Reading Time: 3 minutesIf you want to “play” with Windows 8 Consumer Preview or “Windows Server 8” Beta, then there are several installation options. 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. If you choose a dual boot configuration, of course, the bootloader must be modified to add the new entry. 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 […]
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: 3 minutesAs most people know, Intel adopt a Tick Tock model for processors development: a tick advances manufacturing technology, a tock delivers new microarchitecture. Usually this mean that a tick means processors with more frequency speed (sometimes also more cores and/or more cache) and a tock means usually new features (but not necessary more frequency speed and/or more cache/cores). But when a new generation (tick or tock) as been introduced, after some months, this usually means cheaper processors (or at similar price) compared to previous generation. Now a possible confusion could be generated by the Westmere […]
Reading Time: 2 minutesMicrosoft has recently made some changed in certifications and also has introduced new paths, like the new MCSE: Private Cloud certification. The path has the following requirements: become a MCSA: Windows Server 2008 pass the Exam 247: Configuring and Deploying a Private Cloud with System Center 2012 (Until January 31, 2013, Exam 70-659 may be taken in place of 70-247) pass the Exam 246: Monitoring and Operating a Private Cloud with System Center 2012 Note The Private Cloud certification requires candidates to show continued ability to perform in this technology area by completing a recertification […]
Reading Time: 2 minutesAlthough the official confirmation has yet arrived via email, it seems that (also) this year I was confirmed as a vExpert. Or at least they appear on the list published on the site: Announcing vExpert 2012 title holders. Considering the changes in the vExpert program and that I’ve tried the “Evangelist” path (probably the most “wanted” or at least desired… and where there are some really great evangelists) I be enormously honored by this confirmation. It ‘s been less than a year since the last vExpert 2011, but I seems that were only few days.
