Use a thumb drive or a shared directory / partition on the windows side for your code shared with your VM and duplicate that share on the Linux VM. Linux can access (R,W,X) everything in the Windows partition / drive via the ntfs-3g package but Windows cannot see or access anything on the Linux side so that is why you set up the initial share on the windows ...

I am unclear what you have done to compact the disk. Did you create a large file on the disk with 0's and then delete that? If not, doing that will help significantly. It occurs to me that you likely also have swap. I expect that zeroing out the contents of the swap partition will make a substantial difference. I have not tested this, but I expect you ...

Explanation: This is caused by the WLMS (Windows License Monitoring Service). Some suggested to try: slmgr /rearm, which will only temporary fix this issue, but you will need to run this every 30 days or so, and it didn't seem to work on my machine. (Windows 10 x64 Virtualbox) Permanent solution (and the only thing that worked in my case) is to delete WLMS ...

I had the same error Could not find an open hard disk with UUID {ab625445-c564-4ed5-ab89-2a3e75de7d6c}. The solution which worked for me was simply to execute the following command: cd ~/VirtualBox VMs/Win7-VirtualBox/Snapshots VBoxManage showhdinfo \{ab625445-c564-4ed5-ab89-2a3e75de7d6c\}.vdi After that the problem was gone and it works again very well. :-) ...

Had an SOB time converting this. I had backed up all of my hyperv's before moving to linux, only to find out you have to specifically export them from Hyper-v in the vhd format. After getting on linux I realized virtualbox doesn't support vhdx. I had to boot a windows 10 VM, move the files over, install hyper-v and all associated components, just to convert ...

Just because you see these numbers on the guest, doesn't actually mean the mounts are actually consuming space on the guest. VirtualBox shared mounts behave a lot like network filesystems – when you run df on them to check disk usage, you're really seeing disk usage of the host system where the folder was mounted from. If your host system's disk is 98% full, ...

VirtualBox is a general-purpose full virtualizer for x86 hardware. It might not function correctly on other hardware (e.g. cannot run x64 guests). Disable hardware acceleration in VirtualBox to fix some problems. That is often (well, sometimes) a cure for virtualization failures. Both Intel and AMD add dedicated tools for virtualisation into their processors,...

The obvious solution is to run Windows XP, not Windows 7, in the virtual machine. It's perfectly safe to connect your virtual machine to the internet. Your emulated Windows XP is running in a 'sandbox', and, although it's exposed to the internet, if a virus was to run within the virtual machine it could only compromise Windows XP. It couldn't affect Windows ...

The problem is the nested virtualization not being supported (meaning: you can't run a VM inside a VM; Windows Virtual PC mode is a VM for all intended purposes, it's even in the name). You may need to run it in a native Windows XP VM, just don't allow it to connect to the internet, but the same goes for the now defunct Windows 7. A better solution is to use ...

Vmware 15.5+ will work even if Hyper-v is enabled With the release of VMware Workstation/Player 15.5.5, we are very excited and proud to announce support for Windows hosts with Hyper-V mode enabled! As you may know, this is a joint project from both Microsoft and VMware.

Just in case someone's still stuck with this: Create a VHD with windows Disk Management (click on a partition where you want to save the vhd image, then goto menu and do 'create vhd', select fixed size and vhd not vhdx) Download free daemon tools 10 lite, then click on mount VHD with options and select 'removable drive' Tested to work with Windows Recovery ...

If you still have your original VM on your laptop, a better way to move it to a new host is to export it as an OVA. In Virtualbox, click File | Export Appliance. That will generate a single .ova file. Then on your new host, click File | Import Appliance and point it to the OVA file.

It appears VirtualBox no longer exposes this setting in the user interface. As mentioned in my comment, the real solution is to enable hardware-assisted virtualization for your PC. It not only offers much improved performance but is also required for 64-bit guests. Barring broken BIOS/UEFI implementations, any modern system should support Intel VT-x or AMD-V ...

As far as I know, you can't pass a PCIe card to VirtualBox from a Windows Host. It is possible from a Linux Host, or Xenserver, and even then you need to have the correct hardware in other to do so. The CPU hypervisor need to be enabled for example. At best with a Windows host you can get more video ram(up to 128mb is I remember right)once you dealt with the ...

In my experience Windows can occasionally hang network devices(/connections) during sleep, or power reduction cycles, if you make no other changes but to reboot the Ubuntu server you may be looking for an issue outside of VirtualBox/Ubuntu directly into the mirky world of drivers, etc. It is possible that changing your power management settings in BIOS, or ...

Just for the completeness: if you come from Google like me, but you are running a Windows VM in Hyper-V. You have to disable the Time synchronization Service in the Settings of the Virtual Machine. Right click the VM → Settings → Integrated Services → Time synchronization

This can sometimes happen on certain OSes in Virtualbox when you save the machine state with capslock set to ON. You should be able to fix it by setting capslock to ON on your keyboard, saving the machine state, switching capslock OFF on your keyboard and then restarting the VM.

I would look for problem in DHCP lease. Does it have enough time? Maybe it does not lease again the IP address? First of all you should look into /var/log/syslog for any errors and network related issues.

No, your DHCP server is working correctly – in DHCP, the Client Identifier option always has priority over the actual MAC address. So as far as the server is concerned, those requests are coming from the same host. The actual problem is that all of your VMs are specifying the same client ID. In your case, the client ID is of type 0xFF ("Opaque"), ...

Setting the --tls-san and --node-external-ip params did the trick. That way the k3s master listens on its real IP and accepts requests by putting its IP inside the cert. Master node setup masterIP="192.168.30.10" k3sTokenFile="/var/lib/rancher/k3s/server/node-token" flags="--tls-san $masterIP --node-external-ip $masterIP" echo &...

You can install a Mesa3D OpenGL DLL alongside the program you want to run and this will give you OpenGL 3 support. But this is a software renderer, so how useful it is will depend a lot on what you're trying to do with it. If it's something that has demanding 3D rendering requirements, it will not be useful. If it's something that has very low rendering ...

All terribly wrong answers. During first boot from live CD, you first need to exit the installation screen. You can select "Try Ubuntu" button. Then just right-click the desktop, select Display Settings, and choose a different resolution. Then run the installer. I did have to re-select the resolution again during the installer for some reason. The ...

I had the same problem and I fixed it by running cmd as administrator. Hope this helps.

The answer that I found to fix it was: 1.- Open the .vbox file with Editor, you could see if your file is empty, contains logs or is not complete. (In my case the file contains logs) 2.- Create a new vm with the same specs that your previous vm. 3.- Copy the new .vbox, and paste in your vm that contains the error. 4.- Edit the .vbox in the vm with errors. ...

The titular question is whether it is possible to convert a VM to a physical drive (V2P). The answer is yes. Several answers to this question take an external approach. That is, treat the VM like a single file (i.e., a VDI), and convert it as such. External approaches seem to have been less successful overall. They certainly were for me. Most V2P efforts use ...

Did you extend the volume in the guest OS? Windows won't use the space until you tell it to do so. Microsoft has a guide on how to do this: https://docs.microsoft.com/en-us/windows-server/storage/disk-management/extend-a-basic-volume Depending on how the disk was partitioned, you may not be able to extend it from Windows. For example, if you're trying to ...
