VMware ESX/ESXi
Publish VMware vSphere client with TMG 2010
0There are situations in small environments when you need to access your ESX/ESXi server from the internet, for troubleshooting or just to create or restart a virtual machine. I bet that’s a piece of cake for some of you, but what if you have a TMG server as a firewall. Well…things are not so easy any more, but they are not complicated either. If you have a situation like this, where a TMG 2010 server acts as a firewall for you or for some of your clients, and want to access an ESX/ESXi server from the internet, then you came to the right place.

Replacing VMware ESX server default (self signed) certificate
0I bet you got tired of those annoying certificate messages every time you connect to your ESX/ESXi servers. And is not just about the messages, is more about trusting the host, you or your users connect to. There are situations when you need to have a proper and a trusted certificate on you ESX/ESXi hosts, and in this guide I’m going to show you how to replace the default (self signed) certificate with a proper one.

In-place upgrade from VMware ESX 4.1 to ESXi 5
0For those small businesses that don’t afford buying VMware vCenter and want to upgrade from ESX 4.1 to ESXi 5, an in-place upgrade is the only way to go. In this guide I’m going to show you the steps involved in the upgrade process. For this lab I have an ESX 4.1 server with some virtual machines located on the local datastore, so no iSCSI or Fiber Channel Storage is connected to the server. Even if they were connected the process will be the same. (more…)
Creating virtual machines in VMware vCenter 5
0Creating virtual machines was an easy job in previous versions of vCenter, and it’s still is, just a couple of options changed during the wizard. In this post I’ll show you how to create a new virtual machine on a ESXi 5 host using vCenter 5. (more…)
Install VMware (vSphere) ESXi 5 in VMware Workstation 8
0I think you already installed VMware Workstation 8 on your PC, as a result of the new features. Version 8 has native support for VMware ESXi 5 meaning, you can run ESXi servers inside VMware Workstation without hacking the .vmx file. The good news, is you can create and run 64bit VMs inside that virtualized ESXi server which runs in VMware Workstation. You should never run this in a production environment, is just for “fun”. To be able to do this your host processor needs to support Virtualization Technology. I run this lab on a Intel i7 930 processor, so is green light for me. (more…)
How to create a VMware Cluster
0To be able to create a VMware cluster you need vCenter, and at least two ESX Servers. For this guide I’m going to use ESXi 5 and vCenter 5. ESXi hosts are already added to vCenter. I’m not going to discuss about cluster features like HA (High Availability) and DRS (Distributed Resource Scheduling), I will talk about them in future posts. (more…)
Configure Active Directory integration for VMware vSphere and ESXi
0We all know AD (Active Directory) is to centralize things, but for Windows machines. Well… starting from version 4.1, VMware is offering the option to integrate their ESX/ESXi servers with Windows domains. Yes, you could integrate older ESX/ESXi versions with Windows domains, but it was a paint, you had to use scrips and hacks. Now starting with VMware vSphere 4.1, the integration is done using a couple of mouse clicks in vCenter. You still have the option of scripting this process using PowerCLI, if a big number of hosts exists in your environment, but in this post I will show you how to do it using VMware vCenter. (more…)
Licensing ESX, ESXi and vCenter Server
0You downloaded an evaluation copy of ESX/ESXi and vCenter, but that evaluation has come to an end. The second part is, that you really like these products, because of the benefits and costs reductions they bring, so you decided to buy a license. The last step is to license the software, and this guide is going to show you how. For this demonstration I have four ESXi 5 serves already added to a vCenter Server 5, so let’s get started. (more…)
How to add ESX/ESXi hosts to VMware vCenter
0I can tell you from the start that this is an easy job. With just a few clicks you are going to add your first ESX/ESXi host to your vCenter Server for better management and monitoring.
Before we start is very important that your DNS is configured correctly. In my lab here I manually created the DNS A record for the ESXi host. If you don’t create this DNS entry you will have to use the IP address of the ESX/ESXi server, when running the vCenter wizard for adding a host. I am also running VMware ESXi 5 with vCenter 5. (more…)
Install VMware ESXi 5
0For those of you that don’t know what ESXi is, I will tell you briefly. It’s a virtualization product or hypervisor, that let’s you run multiple OSs at the same time using a single physical server. Hypervisor means it works directly with the hardware, it doesn’t need an operating system, ESXi itself is an operating system. The biggest competitor is Microsoft hypervisor called Hyper-V. To be able to install 64 bit systems on ESXi you hardware must support Virtualization technology. You can find more information about VMware ESXi5 here; and because I don’t want to bore you reading too many lines of text, I will start working. (more…)
