As you can see above, Containers make use of your Host OS and its kernel, and therefore are "closer to the iron". For example, in order for a Container to read/write from your Host OS hard drive, it has to:
VM's run an additional operating system on top of your Host Operating System, as well as an additional abstraction layer (called the Hypervisor) for the "Guest OS" to talk to the Host OS. For example, in order for a VM to read/write from your Host OS hard drive, it has to:

In the guest Windows system open Windows Explorer, go to the virtual CD drive (disk D: in this case) and run VBoxWindowsAdditions-amd64.exe file to install VirtualBox Guest Additions on the Windows 10 guest.
Since VirtualBox v.6.0.0 was released, VirtualBox Guest Additions have been provided for macOS guest OSs, while earlier versions of VirtualBox did not include Guest Additions for macOS. Unfortunately, the current version of macOS Guest Additions does not contain macOS graphic drivers to change the VM display resolution automatically when stretching or maximizing the guest VM window. Only the basic functionality is available right now, which means that you cannot use the same method of changing screen resolution as for Windows and Linux guest OSs running on VirtualBox after installing Guest Additions.

Never tried it with windows but something like clonezilla could work for windows. I had a old nvme drive laying around so i decided to use it that's the only reason i switched to it. The performance is good but i do not do much but watch videos and movies using the VM. vdisk are still very good with performance and way easier to back. Just decided to give it a try.
Unfortunately, I don't seem to get it working. Issue seems to be that the VM (and Unraid) crashes once I start the cloning process. Issue seems to be that I am accessing the network. I also tried before to copy things from the network to the VM, which also crashed the VM and even Unraid. Seems some network driver issue?
Cloning now. I just realized that I can actually add "unraid shares" to the VM. I've never done this after using VMs for many years. Does this allow me to access drives from the array within the VM directly. This should be much faster than mapping them as network disks? is this how it works?
VMware tools are essentially the drivers that helps enhance the performance of your virtual machine. It's not required by default but it does offer a lot of benefits in terms of optimizing and providing additional functionality.
The installation operation changes the boot device order to boot the virtual hard disk first and then the virtual DVD drive. If the virtual hard disk is empty prior to the automatic installation, the VM boots from the virtual DVD drive and begins the installation.
USB. Oracle VM VirtualBox emulates these types of USB host controllers: xHCI, EHCI, and OHCI. While xHCI handles all USB transfer speeds, some legacy guest OSes may not support xHCI. Note that for some legacy Windows guests, third party drivers must be installed for xHCI support.
Boot Order: Determines the order in which the guest OS will attempt to boot from the various virtual boot devices. Analogous to a real PC's BIOS setting, Oracle VM VirtualBox can tell a guest OS to start from the virtual floppy, the virtual CD/DVD drive, the virtual hard drive (each of these as defined by the other VM settings), the network, or none of these.
In a real computer, so-called storage controllers connect physical disk drives to the rest of the computer. Similarly, Oracle VM VirtualBox presents virtual storage controllers to a virtual machine. Under each controller, the virtual devices, such as hard disks, CD/DVD or floppy drives, attached to the controller are shown.
Oracle VM VirtualBox also provides a floppy controller. You cannot add devices other than floppy drives to this controller. Virtual floppy drives, like virtual CD/DVD drives, can be connected to either a host floppy drive, if you have one, or a disk image, which in this case must be in RAW format.
You can modify these media attachments freely. For example, if you wish to copy some files from another virtual disk that you created, you can connect that disk as a second hard disk, as in the above screenshot. You could also add a second virtual CD/DVD drive, or change where these items are attached. The following options are available:
To add another virtual hard disk, or a CD/DVD or floppy drive, select the storage controller to which it should be added (such as IDE, SATA, SCSI, SAS, floppy controller) and then click the Add Disk button below the tree. You can then either select Optical Drive or Hard Disk. If you clicked on a floppy controller, you can add a floppy drive instead. Alternatively, right-click on the storage controller and select a menu item there.
For virtual CD/DVD drives, the image files will typically be in the standard ISO format instead. Most commonly, you will select this option when installing an OS from an ISO file that you have obtained from the Internet. For example, most Linux distributions are available in this way.
The Default option is enabled by default for all new VMs. This option selects the best audio driver for the host platform automatically. This enables you to move VMs between different platforms without having to change the audio driver.
On Windows hosts, a kernel mode device driver provides USB proxy support. It implements both a USB monitor, which enables Oracle VM VirtualBox to capture devices when they are plugged in, and a USB device driver to claim USB devices for a particular virtual machine. System reboots are not necessary after installing the driver. Also, you do not need to replug devices for Oracle VM VirtualBox to claim them.
For me, the solution was discovering that you have to add an Empty optical drive in the virtual machine settings! If you try to "help" by pre-loading the VBoxGuestAdditions.iso, it doesn't work. The shortcut on the Devices menu "Insert Guest Additions CD image ..." wants to find an empty optical drive to use!
Same error for me with Macos. I was hitting the error Could not mount the media/drive '/Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED). The guest additions iso was already downloaded previously. All steps are done within VM.
The next step is to set the hard drive for new VM, for which you can pick the Create a Virtual Hard Disk Now option, choose VDI for the drive type, select the option for a fixed drive size, and set the drive size to about 20 to 25GB. You can allocate more if you think you'll be using a lot of apps on the macOS installation.
On the macOS Utilities page, click on Disk Utility and hit the Continue button on the bottom right. In Disk Utility, click View and select Show All Devices to see your Big Sur blank image on the left. Now, click on it and give the name Macintosh HD to the drive in the popup window pane; set APFS as your format and GUID Partition Map as the Boot Scheme. If the format is showing you just the Extended version or something else, that's fine. There have been some changes since macOS Catalina. Next, click Erase, which will erase the blank drive and take you back to the macOS Utilities window.
This time, click on Reinstall macOS and the Continue button. Agree to the Terms displayed on your screen and choose Macintosh HD as your hard drive. Click Install. The rest of the installation process will now be executed so this could take a while. However, at the end of the process, you'll be taken back to the installer. Don't worry, this is the expected result. Follow the final two steps below to complete the process. Patience is a virtue, you know!
Open VirtualBox again, select the VM from the left side -click on Settings-> Storage-> select the Disk drive and in right side info, you will see the increased amount of storage.
You can see how to copy the path of the drive which size you want to increase in above steps for windows & Ubuntu, which will be the same for MacOS too. After copying the path, jot down it somewhere and then shut down the VM and quit VirtualBox.
In a VM, everything is virtualized into signals or files in respect to physical hardware and signals on a tangible computer. In a physical machine, a hard drive is a 3.5" or 2.5" rectangular box with platters (or SSD) inside.
Next, we need to decide the size of the hard disk. I am going to allot 15 GB to my virtual drive. Kali Linux requires a minimum of 10 GB of space, so 15 should allow me wiggle room. You will also need to select the location to save your virtual hard disk. This can be done by clicking on the folder icon by the "Name" field. I usually keep mine in the Documents folder, though, it doesn't really matter where you put it. Once you are finished, click the "Create" button.
The future bare-metal hypervisor will support eight processor cores, 64GB of memory, 2TB disk drives with multiple drives per partition, and up to 16 virtual network interfaces per VM. Both 32-bit and 64-bit operating systems will be supported within the VMs, and as was the case with the Mac version of Parallels Server, the bare-metal hypervisor will function without the Intel VT or AMD-V virtualization-assistance electronics inside most current x64 chips - but it will perform better with it, according to Beloussov. 2ff7e9595c
