Introduction to VMware vSphere Hypervisor

VMware vSphere Hypervisor from VMware is a bare-metal, free hypervisor. It enables users to virtualize consolidate applications and servers. This hypervisor has been there since 2008. At that time, this hypervisor was known as Free ESXi 3.5.

The hypervisor lacks certain enterprise-grade characteristics of the complete VMware ESXi version, like Storage vMotion, vMotion, Distributed Resource Scheduler, vSphere Data, and High Availability. However, the hypervisor includes:

  • Restore and snapshot capabilities
  • Thin provisioning of VM disks
  • Virtual guest OS support
  • Hardened device drivers
  • vSphere client’s support
  • Over-commitment of the memory
  • Support for iSCSI, NFS shared storage and Fibre Channel

People can upgrade to various advanced versions of the VMware vSphere Hypervisor after adding a license file.

Part 3: How to Install VMware vSphere Hypervisor

Users can easily install VMware vSphere Hypervisor on their own or with some help. If they are in search of a DIY approach, then download the installer and accept the end-user license agreement. After this, they can choose which local drive they like to install this program on.

Create Virtual Machines

After you have installed VMware vSphere Hypervisor, there are lots of methods to create VMs. Here, we are listing three different ways to perform this task. So, have a look at them below!

  • Employ the VMware vCenter Converter for transferring existing servers into VMs. Or, one can even import third-party VM images and existing VMware.
  • Produce virtual machines from the start by specifying the amount of memory, disks, number of CPUs, and network interfaces required. After that, one has to load the operating system from a boot disk or ISO images.
  • Import virtual appliances and there are lots to select from on the VMware Solution Exchange.


After you have imported or installed the virtual machines, you will require configuring them. For getting started, you can refer to the configuration and installation video within the section ‘Resources‘ on the official website of vSphere Hypervisor. In case you need support, it is best to purchase Per Incident Support for vSphere Hypervisor.

Upgrade to VMware vSphere

As you move up to the paid vSphere version, it lets you optimize the IT infrastructure further. Once you got hands on it, you will be able to do the following things:

  • Storage and pool computing resources across various physical hosts.
  • Enjoy centralized management of several hosts via VMware vCenter Server.
  • Take benefit of business continuity, advanced backup, automatic load balancing, and restore capabilities for the virtual machines.
  • Carry out live migration of your virtual machines.
  • Deliver enhanced operational efficiency and service levels.

Part 4: Get Acquainted with Platform Integrity Protection

Secure Software Packaging

VIB (vSphere Installation Bundle) is an ESXi software package. CIM provides, VMware and its package solution partners, applications, and driver, which extend the ESXi platform, these all are packages as VIBs. vSphere Installation Bundles are usually present in software depots. People can employ VIBs for creating and customizing ESXi ISO pictures or for upgrading ESXi hosts through installing the VIBs onto the hosts. Every VIB comes up with a rating known as an acceptable level. This acceptance level regulates which VIBs could be installed to a host. It is guaranteed by a digital signature. VMware supports several acceptance levels, such as Community Supported, Partner Supported, VMware Accepted, and VMware Certified.

Software Integrity and Assurance Protection

vSphere employs Intel Trusted Execution Technology/ Trusted Platform Module (TXT/TPM) for providing remote attestation of the VMware vSphere Hypervisor image depending on a hardware root of trust. The image comprises of several elements like third-party VIBs, ESXi software in VIB format, and third-party drivers. For leveraging this capability, the ESXi system should have TXT and TPM enabled. When TXT and TPM are enabled, the software measures the complete Hypervisor stack while the system boots. The software stores the measurements in the TPM’s PCRs (Platform Configuration Registers).

The measurements comprise of the kernel modules, native management applications running on ESXi, VMkernel, drivers, and other boot-time configuration options. The measurements for all the installed VIBs are exposed in the vSphere API. As stated by the Trusted Computing Group, the API provides an event log. After comparing the image to the expected image, a third-party solution could leverage this very feature for detecting the Hypervisor image’s tampering.

Please note that people should utilize third-party solutions for entirely leveraging vSphere TXT/TPM baseline support aimed at Hypervisor attestation. This is because vSphere does not offer a user interface for viewing the measurements.

Part 5: Know About VMware Secure Development Cycle

For improving the products’ security, VMware vSphere Hypervisor employs various techniques throughout the software development cycle. The standard techniques, employing external and internal expertise, comprise static code analysis, threat modeling, penetration testing, and incident response planning. VMware features an established Software Security Engineering Group, which integrates the techniques into the development cycle. It even offers guidance on the recent security threats, security expertise, defensive techniques, and exercising in the development organization. The group is even responsible for moving VMware products via external security certifications and accreditations.

VMware vCenter Server 5.0 and vSphere 5.0 attained Common Criteria certification at EAL4+ (Evaluation Assurance Level 4) within the CCEVS. This international set of guidelines offers an average framework to evaluate the security capabilities and features of IT security products. Before the reform in the Common Criteria certification scheme, EAL4+ used to be the highest recognized assurance level under the CCRA (Common Criteria Recognition Agreement). The Criteria evaluations transit from EAL levels to protection profiles. With time, these profiles get available, and EAL levels disappear, and the products will get evaluated against the safety requirements defined by protection profiles.

There’s a virtualization profile to which vSphere evaluations in the future will conform. Until the protection profiles become present for every particular technology kind, security evaluations based on targets will be acted at EAL Level 2. VMware vSphere 5.1 is being measured at EAL Level 2. If you like to know more about EAL2 vs. EAL4 and also about protection profiles pertaining to vSphere 5.1. Or other products from VMware, it is best to refer to the VMware Common Criteria Update blog.

VMware Security Response Policy exhibits the commitment of VMware for resolving vulnerabilities related to VMware products. Thus, it assures its customers that any issue like these will be corrected quickly. The Security Center of VMware is an all-in-one stop for issues linked to security that involves VMware products. This helps clients to keep an eye on all security problems and to comprehend matters associated with protecting the virtual infrastructure.
