Updated: RVTools 3.4 for vSphere

The best free inventory tool for vSphere has been updated!


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 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 Updates (3.4) are as follows:

  • 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

Montreal VMUG: Post-Event Blog (Sept 20th, 2012)


I would like to thank everyone for making the Sept 20th Montreal VMUG a success!  Below are the links and presentations that were highlighted at the #MTLVMUG.

Oracle Licensing on VMware: The truth is revealed!

One of the main pain points of virtualizing Oracle is not the technical aspect of it (there are tons of technical white papers that can help you with that), but instead, licensing.

VMware always defended that fact that their host affinity rules along with vMotion logging is a valid way of partitioning clusters for licensing purposes. Oracle sales reps and licensing whitepapers have always defended that VMware’s partitioning (unlike OracleVM) is not recongnized has “hard partitioning” but rather soft partitioning, although OracleVM uses a very similar technique to keep the VMs on specific set of hosts in a cluster.

This being said, Richard Garsthagen, Director of Cloud Business Development EMEA for Oracle has publicly stated  that VMware’s host affinity rules and vMotion logging (used inclusively) are valid for purposes of establishing where Oracle software is “installed and/or running” for purposes of the Oracle Software License Agreement (OSLA).

Want proof? Watch the video below.

Now here is the kicker. Oracle requested a takedown of that video, although it is still up on youtube, it has been unlisted and can only be access directly via a link. Oracle has also updated their Virtualization Blog with a statement that “clears up” misconceptions from VMworld 2012.

The team from (probably the team that conducted the interview with Richard Garsthagen) have done research on this issue and have stated the following on their BLOG.

-that your definition is pointing out that you need to license those processors where the Oracle software is installed and/or running.
-no useless whitepaper, LMS or Salesrep should convince you otherwise.
-external lawyers support this position.

Hopefully, spreading the word on this issue will help rattle some cages and maybe one day we may have some consistent answers from Oracle.

What’s New with VMware vSphere 5.1

Once again, another VMworld has passed and as usual, VMware does not disappoint with the announcement of vSphere 5.1 and a slew of new features. The following is a summary of all the latest additions and improvements to vSphere. In addition, below are the PDF links to VMware’s technical documents that give you a deep dive and talk about other minor but still important features. Spread the word, retweet and Enjoy.


• Larger virtual machines :  64 vCPU and 1TB RAM

• Version 9 of VM Hardware: Better graphics and CPU performance counters


• Flexible, space-efficient storage for virtual desktop infrastructure (VDI)


• vSphere Distributed Switch: Network health check, switch config backup/restore, LACP support

• Single-root I/O virtualization (SR-IOV) support


• vMotion: No shared storage required!

• Data Protection: EMC Avamar backup platform replaces VMware Data recovery software.

• vSphere Replication: RPO as low as 15 minutes.

• Zero-downtime upgrade for VMware Tools: No reboots! One of my favorite features.


• VMware vShield Endpoint: Improvements


• vSphere Storage DRS and Profile-Driven Storage: New integration with vCD, further efficiencies and automation in private cloud environment.

• vSphere Auto Deploy: Two new methods for auto deploying hosts.


• vSphere Web Client : Looks amazing, The vSphere Web Client is now the core administrative interface for vSphere.

• vCenter Single Sign-On: access all instances or layers of vCenter with SSO authentication.

• vCenter Orchestrator: Newly designed workflows enhance ease of use, and can also be launched directly from the new  vSphere Web Client


• No more vRAM licensing, no CPU core limits, 1 license per socket, that’s it!
