![]() ![]() The command ends with a no space left error message, that is expected. ![]() Copy sdb to sdc with dd command similar to sudo dd if=/dev/sdb of=/dev/sdc.It did not copy data but it did create the partitioning I wanted. Create the correct partitioning on /dev/sdc.Now there are three disks: /dev/sda1 with the running Ubuntu VM, /dev/sdb2 with the source MSWIN7.vdi and /dev/sdc1 with the new vdi. Create a new fixed 160GB vdi and also add this to the Ubuntu VM.Add source vdi MSWIN7.vdi with MS Windows 7 to a Ubuntu VM as a second disk.Resize the disk using Disk Management in MS Windows to a size equal or better a little smaller than the size of the VDI.As shown below I now have my 160GB drive in my guest OS stored in a 160GB fixed VirtualBox vdi file. In the end I managed to solve this puzzle in a unexpected easy way using the preinstalled command line utility dd see Disk Cloning. How can I decrease virtual size/capacity? I tried various settings in CloneZilla but no success. This should be enough to fit /dev/sdb1 and /dev/sdb2.īTW, I tried CloneZilla but it also does not seem to like to shrink the capacity to a smaller disk. I want to shrink capacity to around 160GB. I added this to a Ubuntu VM to look at it using Gparted and CloneZilla. Progress state: VBOX_E_NOT_SUPPORTED VBoxManage: error: Resize hardĭisk operation for this format is not implemented yet!īelow is the disk layout of my vdi disk. Even if you try variants you will consistently get error messages like: Purportedly with vdi you could decrease virtual size/capacity with commands similar to vboxmanage modifyhd MSWIN7.vdi -resize 160000 vboxmanage clonehd -format VDI MSWIN7.VHDX MSWIN7.vdi Using Disk2vhd I have created a vhdx file. If you run for example a Jenkins build server on a dynamically expanding disk you could see the disk expanding quickly to its maximum size while in the guest OS disk space usage is stable and there is lots of free space. This will expand a dynamic disk to it maximum size.Īside from this special case there are other reasons for wanting disks to be smaller and fixed. ![]() It needs to be fixed because I will install PGP disk encryption on it for compliance reasons. This is easy, I have done this before, but this time I needed the virtual size/capacity of the disk to be a fixed and smaller size. I want turn a physical machine running MS Windows 7 into a VirtualBox virtual machine. ![]()
