A type 2 hypervisor is more powerful, faster, and more secure than a type 1 hypervisor.
A hypervisor, also known as a virtual machine monitor or VMM, is a type of virtualization software that supports the creation and management of virtual machines (VMs) by separating a computer’s software from its hardware. Hypervisors translate requests between the physical and virtual resources, making virtualization possible. When a hypervisor is installed directly on the hardware of a physical machine, between the hardware and the operating system (OS), it is called a bare metal hypervisor. Some bare metal hypervisors are embedded into the firmware at the same level as the motherboard basic input/output system (BIOS). This is necessary for some systems to enable the operating system on a computer to access and use virtualization software. Show

VMware vSphere Hypervisor 7.0 U3b Download CenterThe term bare metal refers to the fact that there is no operating system between the virtualization software and the hardware. The virtualization software resides on the “bare metal” or the hard disk of the hardware, where the operating system is usually installed. Bare metal isn’t only used to describe hypervisors. A bare metal server is a regular, single-tenant server. However, it can be a host machine for virtual machines with the addition of a hypervisor and virtualization software. A
bare metal cloud refers to a customer renting the actual servers that host the public cloud from a cloud service provider, in addition to renting the public cloud services. The bare metal hypervisor is the most commonly deployed type of hypervisor. This is where the virtualization software is installed directly on the hardware, where the operating system is normally installed. Bare metal hypervisors are extremely secure since they are isolated from the attack-prone operating system. They perform better and more efficiently than hosted hypervisors, and most companies choose bare metal hypervisors for enterprise and data center computing needs.
A bare metal server is a dedicated server with a single tenant, controlled by a single client. For bare metal virtualization, that client can install a bare metal hypervisor directly onto the hardware of that server to enable virtualization technology including virtual applications, multiple virtual machines, or private clouds.
Is Type 1 or Type 2 hypervisor more secure?The native hypervisors are a more secure option. Unlike the hosted hypervisor, they do not depend upon the underlying OS. So if under attack, you have better chances with the bare-metal hypervisor (Type 1). This dependency also costs the type 2 server, a little bit of its efficiency, performance, and speed.
Is a Type 1 hypervisor more secure?Pros: Type 1 hypervisors are highly efficient because they have direct access to physical hardware. This also increases their security, because there is nothing in between them and the CPU that an attacker could compromise.
Why are Type 1 hypervisors more secure than Type 2 hypervisors?Type 1 hypervisors are also known as bare-metal hypervisors, because they run directly on the host's physical hardware without loading the attack-prone underlying OS, making them very efficient and secure.
Which type of hypervisor is faster?Bare metal hypervisors are faster and more efficient as they do not need to go through the operating system and other layers that usually make hosted hypervisors slower. Type I hypervisors are also more secure than type II hypervisors.
