boot flag is set? Good question. diskpart is your friend: Start a regular command prompt and run diskpart from that; or you can run diskpart from the Start menu or diskpart.exe directly. It will ask for admin access. list volume ...

VirtualBox now supports .IMA files and lets you boot from it. Just update it to the latest version and it should let you load the files that you have.

The answer is: it depends whether you are using OpenVPN in the bridged or routed mode: you have a routed OpenVPN if your new virtual interface is tunX, a bridged OpenVPN if, instead, you have a tapX virtual interface. For bridged OpenVPN: select, in the VirtualBox screen, Network-> Bridged Adapter, Name -> tap0. For routed Openvpn: select, in the ...

I have solved the problem and posting my solution here for anyone interested. From my router, I made a port forwarding rule for a different port (8997) to the host machine instead of port (8080) Then, on my virtualbox, I made a port forwarding rule for the port (8997) to port (8080) and that solved my problem

I have the same (or at least very similar problem) with a linux host (debian 8) and a linux guest (debian 7) with 3D enabled. Sometimes the mouse pointer becomes invisible at the guest.

Avast 2015 with its option "Enable hardware-assisted virtualization" was the root cause of the fact that VT-x was disabled in Windows 7 for me ;-P Disable it and restart fixed my trouble.

If they already know who you are (if you pay them they do) then there is really no point, is there? To an outside observer your VPN traffic is unintelligible either way.

Ultimately I never found a way to fix this directly; I installed Virtual Box 5 - which I didn't realize had released until I was looking for a solution to this - and things went back to working.

For @FooF Cygwin changes the home directory for VirtualBox. You can fix this by creating a link in your Cygwin home. The links can be created through Windows command shell.

You will have the same ip address when you have created Clone in the virtual box. If you have created a clone from one that you have already created, check the mac address of both the installation. If both of them are same, refresh the mac address and restart the machine.

What solved my issue was using less than 3 GB of ram in the virtual box session. I was originally attempting to utilize roughly 6 GB. You are trying to allocate >3GB of RAM to the VM. This requires: (a) a 64 bit host system; and (b) true hardware pass-through ie VT-x.

You will need to setup a Persistent route so all network traffic from your machine to VM (192.168.59.130) routes through the concerned NIC(Ethernet adapter VirtualBox Host-Only Network #2) route add -p 192.168.59.103 mask 255.255.255.0 192.168.59.3 if 23

The best way to ensure all traffic is routed through your VPN would be to run a VPN client inside the virtual machine. If you're running an OpenVPN client in the VM, you can set the push "redirect-gateway" option in your configuration to ensure all client traffic is directed through the VPN. If the server connection is lost, all client requests should then ...

Sounds like you are looking for a "bridged" rather than a NAT virtual interface. This way you can bind the virtual interface (meaning the interface for communication between your Mac host and the Windows guest) to only one specific interface of the host. As far as I understand the question, you have a VPN interface set up on the host, right? For details see ...

Disclaimer: I've never used Virtualbox so this might not be possible. Option 1 Bind the network adapter of the Windows Machine to the openvpn interface.

I had the same issue with an i7-4790 CPU and an ASRock Z97 Extreme6 motherboard.

These files are for a VMware virtual machine. While you might be able to get it to run with VirtualBox (with the method LPChip mentioned and some additional configuration), the emulated hardware won’t be exactly the same. This is especially true for storage controllers other than SATA. However, if there’s no .vmx file, the main configuration is missing.

This would work for me and should specify the total amount of the Hard Disk Capacity. Not the space what we need to increase...

I found one fix: DO NOT attempt to boot the machine from the install. (may have to hard shutdown the machine) Boot the machine from the Ubuntu 14.04 live DVD. Change the root directory of the live session to the root directory of the install. Rename the directory back to etc.

So the issue is that your home directory is encrypted, and automatically locks again whenever you log out completely. And if the home directory is encrypted, ~/.ssh/authorized_keys is also encrypted, so sshd cannot determine which keys are allowed. You'll have to specify a different AuthorizedKeysFile in your sshd_config, or disable ecryptfs.

I'm guessing this is a bug in VirtualBox 5.0. I haven't reported it yet I'll get around to it sometime in the next decade or so but for the time being I downgraded to version 4.3.28, and the old Windows boots fine.
