What you need to do if you have taken a dd or real raw image dump of a hard disk: VBoxManage convertdd windows2019-eval-template.img windows2019.vdi --format VDI The .img is the raw dd dump and the .vdi is the output file. --format VDIspecifies to output to .vdi format If you are in a pinch you can always use qemu-kvm binary and manually specify the .img as your disk and i........

It is a permissions issue that is hard to fix. All but one USB device is greyed out. I am already a member of "vboxusers" I have already enabled and disabled USB support for the guest. I have already reinstalled the latest VBOx guest editions If running as root it all works fine Changing........

I haven't updated VBOX in ages but have never seen this issue and it has my CPU running at 100C. Manually/forcefully killing the process does not work with "kill -kill 3892". I've closed the VBOXManager and everything else related to it. This did seem to happen around the time I ran VBoxManage clonehd and it failed, the terminal issue locked up and also never wrote a byte of anything. I forced killed the VBoxManage and tried to remove &........

I doubt this is safe to do while the VM is running and I'm not sure if it would attempt it still but turn the VM off first to be safe. I also notice in the VBOX GUI that it still shows the orig........

VBoxManage modifyvdi /path/to/your.vdi compact I believe this should be done only when your VM is powered off, but I decided to try it with the system powered on. i wouldn't recommend it because it's dangerous even if it does work but this is a test system. For anything important/production I would always take a backup first and make sure the system is powered off. VBoxManage modifyvdi XP-clone.vdi compact 0%...10%...20%...30%...40%...5........

You can't just do a straight copy of the VDI image of your virtual machine because there is a unique UUID, wellI believe you can and then you can create a new UUID manually (at least you could with VMWARE) but to keep it clean just use this method: VBoxManage clonevdi /path/to/your.vdi outputname.vdi 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% That's all there is to it, just wait for it copy and you can th........

I wanted to Import/Use a .vmdk hard disk image file from VMWare. Generally you can just "point" VirtualBox to it and use it and it will work but I found an exception. One of my Centos 4.4 x64 images wouldn't boot. I had two copies, an older one and the newer one. The older one booted as normal (once I changed the VirtualBox driver to IDE from SATA). The newer one stopped at the "GRUB loading" message no matter what I tried. As far as........

Virtualbox Error I tried to copy a .vdi of one container to use in another one, basically to clone instead of having to install the OS again. Failed to start the virtual machine Centos 5.5 Mirror.
