Hyper-V vs VirtualBox: what’s the difference?
Hyper-V and VirtualBox are different types of hypervisors. In general, the hypervisor is a software solution you use so that one or several virtual machines are launched with their own operating systems (guest operating systems) on the host machine.
Hyper-V is a type 1 hypervisor, which runs on computer hardware. Hyper-V hypervisor management comes from the BIOS or UEFI. Hyper-V then automatically launches the management operating system (or you can do it manually), which can be Hyper-V Server, Windows, or Windows Server. Hyper-V is always on when the host is on.
VirtualBox is a type 2 hypervisor, which runs on the operating system and is installed on the host. VirtualBox can be started and closed by the user on demand. The user also launches VirtualBox, and then starts the necessary virtual machines.
VirtualBox vs Hyper-V: OS differences
Hyper-V supports only Windows, starting with Windows 8 and later. Also, the server may be in Windows Server 2008 and later.
Virtualbox in this regard is more versatile. You can use Linux, Windows, Solaris, and Mac OS.
Therefore, if you have Windows installed on physical machines, then Hyper-V will be a great option. Otherwise, VirtualBox will be your solution.
Hyper-V vs VirtualBox: Guest OSs
Dawn OS VM is a virtual machine, and it may differ from the host operating system.
Hyper-V supports virtual machines with guest operating systems such as Windows, Linux, and FreeBSD.
VirtualBox in this regard is also more variable: you can use Windows, Linux, FreeBSD, Solaris, Mac OS, and others.
VirtualBox vs Hyper-V: disk formats
- 1. Hyper-V uses virtual files as VHD and VHDX files.
VHD is an earlier virtual disk format that is now rarely used.
The VHDX format is used with Hyper-V in Windows Server 2012.
There is also a division into two types of virtual disks for pre-allocation:
- Fixed virtual disk. This type of disk takes up all the allocated space in the storage after it is created, similar to a thick provision.
- Dynamic virtual disk. After creation, it does not take up space; it increases with the accumulation of data, much like a subtle provision.
- 2. VirtualBox uses these formats: VDI, VMDK, VHD, HDD.
VDI is the main VirtualBox format.
VMDK is for VMware virtual disks.
There is also a division into fixed-size disks and dynamically allocated disks in VirtualBox, as in Hyper-V.
It is possible to convert fixed disks to dynamic disks for Hyper-V and VirtualBox.
Hyper-V vs VirtualBox: checkpoints vs snapshots
Hyper-V and VirtualBox have their own technologies that allow you to save a certain state of the VM and, if necessary, return to the previous state.
For Hyper-V, this is a Checkpoint, and for VirtualBox, this is a snapshot. These technologies are useful for testing or updating programs, but using them as backups would be unacceptable.
A little more about these technologies:
- 1. Hyper-V has two main types:
- Standard checkpoints. There may be data inconsistency when creating such checkpoints.
- Production checkpoints. They allow you to lock the virtual machine to prevent write operations to the virtual disk using VSS (Volume Shadow Copy Service) for Windows-based virtual machines or the Freeze File System for Linux-based virtual machines. This avoids data inconsistency.
When creating a checkpoint, a differential virtual disk is created where all changes are recorded after the creation of the checkpoint. Delta virtual disks are in the same directory as the parent virtual disks.
- 2. The VirtualBox snapshot helps create a new differential virtual disk as a new VDI file. When you delete a snapshot, the differential virtual disk is merged with the parent virtual disk or several differential virtual disks are combined.
Snapshot recovery with DiskInternals
DiskInternals VMFS Recovery™ is an application that every owner of a virtual machine should have.
This application helps to recover VMDK files, pictures from damaged and faulty disks. VMFS Recovery™ automatically checks the current state of VMware VMFS data storage, RAID (if used), and volumes, and reads VMFS structures where possible. After searching for data, you always have the opportunity to see the stunning results for free. After that, just purchase a license to export data to remote storage devices. After more than 15 years of experience, 98% of customers are happy to purchase a license and have been actively using the application for many years. If you think that such an application is beyond your power, simply activate the Recovery Wizard and follow its instructions.
Instructions for DiskInternals VMFS Recovery are included:
Download and install the utility on your computer.
When you open the application on your computer, connect via SSH.
Left-click to open the disk and activate the disk scanning process.
When the results appear, find the necessary VMDK files and mount them.
Browse the VMDK file (absolutely free).
After that, buy a license on the site for DiskInternals VMFS Recovery, and you will be provided with a unique license key. It will give access to export files to remote media. It also then automatically activate technical support functions throughout the year.
Hyper-V vs VirtualBox: final analysis
Both hypervisors are good, but they have big differences. Depending on your requirements, use of a specific OS, etc., decide for yourself which technology is best for you. Indeed, Hyper-V is a type 1 hypervisor, and VirtualBox is a type 2 hypervisor. In addition, Hyper-V can only be installed on Windows systems, while VirtualBox is available for a wide range of platforms (Linux, FreeBSD, Solaris, Mac OS, Windows).
