VMware ESX: Alarm configuration for VMware VI3 (ESX)

A feature that VMware VI3 offers and that is definitely worth the ten minutes it takes to configure are the alarms. VMware VI3 gives us the opportunity to receive alarms (via a script) or be notified (by mail, SNMP) for changes in certain parameters of our VM.

The alarms indicate the status of objects, which can be: folders, datacenters, clusters, resource pools, and hosts and VMs. In fact, on the left side of the VMware Virtual Center, you can see these objects and their hierarchy.

The first thing we have to do is decide what level we want to set the alarm that we are going to configure at. Personally, I felt comfortable setting mine to Clusters & Host. In this way, setting a couple of alarms is enough for all of my VMs. If one particular VM or parameter that is not specifically monitored with the above-mentioned alarms interests me, I can set another alarm for it. This, however, does not happen often.

There are only two alarms that I would like to set for Hosts & Clusters: one type is an Alarm Host and the other is an Alarm VM. This will allow me to know what is happening to the Hosts and VMs I have in my virtual infrastructure.… Read More

VMware ESX 4.0 FT – Fault Tolerant – Sneak Peek

VMware innovations in operation continuity will be glowing in VMware ESX 4.0.In addition to the current high availability of VMware ESX Server, the software will inherit a function of fault tolerance.Today, VMware High Availability (HA) provides rapid restart of virtual machines in their last known state on a different ESX server, in case the physical server hosting them face a failure.

With VMware FT (Fault Tolerance), the system provides synchronous replication of protected VMs on two different servers.The application continues to function without interruption on the secondary server if the primary server comes to fail.For additional security measure, this cloned VM is automatically replicated to a third server, as the first server is not repaired, to maintain the availability of the VM if the second server also came to the same problem.

Meanwhile, the launch of VMware FT, the only real solution for fault tolerance available in virtualized environment remains hidden and not announced. Thought it was of a great deal that I thought I will share it with everyone, even before it hit the market. To get you more exited about VMware FT check out the below VMware FT Video:

Microsoft validates the VMware ESX Hypervisor

Now Microsoft offers technical support to customers who run the virtualization tool with Windows Server.

VMware, the clear leader of server virtualization, has announced that its VMware ESX hypervisor meets the requirements of Microsoft’s Server Virtualization Validation Program (SVVP). VMware ESX 3.5 update 2 (ESX 3.5u2) is the first hypervisor to join the program, which provides support from both Microsoft and VMware to customers who work with Windows Server and Microsoft applications. “Virtualization is already established within a stream of IT and our relationship with Microsoft shows just how far it has come, providing users of VMware ESX access to valuable support for their virtualized Microsoft applications,” says Bogomil Balkansky, Senior Director of product marketing at VMware. “VMware and Microsoft are working together to make sure that our joint customers enjoy the benefits of virtualization with the reassurance that professional support provides,” he adds.

Microsoft’s Server Virtualization Validation Program enables VMware and other software vendors to test and validate that their virtualization tools run well with Windows Server 2008 and previous versions. Through this program, Microsoft provides technical support to joint customers who run Windows Server on validated virtualization software that is not Microsoft’s, such as VMware ESX 3.5… Read More

Microsoft vs. VMware: Companies lose the battle – Part 2

Signs of an immature market

But is it really necessary for hypervisors to be a proprietary technology? Efforts by Microsoft and VMware to differentiate their hypervisors remind us of the networking situation thirty years ago, when all power suppliers believed in different technologies (Token Ring, Ethernet, ARCNET, etc.). Gradually, however, manufacturers have accepted the idea that taking a common standard (TCP/IP over Ethernet) and concentrating their efforts on innovation in the upper levels of the software stack, stimulates the growth of the market as a whole and, consequently, the value of the manufacturer’s own share of the pie. It seems that in the case of virtualization, suppliers are not yet ready to see the situation from this perspective. Today, speeches still revolve around concepts such as speed and feeds, but probably the market itself will finish by imposing its own rules.

If all server-based computers are in the early stages of a massive migration towards virtual machines, as many analysts argue, the lack of a standard hypervisor for Windows will only delay this transition. The fact that manufacturers focus on being different and unique shows that virtualization is still an immature business. The problem is that, despite this immaturity, many companies are already dependent on virtualization.… Read More

How-To: mount Windows Share under VMware ESX Service Console

Have you ever wanted to transfer files & ISO between your windows Machine & your ESX Server Service Console?

This come to be handy when you want to keep your Operating systems & other software ISOs on the storage, so you can use them for virtual machine installation & configuration for later time. Did you know installing a vmware machine from an ISO on storage usually take less than half the time if you were using a real media CD.

To achieve this goal you have two methods. Either you make Windows share accessible to the Service Console as illustrated in the following article how to mount windows share under vmware esx .

The second method is to share your NFS partition from the service console and mount it under windows. This can be achieved as well as illustrated in the following article Using Windows-based NFS in VI3.

I hope this was helpful to everyone.… Read More

VMware VI3 Root Shell Access

VMware wants to re-motivate its troops

VMware has announced several major improvements to its partnership program VMware VIP, which relates to nearly 10,000 partners around the world. The improvements include the Advantage+ Incentive Program, which offers higher margins to partners and reward their efforts with those concluded pro-actively sales of products and solutions VMware, sold to new customers or those who initiated negotiations even if another partner who makes the sale. VMware wants to make better use of its partners, but it is a wonder why this initiative? and why now?

From there you think that the No. 1 in the virtualization market is trying to re-motivate the troops who are increasingly hearing sirens of Microsoft and Citrix/Xen, it was a step … However, products VMware have still early to be too worried about, if one believes the craze still vivid of CIOs for ESX technologies.

What’s new in VI3.5?

The VMware team few days back has a very short Webinar on “What’s New in VMware Infrastructure 3.5”. I have missed some of the points, but below are the most important things that have been raised:

vmware vi3.5 whats new

ESX Server 3.5 & 3i:
The 3i server will be next generation to the “normal” ESX a decisive strategic plan. End of the year, the first hardware manufacturer will start releasing servers with the 3i server pre-installed. The list price of 3i is $ 495 for 2 CPUs. In the long run, the ESX3i seems to be the replacement for ESX3 stripping the Service Console!

Distributed Power Management:
This feature is an enhancement for the existing DRS. It will power down unoccupiedphysical hosts (to spare electricity) and, power it on if necessary, again!

improved HA:
HA is now no longer limited to hardware failure of a physical hosts respond, but also hanging VMs restart. This will be implemented using the vmware-tools and the associated Heard beat. Thus, each supported VM OS is supported – it is allowed to be curious whether the thing in practice really works!

Storage VMotion:
So far VMotion was only between machines sharing the same storage. If you had to move a VM between different storages you had to turn off the VM then clone it (Basically required down time).
