The present work conducts a performance study of virtualization tools with the aim of giving support to choose the most appropriate tool for creating virtual environments on network servers. The tools were the subject of study VMware ESXi and Citrix XenServer. Thus, benchmark tools were used to analyze the behavior of virtualized machines, creating an overload on the demand of the same basic resources such as processor, memory and disk. The tests were divided into categories based on the resources analyzed, and applied testing two guest operating systems, Windows Server 2003 and Fedora 14. For each virtualization tool, was created five virtual machines, which were conducted performance tests, first with a virtual machine, then with two machines, then three, four and finally five machines running simultaneously. With the tests completed, was observed characteristics of each virtualization tool and make an evaluation on their performance, their limitations and behavior. Where it was observed that the choice of guest operating system influences the performance of virtualization tool chosen. Thus, for virtual machines guest OS Windows 2003 Server, the tool that performs best is the comparative Citrix XenServer. For virtual machines guest OS Fedora 14 would be the best choice VMware ESXi.
