Hyper-V removed from OpenStack

Friday, February 3rd, 2012, by Erik Scholten

The new version of OpenStack, which will be released in Q2 of 2012, does not support Microsoft Hyper-V anymore. The developers have had enough with the buggy code.

One of the developers of OpenStack has written a patch with which the Hyper-V code and support will be removed from the cloud platform. The patch has already been approved and constitutes a part ofthe next version of OpenStack, codename Essex, which is expected to be released in Q2.

At the end of 2010 Microsoft announced that they would deliver code which would enable the use of Hyper-V in a cloud solution based on the open-source cloud platform, OpenStack. Microsoft never finished and maintained this, causing the code to be full of errors. After people in the OpenStack-forum suggested to remove the Hyper-V code, Microsoft quickly released a statement saying “Microsoft is committed to working with the community to resolve the current issues with Hyper-V and OpenStack“. However, the OpenStack developers decided not to wait until Microsoft finally fixed their code and decided to remove Hyper-V support with the new release.

OpenStack, Founded by Rackspace Hosting and NASA, is a global collaboration of developers and cloud computing technologists producing the ubiquitous open source cloud computing platform for public and private clouds. The project aims to deliver solutions for all types of clouds by being simple to implement, massively scalable, and feature rich. The technology consists of a series of interrelated projects delivering various components for a cloud infrastructure solution.


Trend Micro Deep Security 8 available now

Thursday, February 2nd, 2012, by Erik Scholten

At VMworld last year Trend Micro already announced their new version Deep Security 8, but now it is finally available.

Deep Security is specifically designed for virtual environments. Its agent-less architecture addresses AV storms, minimizes operational complexity of security and allows organizations to increase VM densities and accelerate virtualization and cloud adoption. Developed in close collaboration with VMware, Deep Security 8 is the first product in its category to offer support for VMware vSphere 5.0 and VMware vShield Endpoint 2.0.

But what’s new in Trend Micro Deep Security 8?
First of all it supports vSphere 5, so customers using Deep Security can finally upgrade their vSphere 4.x environments. Second, DS8 now offers agent-less integrity monitoring for greater virtual server security without added footprint. A third great new feature is a anti-malware agent which extends protection to physical server as well as VMware View environments using local mode.

RAID 5 and 6 support for VMware VSA

Wednesday, February 1st, 2012, by Erik Scholten

Yesterday VMware announced that it will be supporting RAID 5 and 6 with their Virtual Storage Appliance (VSA).

With the release of vSphere 5, VMware also released their VSA, a shared storage solution for the SMB market. VMware VSA uses the local storage in each ESXi server, presents it to the VSA appliance which in turn serves it back to the ESXi servers as shared storage.  Each ESXi server needs to run a VSA appliance, and each will contain a replica of the other’s storage.

Until now the VMware VSA only supported RAID 10, which resulted in very low storage utilization. Running VMware VSA with mirroring between two ESXi server, meant that you could only use 25% of your actual storage capacity.

Now with the added support for RAID 5 and 6, VMware VSA offers a greater storage utilization rate.

VMware vCloud Director design guidelines

Tuesday, January 10th, 2012, by Erik Scholten

After VMware vSphere and View, VMware vCloud Director is the next big thing to setup and customers start asking for it. But the problem is that the knowledge and available resources are limited. So for real life implementations of vCloud Director we have to rely on VMware employees to show us the ropes.
First of all, what is VMware vCloud Director. In short, VMware vCloud Director gives enterprise organizations the ability to build secure private clouds as a base for a infrastructure-as-a-service (IaaS) solution. Coupled with VMware vSphere, vCloud Director delivers cloud computing for existing datacenters by pooling virtual infrastructure resources and delivering them to users as catalog-based services.

The vCloud Director architecture is shown below.

VKernel vOps 4.5

Thursday, January 5th, 2012, by Erik Scholten

On December 19th VKernel released version 4.5 of its vOps management software.

vOps 4.5 addresses the increasing volume of routine virtual machine management tasks in virtualized environments. This increase is caused by the enormous growth in the number of virtual machines. Nowadays we provision many more virtual servers than we ever had physical ones because they are easier and cheaper to deploy. All of these virtual machines require management tasks for maintenance.

The next step in virtualization is automation and vOPS 4.5 also cover this with the introduction of some new capabilities, like:

  • New Automation Features
    vOPS’ virtual machine management automation capabilities are enhanced with auto-deletion of abandoned virtual machine images, auto-merging of unused snapshots, an additional automated remediation for performance issues and auto-calculation of future resource requirements;
  • Automation Controls
    vOPS 4.5 also adds the ability to more finely control some automation processes. For example, virtual machines can be grouped, and then these groups set with minimum and maximum resource amounts that automated right-sizing will respect.

Additionally, vOps 4.5 introduces:

Happy & virtual 2012!

Saturday, December 31st, 2011, by Erik Scholten

This year has almost come to an end and what a year it has been.

During 2011 VMware released a lot of new great products like vSphere 5, View 5, Workstation 8, Fusion 4, Horizon App Manager, vFabric Data Director, etc.

We also visited some amazing events which resulted in great experiences and content. It was the second year VMworld visited Copenhagen and what an awesome VMworld it was. And at the end of the year we had a great dutch VMUG with a suprise visit of the MonsterVM.

Career wise, almost all of us started with our new employer, Imtech ICT, in 2011, bringing us new adventures and opportunities.

This all resulted in some great content which you all appreciate, according to the website statistics. We servered 1.3M webpages during almost 400.000 visits of 240.000 unique visitors, which resulted in 556GB of traffic. Great numbers with steady growth over the whole year.

We will keep up the good work and hope to see you again in 2012 to make it an even better year!
So, from all of us at VMGuru.nl, we wish you all a very happy and virtual new year!

Updated Enterprise hypervisor comparison

Tuesday, November 29th, 2011, by Erik Scholten

During the last few years we published several Enterprise Hypervisor comparisons and we got very positive comments and feedback on it. With the release of vSphere 5, XenServer 6 and a service pack for Hyper-V it was time for an update.

It very interesting to see how some of the products have improved over the years and how the three major manufacturers look at each other and copy features. But you can’t trust all manufacturers by just a simple green checkbox. Some claimed features need third party add-ons, aren’t suitable for production workloads or are only supported on a limited set of operating systems. You have to investigate further and I hope I’ve done most of that work for you with this new enterprise hypervisor comparison.

VKernel acquired by Quest

Friday, November 18th, 2011, by Erik Scholten

Just 15 minutes ago I heard the ‘news’ that, last Wednesday, VKernel was acquired by Quest Software.

VKernel will continue to operate as an independent subsidiary of Quest, building, selling and marketing the same performance and capacity management solutions. So, it will be business as usual for VKernel, except the new VKernel will be turbo-charged with the backing of Quest.

For the current customers, nothing changes. The same team that has built, sold, and supported your products is still here. The main difference is that VKernel now has the financial backing and support of Quest Software.


New ThinApp and Horizon Application Manager released

Friday, November 18th, 2011, by Erik Scholten

Last Wednesday, November 16th, VMware announced the availability of ThinApp 4.7 and Horizon App Manager 1.2. The combination of the two products enables cloud-based deployment of ThinApp packages with VMware Horizon Application Manager.

ThinApp 4.7 includes the following features:

  • The ThinApp Setup Capture wizard includes an option to manage with Horizon Application Manager. When the checkbox is selected, ThinApp checks if the Horizon agent is installed natively on the client and is running. If the Horizon agent is found, the ThinApp package reports to the Horizon agent so that it can be controlled by Horizon Application Manager.
  • Horizon Application Manager entitlement allows the delivery of ThinApp packaged applications to specified users and groups. The Horizon agent authorizes a ThinApp package to open, based on entitlements.
  • ThinApp packages are registered by Horizon Application Manager and delivered to end points.
  • The administrator can track usage of ThinApp packages by using Horizon Application Manager monitoring and reporting.
  • The administrator can configure an Organizational URL for end points missing the Horizon agent.

The return of VMTN?

Tuesday, November 15th, 2011, by Erik Scholten

Over the years there have been a lot of outcries in the VMware Community to re-instate the VMware Technology Network (VMTN).

The VMTN started in 2005 and is much like Microsoft MSDN or TechNet, for a reduced yearly fee you could use the VMware software and run it for 1 year. Unfortunately VMware canceled the VMTN  program in 2007, reportedly because they didn’t want developers to use it for competitive products.

Right now many developers and techies with home labs use evaluation versions which expire after 60-days.

So, according to VMware CTO, Steve Herrod, VMware is now considering the return of the VMware Technology Network and I think it’s a good initiative. Why?

VMware and Nvidia join forces

Friday, October 21st, 2011, by Erik Scholten

 

 

One of the announcements I missed at VMworld Europe 2011 in Copenhagen was the announcement of VMware and Nvidia delivering 3D graphics to VMware View. VMware announced that they are in a partnership with NVIDIA to deliver high-end virtual workstations with 3D graphics support in VMware View.

We’ve have the ability to deliver 3D graphics from workstations in the datacenter for years by using physical blade workstations. But now VMware is trying to deliver true 3D performance from the datacenter by using virtual workstation in VMware View by partnering with Nvidia. Nvidia is solving that with the release of their ‘Quadro Virtual Graphics Platform’, something they announced in August 2011.

One of most inspiring stories @ VMworld 2011

Friday, October 21st, 2011, by Erik Scholten

 

 

Yesterday was the last day of VMworld Europe 2011 in Copenhagen and I was wandering around at the VMware booth at the Solution Exchange. After a demo of VMware View with Unified Communications, I was introduced to Hanna Phan and according to the VMware employee, Hanna was the most famous person within VMware at the moment. Not Paul Maritz, Steve Herrod or Mauricio Carl but Hanna Phan.

The cool thing is, she only works for VMware for 3 weeks now. So how does someone become so famous, so fast?

Massive fight at VMworld 2011 in Copenhagen.

Friday, October 21st, 2011, by Erik Scholten

 

 

Yesterday the was some disturbance at VMworld Europe 2011 in Copenhagen. A massive fight broke out between the one-on-one rooms and the lounge area. Research shows that it was a reckoning of the dutch vMafia. Eye witnesses told us that six to eight mobsters beat the crap out of the Monster VM and we’ve managed to get hold of some video footage showing just that.

Bottom line, don’t mess with the dutch vMafia…


VMware vSphere clustering Q&A (VSP1682)

Wednesday, October 19th, 2011, by Erik Scholten

 

 

Today I attended session VSP1682 ‘VMware vSphere clustering Q&A‘ hosted by Frank Denneman, Duncan Epping and Chris Colotti.

After a short introduction the Q&A started and below you will find my top 10 questions.

Q1. Are the old, vSphere 4, constraints in vSphere 5 still current?

Until vSphere 5 the best practice is a maximum of 8 hosts in a cluster, because of linked clones in VMware View and the primary/secondary ESX(i) hosts setup in an HA cluster. In vSphere 5, VMware changed this to a master/slave setup. When the master ESXi host goes offline a new master is elected within 15 sec. So, the cluster boundary limits VMware vSphere had in the past are gone. This is a huge advantage of vSphere 5.0.
