Migrating virtual server to the Cloud with Amazon AWS

Posted by Xaus Xavier Nadal 17th on May 2014

Conduct a converter of a virtual machine from physical to virtual or virtual to virtual is a breeze with VMware Converter, as we have talked about it in other articlesBut now that many of you are making the move to the Cloud we show you other techniques to migrate virtual server to the Cloud and vice versa, from the cloud to your on premise environments.

But not all operating systems can be migrated and meet some prerequisites that we will see in the following link:

In this post we will show you how to migrate a server in a virtual infrastructure (On premise) that is in our infrastructure to a cloud environment (the cloud that we have chosen is Amazon as we quite like and some had to go). When we have much experience on Amazon see other options such as Azure or re-environments on premise and surely we will stay with Amazon, but it will be time and money will tell you definitively what environment is that we pay for and maintain (What to think of everything, air conditioners, cpd, painting, cleaning, light ...), the server will be migrated into a virtual environment based on VMware but also served with Citrix or Microsoft Hyper-V.

The benefits they currently have cloud environments like Amazon are paid for months and use, if you have a server off not pay for it (Well, .. more or less (keep in mind the Elastic IP, disks EBS, snapshots in S3, VPC, ....) Now I will explain later how these products work or while skipping asking with comments or via e you'll solved your doubts. Another of the benefits of these systems Cloud is that they are highly scalable, if we need more resources only expand the server is already in minutes have more CPU, more RAM, more disk even SSDs, or even more IOPS on a specific disk, if for example we want to set up a system of video streaming or game Mobile (app) and do not know how many users are going to have in the system and can not preveerlo may use methods like Auto-Scaling to start instances EC2 (Servers) of the same features that make Load Balancing between them and have unlimited resources to provide our customers the desired service, but best of all is that when customers stop using the application, game, or stop viewing the soccer match streaming these servers will go by turning off / removing and cost of the product will be only used.

But enough of both text and what we've really come to do.

Detect state of CBT in virtual machines

Posted by Xaus Xavier Nadal 12th on September 2013

Long time no write but I do not have time to do it (Sorry).

The title of this article for those who have no notion of parameterization of virtual machines will be a little out of context, but for system administrators working with differential backups of virtual machines for disaster recovery know that to perform a differential backup vmdk disk is a need to have CBT enabled and thus not go every day copying all vmdk disk to disk or tape.

To detect if we have enabled CBT there are several ways to do this as in the article I did a while ago but those were different times and had no current knowledge about these systems, so I show below a more professional way to detect the status of CBT in virtual machines from the command line with powershell and PowerCLI for vmware modules.

I hope you like the script to other tasks since the beginning of the script to row 25 is to make a connection to ESX or Virtual Center and 25 line is the script itself to detect the status of CBT.

      1:    #################################################
      2:    # Detect state CBT (Change Block Tracking) #
      3:    #################################################
      5:    Add-PSSnapin VMware.VimAutomation.Core
      7:    function Read-HostMasked ([string] $ Prompt ="Enter password:") {
      8:      $ Password = Read-Host -AsSecureString $ prompt;
      9:      $ BSTR = [System.Runtime.InteropServices.marshal] :: SecureStringToBSTR ($ password);
  10:    $ Password = [System.Runtime.InteropServices.marshal] :: PtrToStringAuto ($ BSTR);
  11:    [System.Runtime.InteropServices.Marshal] :: ZeroFreeBSTR ($ BSTR);
  12:    return $ Password;
  13:  }
  14:  write.
  15:  write "**************************************"
  16:  write "Starting authentication process * *"
  17:  write "**************************************"
  18:  write.
  19:  $ Server = read-host "Enter vCenter, ESXi or IP"
  20:  $ User = read-host "Enter user"
  21:  $ Pwd = Read-HostMasked
  23:  Connect-VIServer $ server -User -Password $ pwd $ user -Force | out-string
  25:  Get-VM | Get-View | Select Name, @ {N = "ChangeTrackingStatus . "; E = {$ _}} Config.ChangeTrackingEnabled

When you know that CBT is enabled you also have to know that if you do not have a version of virtual machine or above 7, CBT will not work, the version of ESX therefore must exceed 4.0, NFS is not supported, nor RDM virtual compatibility mode.

You know that you can comment on what you like about this article or other blog, greetings and see you soon.

differential and incremental copies occupy the same as the FULL

Posted by Xaus Xavier Nadal on June 12th 2013

The differential backups as we all know are copies of the differences with a FULL copy.

Perform incremental backups copy of the differences since the last full or last incremental or differential.

In today's virtual environments where we copied completely virtual servers, virtual machines have a feature called Change Block Tracking that makes it possible to make only the copy of the modifications in the memory blocks and in this way occupy only a very small space by reducing the copying time and the occupied space, BUT there are times that this is not configured if we come from previous versions of Vsphere 4 for example, when updating the ESX environments, these values ​​are not created and must be done manually.

In this article we will show how Change Block Tracking enabled on a virtual machine

To do this we must do with the Virtual machine off.

We must edit the configuration of the virtual machine by right-clicking on the virtual machine and clicking on Edit Settings.

click on Hard Disk 1.

Mentally point the value of each SCSI disk created in the virtual machine: SCSI (0: 0), ...

Useful applications for VMware environments

Posted by Xaus Xavier Nadal 12th on May 2013

Today we are going to show several useful applications for VMware, these apps are free and do not require much knowledge to use.

Some of them are quite powerful and as you will see are continuing to substitute existing VMware environments in applications, but in some cases improved by the community. It's amazing what programmers can do with a good base of knowledge and with your imagination.

UBERAlign, IOMETER, and ESXI-customizer


And finally, the best of 3, UBERAlign is a Windows application by or through an appliance (OVA) allows us to align Vmware vmdk disks of virtual machines with disk array which is mounted and the system vmfs windows for example.

2 consists of parts, the client and the virtual machine..

In the case of creating vmdk disks using the Virtual Center problem in the vmdk not exist, but instead of mounting windows 7 or Windows Server 2008 assemble an older operating system the vmfs system will not be properly aligned and have the possibility of increasing the disk performance if we use this tool.

They say that we can expect to earn between 9 13% and performance in virtual infrastructure.

With UBERAlign we can first diagnose whether we have a failure of alignment and then resolve it if you think fit.

But this tool goes further, also achieved if we needed reclaim space that we are not using in virtual machines and after transforming discs to thin to have this space on LUN to accommodate more machines, you can see in the following video .

Until you takes a snapshot of the virtual machine if there is a problem in the process.

If you want to see why it is important to explain the alignment you perfectly in the following link:

You can see more advanced information on the following link


The first application we show is Iometer which you can download from the following link: application is open source and is not only useful for VMware environments, but for environments where we have a SAN, NAS, iSCSI, or even local disks back to store our data, computers or servers, this app serves as you said the word to measure disk IOPs we want, but we can also see the response times and MBs per second and other data.

When running the application will allow us to select the disks we want or even access to network drives by 5 top menu icon.
