How to Resize Linux VM Disks and Prepare Your Linux VM Templates

November 13th, 2017 2 comments

One of great benefits o using virtual machines is that we can increase the disk sizes whenever needed with a few clicks. In the VMware case, you can open the vSphere Client or the Web Client, and locate the virtual machine. Make sure you don’t have any snapshots otherwise you will not be able to change the disk size. Open the “Edit Setting” and select a disk you want to expand. From there, you can set a new size. There are plenty of coverage on this from VMware and other bloggers.

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.

Zimbra Architecture Overview – A Must Read Document

April 23rd, 2010 2 comments

It’s been a while after VMware acquired Zimbra. In a VMware Console blog, VMware CTO Steve Herrod explained how Zimbra fits in VMware’s mission to simplify IT.

After the acquisition, I actually tried the online demo at Zimbra website. The impression I had was that the Zimbra client was very much like Microsoft Outlook in a browser.

3 Easy Ways Connecting to Your VM in Private Cloud

February 24th, 2010 30 comments

Several folks asked me about how to use vSphere(VI) Java API to connect to a VM running on vSphere. The quick answer is vSphere Java API is not designed for this. You will need VMware Remote Console, browser plug-in, remote desktop/VNC, SSH client etc. However, it can help you to get the information required by the console or plug-in. Tal Altman from CISCO suggested that it be a topic for doublecloud.org. Here it is.

There are 3 ways to connect to the VM from your client side outside the vSphere and Web Access which have built-in support for console access.

  1. Using VMware Remote Console which is a standalone application
  2. Using browser plug-in to either IE or Firefox (Note: this is NOT supported by VMware. Please don’t call the company tech support for this.)
  3. Using Remote Desktop, VNC or SSH

The first two connect to the ESX host, and work even there is no guest OS installed on the VM. The last one assumes you have guest OS installed, and have IP network and server components in place already.

Note that these 3 ways work for the VMs in the public cloud as well if the related ports are open in your firewall. It is, however, not the case for most enterprises, therefore I particularly say it’s for VMs in private cloud. If you don’t have firewall issue, feel free to give it a try with public cloud as well.

Let’s go over one by one in details and see how vSphere Java API helps.
