This document discusses virtualization and virtual machines. It provides details on popular hypervisors like VMware ESXi, Citrix Xen, Oracle VirtualBox, and Microsoft Hyper-V. It also discusses components used for virtualization like VMware Workstation, ESXi Hypervisor, Ubuntu, and Windows Server. The document then explains metrics to measure computer performance like GFLOPS and LINPACK. LINPACK is used to estimate how quickly a system can solve real problems. Some advantages and disadvantages of LINPACK are provided. Results from testing ESXi, Hyper-V, and other hypervisors using LINPACK with 8000 operations are also summarized. Finally, the document discusses security best practices for hypervisors and guest operating systems.

3. 3
 Vmware- VMware dominates the server
virtualization market.
• ESXi- Type-1 hypervisor
 Citrix xen- microkernel design, Type-1
 Oracle- Virtual box
• Hypervisor for x86computers, Type-2
 Microsoft Hyper-V
• Windows Server Virtualization, Type-1
• Starting with Windows 8
• Consist of Win Server 2008 core and Hyper-V role

4.  Components Used-
• VMware Workstation 11.0
• ESXi Hypervisor 6.0
• Ubuntu operating system14.04
• vSphere Client
• Windows server 2008 R2 x64
• Hyper-V
 What to measure?
• Giga Floating Point Operations Per Second –GFLOPS-109 flops
• It is used to measure computer performance

 LINPACK- Intel corp. ,originally developed by
Jack Dongarra
 Main objective - To estimate how quickly the
system can solve real problems.
• Measures amount of time to perform
• Performance Rate
• It uses Partial Pivoting
• SMP Parallelism
• LINPACK package

6. 6
 Advantages-
• Used to measure speed in multiprogramming.
• It more accurate than other tools.
• Can compare one PC with other.
• Virtual Machine performance
 Disadvantage-
• It does not adapt itself according to the
instance specification.
• Not fully utilize complete set of resources

8. 8

9. 9
 Result for 8000 operations, LDA-8000 4
Align, 4 Trials
 ESXi is best in performance.

10.  Hypervisor Security-
• Enable Firewall.
• Network File System.
• Putty for secure login
 Guest OS security-
• Check security updates regularly.
• Enable Firewall in guest OS.
• Check system logs regularly.
