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: 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: 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 […]
