Building a vSphere 5 lab

Reading Time: 3 minutesFor people that need to make practice for the VCAP-DCA exam (and the beta of VCAP5-DCA will start soon) a good lab environment is mandatory. But it could also be useful for other reasons, like demo environment. There are several options to build one, but most used solutions are using nested hosts on one physical system with: VMware Workstation/Fusion over a host OS: common for a notebook. ESXi 5 on a server or a whitebox: common if you plan to have a always-on or fixed solution. Actually both solution could be good, but Workstation could […]

Convert virtual disk format – VHD to VMDK

Reading Time: < 1 minuteAs you probably already know a VM is incapsulated with a set of files that define VM properties and objects. Some of those files are the virtual disks files and each vendor use its own format: VMware use the VMDK and Microsoft & Citrix use the VHD format. Note that there could be more sub-types (for example for the VMDK files, but we will explain in future posts). To convert between different format you can use some kind of converter to perform a virtual to virtual (V2V) task.

Destinations Hard disk This the common solution, but mean the needs of a blank partition, or space to build a new partition, or the possibility to erase your disk.

Physical installation permit to test most of the features and can give better performance (for example you cannot realize how fast is the boot procedure in […]

Reading Time: 2 minutesAs written in the previous posts, in the ESXi installation there are two copy of the system image located in two different partitions (see Partitions layout of system disk and More on partitions posts). The actual system image is located on the first 250 MB partition, formatted with plain old FAT16 filesystem, but using a special pseudo-filesystem on it (see VisorFS: A Special-purpose File System for Efficient Handling of System Images). The image itself, s.v00, is a 124 MB compressed file, which is decompressed on boot and contains the hypervisor operating system. Note that the […]

Partitions are formatted with a FAT16 filesystem, but the ESXi files are stored into the banks partitions with a specific system that consist in some compressed archives containing the required files or more archives (as also described in the yesterday’s post about the reset of the root password). More details on the filesystem used is on the first number of the VMware Technical Journal, in the paper: VisorFS: A Special-purpose File System for Efficient […]
