Photon OS installs by default with DHCP enabled. This is perfect for building and distributing Photon OS OS as a Virtual Appliance, but for most practical applications, you’ll want to set a static IP address. Changing the IP of Photon OS involves a newer, albeit standardized procedure of editing files located in: /etc/systemd/network that will… Continue reading “Setting static IP for Photon OS”
For some users, whether you should or shouldn’t use SSH is a matter for debate. Rather than be hypocritical, I simply acknowledge that most admins will access Linux systems using SSH, and prefer to suggest that using strong passwords or passphrases and secure Management Networks is a more realistic approach to Linux administration.
VMware photon OS is described as “yum compatible.” Yum has been the package manager for all Fedora derivative distros like RHEL and CentOS. Photon OS actually uses Tiny DNF (TDNF), which appears to be a fork of the Fedora DNF package management system.
When I first started using VMware products, ESX Server ran on Red Hat, Virtual Center (vCenter) ran on Windows, there was no such thing as a “Virtual Appliance,” or at least the term had not yet been coined and Photon OS was a long way in the future!
VMware Workstation Pro 14 is a 64-bit Type 2 Hypervisor that is available for Linux and Windows. As a Type 2 Hypervisor, Workstation Pro runs as an application on top of a full Operating System like Windows 10 or Ubuntu Desktop and claims compute and hardware resources from the parent OS, then allocates those resources… Continue reading “Installing VMware Workstation Pro 14”
Being successful with VMware vSphere is largely about understanding “Who’s on first, What’s on second and Idunno’s on third,” at any given point in time. This is especially true with the VMware vCenter Server Appliance (VCSA), as it presents a several new console choices to the administrator.
I recently went looking for information on password security for the VCSA 6.0 & 6.5 and ESXi 6.0 & 6.5. Most specifically, I was interest in the number of passwords remembered, so I could define that in documentation for a client. Try as I might, I couldn’t find documentation for VCSA number of passwords remembered… Continue reading “VCSA and ESXi password security”
I’ve recently spoken with a number of VMware vCenter Server Appliance 6 (VCSA) users that have had issues with the root filesystem of VCSA running out of space. This situation seems to be occurring more often now due to a combination of when the VCSA 6 went mainstream (18 to 24 months ago) and the… Continue reading “VCSA disks become full over time”
The Open Virtual machine Format (OVF) originally came about in 2007 as the result of a proposal by vendors (VMware, HP, Dell and others) to the Distributed Management Task Force (DTMF), the goal being to create an open standard for interchangeability (portability) of Virtual Machines between hypervisors. VMware was an early and enthusiastic adopter of… Continue reading “OVF and OVA formatted Virtual Appliances”
In the following steps, I am going to show you how to set all of the VMFS Volumes (LUNs) on an ESXi Host to use the PSP known as Round Robin, using only the ESXi Shell and/or SSH. This is clearly the simplest and most direct method of changing the PSP for existing volumes, and… Continue reading “Changing existing LUNs to Round Robin on ESXi”
