vSphere 5.0: Setting Up the Virtual Machine Environment
After logging into vSphere 5.0, the first thing you will see is a category screen, with options to see your inventory (your ESXi server), roles (users), and system logs. From inventory, you can select your ESXi server. After selecting the whitebox server, you are given several tabbed options, one of which is “Summary”, which gives you an overall hardware description of your ESXi server. Details such as processor model, motherboard model, CPU cores, CPU usage, memory usage, etc., are listed. With the whitebox setup that I am utilizing, what’s probably the most interesting part of this section is that ESXi 5.0 is reporting that DirectPath I/O (IOMMU) is supported (woot!) on the GA-970A-UD3, which allows us to passthrough hardware devices directly to the VMs. Not too many consumer motherboards support this feature, which makes this even more exciting.
Moving on, before you can start creating VMs, a storage space must be created. As this whitebox server has two hard drives (a Seagate Barracuda ES 1 TB 7200 RPM and WD 80 GB 7200 RPM SATA HDD), we can assign storage spaces to these devices by going to the “Configuration” tab and selecting “Storage”. Here in this section, there is an option to “Add Storage”, in which we can specify a storage device to utilize. Clicking on this option, it gives us a choice to select the type of storage, such as a local disk, iSCSI, etc. or a Network File System (NFS), but simplicity of this setup, we will be using the local drives installed on this server. In the next screen, a list of all detected hard drives will be shown, from which we can select a hard drive to create a storage space. After selecting a drive, an option to specify whether to utilize VMFS-5 or VMFS-3 will be shown. As I won’t be utilizing legacy operating systems that have issue utilizing storage spaces larger than 2TB, I selected VMFS-5. After going through the storage spaces setup prompts, your newly created storage space will show up in the “Storages” section. Please note that this must be done every time if you wish to utilize additional storage devices.
With a storage space created, we can now create virtual machines! In the “Virtual Machines” section, we can create a new VM. In the new VM wizard, we can specify if it is a typical or custom VM. The “Typical” option used for common operating systems such as Windows XP, whereas the “Custom” option is used for situations where additional options need to be specified, or in cases where a unsupported OS will be installed. From here, we can specify options such as the name of the VM, the VM OS type (i.e. Windows, Linux, Other), the storage space it will be installed to, the network type & adapter that will be utilized, and the amount of storage space assigned to the VM.
Once all of these options have been confirmed, ESXi 5.0 will take a moment to create the VM onto the storage space that you have specified. Once the VM has been created, it will appear in the “Virtual Machines” list. You can make changes to the VM’s virtualized hardware, such additional storage space, optical drives, network options, etc. I decided to install Windows Server 2008 as my first VM, as I want to experiment with some of the server roles like Active Directory, Domain Controller, Sharepoint, SQL, etc. Through the optical device options of the VM, I selected the Windows Server 2008 ISO image, from which to boot from to initialize the installation. Within the VM, I went through the typical Windows Server 2008 installation wizard, which progressed without any issues. After twenty minutes of installation, the Windows Server 2008 VM was ready to be utilized!
In the next portion, I will go over more detail in managing multiple VMs on ESXi 5.0.
