Within the cloud and virtualization space, a lot had happened in last one week or so. I am still catching up on all the news but one thing that caught my attention was the announcement around vRealize Automation 7.0. I recently started working on the vRealize suite of products and therefore this announcement was completely relevant. There are a ton of new features in this release. Especially, things like the simplified install wizard (you will appreciate this if have you installed IaaS in earlier versions of vRA), graphical service blueprint designer and integration with source control. You can read more about these new features on VMware blog at: https://blogs.vmware.com/management/2015/10/vrealize-automation-7-0.html. While you are there, sign-up for download availability notification and get your hands dirty when you get the product.
Over the weekend, I was looking at a way to install the VMware vCenter Server Appliance 6.0 update 1 from command line. The process is straightforward. We generate a template (JSON) file with all required parameters and give it to vcsa-deploy.exe in the .\vcsa-cli-installer\win32 folder of the mounted or extracted ISO. For me the real problem was when I started using vcsa-deploy.exe. It started throwing errors just after the JSON validation and while logging into the ESX host specified in the JSON template. 2015-10-04 17:59:44,875 – vCSACliInstallLogger – ERROR – An error occurred when connecting to “ESX-1”: Failed to login to host ESX-1, as user root: [Errno socket error] [Errno 8] _ssl.c:499: EOF occurred in violation of protocol 2015-10-04 17:59:44,875 – vCSACliInstallLogger – DEBUG – The vCenter Server Appliance installer log file is at: c:\users\admini~1\appdata\local\temp\2\vcsaCliInstaller-2015-10-04-12-29-wgyrvy\vcsa-cli-installer.log 2015-10-04 17:59:44,875 – vCSACliInstallLogger – DEBUG – The vCenter Server Appliance installer result file is at: c:\users\admini~1\appdata\local\temp\2\vcsaCliInstaller-2015-10-04-12-29-wgyrvy\vcsa-cli-installer.json I spent sometime looking around for help and tried things like enabling SSH on the ESX host and so on. When nothing solved …
n this post, I am making an update to the original script available. There is just a minor update to the logging mechanism. You can now choose to log all the success / fail events to Windows application event log instead of a text file.
I keep getting questions on difference between different virtualization options. So, I thought, I will do a series of posts on explaining different virtualization technologies and their benefits. To start with, here is a quick comparison of these various virtualization types.
Recently, someone requested for a script to detect a VM’s heart beat loss and then perform a hard reset. With the experience from HVS2008 UI at hand, it was quite a simple task.
In this post I will write about my thoughts on how I wish or perceive the OS virtualization technology to be in future. Over here, I will talk about how the hypervisor layer might look like in the future and as a result, how a few more things around the hypervisor will change. I will also talk about a few benefits of this new evolution. All the information in this post is looking at the future and probably how I envision this technology. There may be companies or people already working along the same lines. I DO NOT have knowledge of any such “confidential” information. If I were, I will not discuss that here. The Hypervisor If you look at the evolution of virtualization there were multiple phases in it. It all started with mainframes and moved on to hosted virtualization or type-2 hypervisor products like Virtual PC, etc. Next biggest leap in this technology area was the development of type-1 hypervisors or bare metal hypervisors such as Microsoft Hyper-v or VMWare ESX. Today, we …
I am a bit late to write about SCVMM 2008 R2 beta because I usually don’t experiment a lot with System Center family. However, this time I registered to be a beta user of SCVMM. First impression: I am amazed. MS did some great work with the beta itself. I never used SCVMM before and I think it is a great product. I like the PowerShell cmdlets that get installed with SCVMM. They ease the management of virtual machines and host systems. So, I am experiment with this quite a bit at home and would like to post a few custom scripts I write. If you have not got your hands on this new release, here is a chance to do it. https://connect.microsoft.com/directory/ Complete the survey and become a beta user. Watch this space..!
