Question

Select two hypervisors on the market today, and compare and contrast how they virtualize and manage the underlying hardware (CPUs and memory).

a) VMware vs. VirtualBox
b) Hyper-V vs. KVM
c) Parallels vs. Xen
d) Docker vs. Vagrant

Answer 1

VMware and VirtualBox are both hypervisors that manage hardware, with VMware being a type 1 hypervisor and VirtualBox a type 2 hypervisor. Hyper-V and KVM are also hypervisors with different features.

Step-by-step explanation:

VMware and VirtualBox: Both VMware and VirtualBox are popular hypervisors that virtualize and manage the underlying hardware. VMware ESXi is a type 1 hypervisor, which means it runs directly on the host hardware, while VirtualBox is a type 2 hypervisor, which runs on top of the host operating system.VMware ESXi offers advanced features like vMotion, which allows live migration of virtual machines between hosts, and Distributed Resource Scheduler (DRS), which optimizes resource allocation. VirtualBox, on the other hand, is known for its ease of use and wide compatibility with various operating systems.

Hyper-V and KVM: Hyper-V is a type 1 hypervisor developed by Microsoft, while KVM (Kernel-based Virtual Machine) is a type 2 hypervisor used primarily in Linux-based operating systems. Both hypervisors provide virtualization and hardware management capabilities.Hyper-V offers features such as live migration, memory management, and integration with Microsoft systems. KVM, on the other hand, leverages the Linux kernel to provide virtualization capabilities and supports various operating systems.
