You can temporarily suspend the guest operating system to resume from a specific point, but it isn't the same as creating an image history for the virtual machine. Each hypervisor allows you to drag and drop files between the host and guest operating system. VirtualBox and VMware Workstation Player both use seamless mode to integrate the virtual machine environment into the host operating system. Seamless mode strips away the additional virtual machine window and menus, making it feel like the guest operating system is part of the host.
If you want to encrypt your virtual machines, you're in luck. Each hypervisor supports encryption of one kind or another. So long as your hardware can run the guest operating system without destroying the host in the process, you can use the free virtual machine software. Whereas, Windows Hyper-V is also free but only if you have the correct version of Windows 10 or Windows There are workarounds for Windows 10 and Windows 11 Home users desperate to use Hyper-V on their hardware.
But those people may as well use one of the free alternatives rather than shoehorn a solution. Don't forget, the fix might work today, but it might not with the next Windows update. Windows 10 Hyper-V has some limitations regarding guest operating systems. It does not support macOS. Please note that a macOS guest operating won't work out of the box. If you have a powerful machine running Windows 10 or Windows 11 Pro, Education, or Enterprise, you can take your pick of the hypervisors.
It offers better support and stability for a wide range of hardware. What are virtual machines used for? In contrast, Client Hyper-V uses only hardware-assisted virtualization. At one time, Microsoft did support software virtualization through a product called Virtual PC. Hyper-V can only run on Windows family operating systems and it is available as a built-in feature from Windows 8 onwards and as a server role from Windows Server to later versions — it can host VMs with Windows, Linux, and FreeBSD guest operating systems.
If you are in a Windows-only environment, Hyper-V is the only option. But if you are in a multiplatform environment, then you can take advantage of VirtualBox and run it on any operating systems of your choice. Hyper-V Integration Services is a set of drivers and utilities that are installed in the guest OS to improve overall performance and also to improve the interactions between the host and guest operating systems.
VirtualBox Guest Additions is again a set of drivers and utilities similar to that of Hyper-V Integration Services, to optimize the performance and usability of the guest OS. VirtualBox also supports Fixed and Dynamic disk allocation. A Hyper-V checkpoint is the same idea as the popular Windows restore point that many Windows users have utilized before adding new applications or making other system changes to their machines.
Hyper-V checkpoints allow users to easily save the current state of a virtual machine before making any critical changes so that if a problem crops up due to the changes, the VM can be reverted to its previous state. After creating the checkpoint, all the changes made are written to the differencing disks and those are stored along with parent virtual disks in the same directory.
VirtualBox snapshot is an equivalent of Hyper-V checkpoint that allows you to save and then revert back to the exact state of a virtual machine. Hyper-V is a type 1 hypervisor, which runs on computer hardware.
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. Hyper-V supports only Windows, starting with Windows 8 and later.
Teleporting is available from VirtualBox version 3. Migration of running VMs improves the flexibility of your virtual environment. Hyper-V supports hardware virtualization. Hardware virtualization is a technology that uses a hypervisor to create an abstraction layer between software and physical hardware for emulating computers.
All devices needed for the proper functionality of a computer are emulated with special software. VirtualBox supports hardware and software virtualization. Software virtualization can only be used for VMs with bit guest operating systems that use x86 architecture. For bit guest systems, only hardware virtualization may be used. You can create, import, configure, start, stop, and remove VMs with Hyper-V Manager, as well as perform other actions such as configuring virtual switches, virtual hard disks, creating checkpoints, connecting to the guest OS interface with VMConnect, etc.
Hyper-V servers can be managed with PowerShell, which is a Windows command line interface developed by Microsoft.
PowerShell Remoting must be enabled for this purpose. Another advantage is the ability of scripting and automating. Port Mirroring is a network traffic analyzing tool for Hyper-V. This feature allows you to send copies of all received and transmitted packets from one port to another for further packet analysis.
The main purpose of using Port Mirroring is troubleshooting. You can create a VM that has a virtual network adapter connected to the appropriate virtual switch port, install packet analysis software on that destination VM, and send network packets from multiple VMs to the destination VM for analysis. VirtualBox provides a network tracing feature with which you can enable network packet logging for further analysis. Later you can open these files in the traffic analysis tool such as Wireshark.
This feature can be activated with a command line interface. Disable this feature after finishing investigation to prevent filling out the whole disk with PCAP files. Shared folders are useful for file exchange between different machines. Hence, this approach can be used for copying files from a host OS to a guest OS, and vice versa. You can also use a Copy-VMFile PowerShell tool in Hyper-V virtual environments as an alternative method to copy files between physical and virtual machines.
VirtualBox includes a built-in Shared Folders feature that can be easily enabled from the VirtualBox user interface. Transferring files between VirtualBox host machine and guest machine by using Shared Folders is convenient. If needed enable or disable the following options: Read-only, Auto Mount, and Make Permanent by checking the boxes.
