Reading Time: 3 minutesVMware, Inc. today unveiled VMware View™ 5.1 and an updated portfolio of end-user computing solutions designed to empower a more agile, productive and connected enterprise (the product is expected to be available in Q2 2012 ). There are several interesting news in this new release, and actually seems that not all are yet listed (maybe some feature in the beta will be not released yet). But more interesting is the new set of products designed to be used with View: VMware vCenter™ Operations for VMware View: Cloud Infrastructure Insight – To be offered as a […]

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 […]
Reading Time: 2 minutesIn a previous post I’ve described the partitions used by a ESXi installation (see ESXi – Partitions layout of system disk). 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 […]
Reading Time: 2 minutesReset the root password with ESX 3.x was quite simple, just because the service console was a partition writable a live CD… With ESX 4.x it was a little more complicated (the service console was basically a vmdk). But with ESXi things are more complicated, due to the partition layout, that ESXi works in RAM and that all configurations files are stored in the banks it special archive files. The file containing the password hashes is called “shadow” and it is is contained in a nested structure of archives inside the state.tgz file.
Reading Time: 4 minutesAs written in the previous post, there are two vNIC in the VLM appliance, because there are two different scenarios of network topologies (well described in the LoadMaster Installation & Configuration Guide at pages 12-13): one-armed (similar to a bastion host firewall configuration) or two-armed (similar to a firewall dual-homed). Looking at those configurations, and comparing with Linux Virtual Server, seems that the forward methods (Direct Server Return and NAT) are bounded with the network topology. But for VLM there is no correlation and you can use the preferred forward methods (although DRS remain the […]
Reading Time: 2 minutesAs written, VMware has release a week ago the new version of VMware View 5.0.1 (with the new build 640055), as also the new version of vSphere 5.0U1. Note that the VMware Composer remain the same 2.7.0 (build 481620) of previous version. As report in the VMware View 5.0 Installation Guide (page 10), the VMware Composer is compatible with vSphere 5.0 and later, so it is just a piece that will not need any upgrade. Actually the View documentation is not changes to reflect the new version, it remain a simple 5.0 version. So the […]
Reading Time: 2 minutesLast week VMware release a complete update of the entire cloud platform, including the new vSphere 5.0 Update 1. But, compared with the 5.0 version, the new vCenter Server 5.0 U1 has a new feature (of bug, depending of the point of view) that now disable the VM Startup & Shutdown properties for all the host (also old version) in a VMware cluster:
