Just delete the snapshot. VirtualBox will merge its files with any changes applied since it was created. This process may take a while and the VM has to be powered off.

It is indeed possible in VirtualBox. Check out Section 9.9.1 from the VirtualBox manual, "Using a raw host hard disk from a guest." You'll want to look at the subsection 9.9.1.2, "Access to individual physical hard disk partitions."

It is shown in RAMMap under Driver Locked. See the 3GB uses which is what you assigned to the VM. VMs use this Memory so that no other tools can use it.

TL;DR: The process was using the memory, stopped using the memory, and Windows just has been too lazy to deal with it yet. Windows doesn't show RAM usage in the Task Manager under Process unless the process requested the RAM and has some control over its usage. If the OS gave the RAM to the process to back mappings, and those mappings are discardable, it ...

Do I understand it right that your virtual machine is running Windows? If so, then there is probably no (legal) way around it, and possibly even no illegal one. Windows software is not FOSS (Free Open Source Software); it is licensed under restrictive and binding agreements for use on a specific machine. Once it is by any means transferred onto different ...

In your virtual machine settings, select Network on the left side. Then choose the appropriate adapter from the tabs on the right. Make sure the adapter is enabled, then choose "Bridged Adapter" from the "Attached to" drop-down. From the "Name" drop-down, choose the host system adapter you want to bind the VM NIC to. You may want to create multiple VM NICs ...

If you have direct access to this machine (perhaps via this browser terminal popup thing (?)), you could try to load your kernel and the initramfs and boot it. This won't bring up your system again (because the boot process doesn't only depend on /boot) but you can get into a shell. If you have full access to GRUB this may work: linux ...

Well, the problem with ESXi is that, while you could run all three on the one platform, you'd only be able to interact with it from another system. ESXi has no capability to display the guest O/S on it's monitor. You might look at the free Hyper-V server, which could then run all three? Or if the Windows machine is Windows 8.1, look at adding the Hyper-V ...

I'm not sure what kind of virtual disk format .DSK is or how it was created but you can try to use VirtualBox'es VBoxManage command (especially the convertfromraw subcommand) to convert your disk image to VDI/VMDK/VHD.

Chech if you did install openssh-server server . sudo apt-get install openssh-server then check you have proper port enabled /etc/ssh/sshd_config if you go in it with different port number from outside or your router has a rule of forwarding it to another port you may also need to uncomment in there if you want to be authorized by password. ...

Go in to network settings in Virutalbox and change the network adapter to either bridged or host only. Make sure the VM's IP address is on the same subnet as the host's.

1) when i try to access the host-only ip address shown above in a browser all i get is a totally blank page, why am i not seeing the apache - It Works? Because the Host-Only network address is an address on your Windows 8.1 host computer. I suspect it's there as part of the VirtualBox install, ready in case you have a virtual machine with host-only ...

I had the exact same problem; Hyper-V uninstalled, BIOS/UEFI virtualization enabled, tried forcing the VM to be enabled. In the end, the solution was quite simple: When you install VirtualBox with all the correct settings, it will state that only 32 bit guests are available as before. However, if you then restart your computer and try to load VirtualBox ...

Well, lets break this down to what you need and what you have:- Your base OS (Win 8) requires 2gb of RAM to function (assuming you're using x64), if you lower it down to this level then it will run, but it will run slow. Ubuntu requires 512mb of RAM to function, so taking 512mb is going to be a minimum. Ubuntu also needs 5gb of disk space to install. The ...

With Virtualbox, you could have multiple virtual machines of Windows, one for each user that you want to isolate. When they login to the host machine, you could auto start the Guest VM with VirtualBox --startvm vm_name --fullscreen which would start it in full screen mode. It wouldn't satisfy the "untouchable host OS" as they could still shutdown the ...

The easiest solution is to install DKMS on the server, which syncs time and does a lot of other useful things. This works on my OSX system, running VirtualBox with an Ubuntu VM Guest. All I needed to do was run this on my VM: sudo apt-get install virtualbox-guest-dkms sudo reboot People may need different packages specific to their linux flavor. Ubuntu ...

Easy way: go to "network settings", "port forwarding" and add a rule to map VM port 22 to, for instance, port 9022 on the host. Then run ssh localhost -p 9022. Better way: install Ubuntu lxc package, then, on VirtualBox, go to the VM Network settings, set Attached to to Bridged Adapter, set Name to lxcbr0, reboot the virtual machine and it would get a new ...

Specify a supported x64 CPU. Who knows what QEMU defaults to.

You misunderstand the instructions that you linked to. The "virtual machine settings->hard disk->utilities->expand" section is for VMWare users. You're not using VMWare, you're using Virtualbox. You have already enlarged the virtual hard drive using the Virtualbox utility. The hard disk file isn't 20GB in size because nothing has been written to the ...

Possible solution: The following registry key seems to cause trouble: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers] "C:\Program Files\Oracle\VirtualBox\VirtualBox.exe"="DISABLEUSERCALLBACKEXCEPTION" See if this entry exists. If so, delete it and try again. You may also need to disable your antivirus. If nothing ...

As the menu states, the "Insert Guest Additions CD Image" inserts a disk image on a virtual CD on your machine. This virtual CD usually starts automatically with autorun, but if not, just go to "Computer" and launch the "VboxWindowsAdditions" exe file on the CD and follow the installation.

Chances are good that you're dealing with a network limitation of VMware Player. Specifically, the ability to edit network settings. This is a feature in Workstation but not in Player (what do you expect for free? ;-) Check out this feature comparison between Player 6 and Workstation 10.

Try resizing the VM, then you can change it back if desired. This will hopefully fix the issue. If not, then you may need to try to fix the issue by removing the virtual machine (hitting delete in the portal) and re-deploying it using the same VHD disk that you used. You will also need to re-attach any data disks you were using as well. This will appear like ...

Install a proxy server on the machine hosting the webapp and connect to that proxy from your other devices. Your devices are able to resolve the hostname on the computer, even though it’s defined in the computer’s local hosts file, because it uses the proxy for DNS resolution.

If you enable Lockdown mode you can do this. But it needs Vcenter to login normally. I have read that DCUI disables administrator privileges when Lockdown mode is enabled. So you can configure the privileges. When you disable lockdown mode using the DCUI, all users with the DCUI Access privilege are granted the Administrator role on the host.

Here is how you can change the resolution of Ubuntu (Linux) running in Hyper-V: Open the Terminal and type: sudo gedit /etc/default/grub Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT, and add video=hyperv_fb:1920x1080 (or your preferred resolution) in between the quotes (The maximum possible resolution is 1920x1080) like this: ...

This is conceptual, not step by step, but it should explain enough to help you figure out what you need to do. The Hyper-V switch that the VM uses needs to be either External or Internal and not Private. Keep in mind that an External switch will look like a LAN connection to the VM, not a wireless connection even if on the real hardware it is associated ...

I had the same problem on Win XP host, Win XP guest. What I found is that it's not enough to enter your new key combo and select OK. You have to enter your new key combo in the text box, then click in another box as if you're going to edit something else. Then the changes will stick. File -> Preferences -> Input -> Virtual Machine

If you have both boxes on different subnets inside your VM set they may never talk. The subnets being different are they both using the same gateway? Are they being NAT'd. Your question needs more information in order to better assist you. A layer 3 switch would allow for this but you would need to either have a VM switch or you would need dedicated NICs ...

By far the easiest is to use a Bridge connection for your VM. This makes it look like just any other pc on your LAN, it will be assigned an IP address within your LAN, and it will be able to talk bi-directionally with any pc on the LAN, router included. In this case you can directly forward the port to your VM. You can also make this a permanent arrangement, ...

What set the IP of the eth0 interface on the guest? It doesn't look right; the IP's should both be in the same subnet. Try (on the guest, as root): ip addr del 192.168.56.103/24 dev eth0 ip addr add 192.168.50.2/24 dev eth0 That will delete the existing IP address, and add one that is in the same subnet.

It's not possible to install Hyper-V in azure VMs, because as you may have been noticed, those VMs are already hosted on Hyper-V. Therefore, may you please describe how you would use the hypervisor in your azure VM and maybe we may si if you really need to do so, maybe you should consider an alternative and I would suggest you VMware or VirtualBox.

Using Windows 7 pro with xpvm, I have a lot of problems. The biggest is FINDING an antivirus that works.

There are at least 2 ways: - simplest way is to use VMware tools for sharing. For this option, you need in install VMware tools - as suggested by message in you screenshot. There is a menu for this in VM window once your start it. an alternative is to create a share in Windows7 side, and connect it as network drive from VM side.

Yes. Virtual machines 'do everything twice', and not necessarily efficiently. So, they will use at least twice as much power to process the same instructions as a 'real machine'. The presence of a virtual machine slows things down and uses more power. Basically, OSes like iOS and WIndows will do everything faster and with less power consumption. This ...

Yes, it can be achieved. VirtualBox offers this functionality: VirtualBox can display virtual machines remotely, meaning that a virtual machine can execute on one computer even though the machine will be displayed on a second computer, and the machine will be controlled from there as well, as if the virtual machine was running on that second computer. ...

It won't cause hardware damage, since no actual hardware has been turned off, but the risk of data corruption (e.g. due to the OS not having finished writing cached data to disk) is the same.

I'm leaving the very useful answer from @user287782 marked as the accepted answer, because it's the root of the problem.
