RVTools is a windows .NET 2.0 application which uses the VI SDK to display information about your virtual machines and ESX hosts. Interacting with VirtualCenter 2.5, ESX Server 3.5, ESX Server 3i, ESX Server 4i, VirtualCenter 4.0, ESX Server 4.0, VirtualCenter 4.1, ESX Server 4.1, VirtualCenter 5.0, VirtualCenter Appliance or ESX Server 5.0. RVTools is able to list information about VMs, CPU, Memory, Disks, Partitions, Network, Floppy drives, CD drives, Snapshots, VMware tools, ESX hosts, HBAs, Nics, Switches, Ports, Distributed Switches, Distributed Ports, Service consoles, VM Kernels, Datastores and health checks. With RVTools you can disconnect the cd-rom or floppy drives from the virtual machines and RVTools is able to update the VMware Tools installed inside each virtual machine to the latest version.
Version 3.4 (September, 2012)
- Overall performance improvements and better end user experience
- VI SDK reference changed from 4.0 to 5.0
- Added reference to Log4net (Apache Logging Framework) for debugging purpose
- Fixed a SSO problem
- CSV export trailing separator removed to fix PowerShell read problem
- On vDisk tabpage new fields: Eagerly Scrub and Write Through
- On vHost tabpage new field: vRAM = total amount of virtual RAM allocated to all running VMs
- On vHost tabpage new fields: Used memory by VMs, Swapped memory by VMs and Ballooned memory by VMs
- Bugfix: Snapshot size was displayed as zero when smaller than 1 MB
- Added a new preferences screen. Here you can disable / enable some performance killers. By default they are disabled

5 Reasons to go to VMworld 2012 Barcelona
VMware has studied workloads from database, Java, multimedia, and encryption categories and report the results. Test results show that almost all workloads perform well even when the virtual machine presents an EVC mode that corresponds to an older processor generation. The EVC mode setting had varying impact on workload performance based on the ESXi hosts’ CPU instruction set features made available and their relevance to the workloads. One workload, AES-Encryption, didn’t fare as well due to a dependence on special-purpose instruction sets only available in younger processor generations.

This video features a discussion and demonstration of using the vSphere Web Client or PowerCLI to identify which virtual machines were impacted and restarted after an ESXi host failure. In this demo, our good friend Duncan Epping who is a Principal Architect within the VMware Technical Marketing team, goes through the various places where you can find some information and details concerning virtual machines that may have failed during the ESXi outage. For additional details, check out Duncan's or Graham Daly's blog posts.
Taking a top-down approach to vCloud Director design necessitates an understanding of the new abstractions introduced in the vCloud API and how they map to traditional VMware vSphere® objects. This paper was developed to provide additional insight and information as to how vCloud Director allocation models relate to vSphere resource management. The paper written by Frank Denneman and Chris Colotti reviews and discusses various design considerations and operational procedures.
