VM Deployer 1.5 Released: VM Power Management, Deletion, and Regular Expression

August 8th, 2017 2 comments

Since the first release of VMDeployer, we’ve seen so many downloads that we decided to invest more time even though it’s a free tool. The community support can be bigger motivation than anything else.

Here we have this 1.5 release which adds a few more features. Most of these features are there for users to have complete end-to-end user experiences. I will explain why under each item.

vmkping: Tricks You May Not Know for ESXi Jumbo Frame Troubleshooting

August 8th, 2017 2 comments

The vmkping is a built-in tool for troubleshooting connectivity in ESXi. It’s very similar to the normal ping command. The typical usage is as simple as: ping or ping . Several command arguments make it pretty powerful and you will find it an indispensible tool in troubleshooting ESX networking issues.

Before getting started, you want to find an ESXi server with SSH service open. If the ESXi is in lock down mode, you can easily unlock it from vSphere Web Client. When you can ssh to the ESXi server, you are ready to move forward.

Troubleshooting Open VMware Tools

August 2nd, 2017 2 comments

As I wrote in a previous article, installing open vmware tools can be as simple as one command on Linux. It worked for us all the time. Exceptions do happen sometimes. I recently helped a troubleshooting case in which the open vmware tools failed to start. Here are some of the troubleshooting steps and solution that you can apply if you will get into such cases.

VMDeployer 1.4 Released: Light Weight GUI to Deploy and Backup Your VMs

August 1st, 2017 2 comments

When version 1.2 was released, I had almost finished the work on 1.3. Then, I got a few interesting ideas and quickly implemented them altogether. Instead of releasing 1.3, I’d pull things together for 1.4 release.

Here are a few highlights in this version 1.4:

Install VMware Tools on CentOS 7 – The Easy and Quick Way

July 18th, 2017 3 comments

It’s seemingly easy to install VMware Tools especially on Linux. In reality, it can take hours to get it installed correctly for the first time. The KB article on VMware site is unnecessarily complicated, and could be a source of confusion.

Here is one line to get your Open VMware Tools installed on CentOS 7.

# yum install -y open-vm-tools

Once it’s installed, you should able to see the file:

Free Tiny GUI Tool to Deploy OVA or OVF to All Versions of VMware vSphere: VMDeployer 1.1 Released

June 30th, 2017 2 comments

With the release of version 1.0 of our free GUI tool to deploy virtual machines on all platforms, we’ve successfully solved the issue of deploying our search appliance using the vSphere Web Client. We have a few more happy new customers ever since.

However, it could not deploy the NSX manager because 1.0 does not support OVF properties. To be exact, the deployment goes through, but the deployed NSX Manager VM cannot power on due to the required OVF value is not set for the admin password.

Announcing vijavaNG 6.5.1 Beta with Tagging and VCSA Management APIs

May 16th, 2017 2 comments

With the increasingly wider adoption of commercial vijavaNG in the VMware communities, we always seek to enhance and extend the APIs beyond these like ESX agent APIs. Today we are happy to announce the 6.5.1 which support for the tagging and vCenter appliance management APIs.

Free Java GUI to Deploy VMs onto vSphere of All Versions – A Solid and Fast Alternative to vSphere Web Client and ovftool

May 8th, 2017 1 comment

Recently we got quite a few complaints about installing vSearch appliance OVA onto vSphere 6.5 using the vSphere Web Client. It does not work. As a quick workaround, we told customers to try the VMware ovftool command line. While it works mostly, we still got questions and issues on the usage. For one thing, it’s not always straight-forward and easy to get the parameters right.

Alpine Linux on vSphere: Is it Really Small in Size?

April 11th, 2017 1 comment

I came to know the Alpine Linux because of its small image size for Docker. Unlike almost 200MB in size of popular CentOS and Ubuntu, it just needs 5MB. That made me wonder if I can get much smaller Linux VM using the Alpine distro for special use cases like network tools.

Deploying OVA onto VMware vSphere: Issues and Workarounds

March 31st, 2017 1 comment

Update: this issues are fixed with the VM Deployer tool we just release as described here.

With the increasing adoption of VMware WebClient, we got more support cases from customers who use it for deploying our search engine appliance. In one sentence, it does NOT work and you will get error messages like, “the provided manifest file is invalid OVF.”

No More Spread Sheet or Wiki Page: Better Way to Track IP Addresses

January 19th, 2017 4 comments

IP addresses are important resources and must be carefully managed to avoid duplicated IP issues, which are sometimes very hard to troubleshoot. I still remember that it took a few of us couple of days to root cause a failing new feature, which worked sometimes and did not other times. Because it’s a new feature, we mostly thought it was somehow our bug in code. It turned out not, but caused by the vCenter we were testing actually used a duplicated IP address.

Announcing vijavaNG 6.5 – the smallest, fastest, and most secure Java APIs for VMware vSphere 6.5

November 28th, 2016 4 comments

On November 15, VMware offically announced the long-waited vSphere 6.5, which is a big release after 6.0 release early last year. Along with this vSphere release were a few other products like VMware vSAN 6.5, VMware vRealize Log Insight 4 and VMware vRealize Operations 6.4. According to the blog announcement, the vSphere 6.5 offers these high level features and benefits:

Slow Exporting OVF/OVA from vSphere Client or ovftool? A Quick Tip Can Save You Hours

November 8th, 2016 5 comments

Over the weekend, I was trying to export a virtual machine from vSphere using ovftool command line. To my surprise, it was extremely slow. In fact, I wasn’t patient enough to wait for its finish and “Contrl+C” it. Initially I was thinking it could be ovftool issue, so I tried exporting from vSphere Client directly. Still very slow and I had to cancel it as it would run for a few hours according to the progress dialog box.

Too Early to Say GoodBye VMware vSphere Client?

May 22nd, 2016 4 comments

VMware published a blog “Goodbye vSphere Client for Windows (C#) – Hello HTML5” with two announcements: 1. There won’t be the traditional C# based vSphere Client for the next version of vSphere (no one knows the version yet but it’s safe to call it the next version.). 2. The vSphere HTML5 Web Client Fling will be supported soon (no exact timetable is given). My guess is that it will make into next release of vSphere if not earlier.

Paradigm Shift in Data Center Management: What’s After VMware?

March 10th, 2016 No comments

The recent release of DoubleCloud vSearch represents a paradigm shift in how we manage data center in the future. Before agreeing with me on that, let’s take a quick look at the history.

Yahoo vs. Google

When the Web first came out in the early 90s, there weren’t many Web sites and pages out there. To help us find pages of interest, a typical directory approach was used. That created the initial success for Yahoo in the first place.

DoubleCloud Inc Announces “Super vCenter” with Unlimited Scalability

February 2nd, 2016 2 comments

After leaving VMware and VCE, I founded DoubleCloud Inc. While working with many of my clients, we found it’s really a pain point for people to use vSphere Web Client which is quite slow and based on obsolete Flash technology. The old vSphere Client is a lot better in performance and usability, but VMware stopped upgrading it with new features.

How to Build Smaller and Faster Virtual Appliance

September 28th, 2015 No comments

While building a new server product of its own kind, we chose virtual appliance as the package. During the development phase, we configured thin disk to save space. But for our beta customers to try out, we decided to switch to thick disk for better performance as the product has to do lots of processing and heavy disk I/O. BTW, we still have a few slots for new beta customers with have large vSphere deployments. Please contact me if you are interested.
