Good morning everyone! today we will give a talk for the community of VMware Galicia users in Santiago de Compostela; where we will compare different hypervisors and see a little about their differences or their evolutions. I wanted to share the presentation with you all, I leave you a PDF link to read and another with the presentation as such (for Windows or Mac). By the way, I share the presentation with the crack Miguel Angel Alonso of JMG!!!
ESX System Analyzer is a virtual appliance that will allow us to obtain detailed reports of our current ESX infrastructure, to see if we could migrate to a vSphere environment 4.1 or 5.0 (with ESXi hosts, Of course). These reports, presented in spreadsheets, show us a full host-level analysis, VMs and datastores,
In this post we are going to fingerprint between esxi servers 4.1 to build trust between them and not rely on a validation request. With all this we can make ssh connections between them without being stopped asking for credentials.
This upgrade process will be the most used among those of us who have VMware vSphere environments with ESX hosts 4.0 and we want to upgrade them to ESX 4.1, since we will do it in an orderly and managed way through Update Manager, This document shows the steps we will need to update our hosts to the latest version.
ghettoVCB.sh is one of the few good scripts I know that can help us make copies of our VMware environment for free, This is, we will be able to make backups on both ESX and ESXi servers without a license! We can say that it behaves the same as the traditional VCB, Takes a snapshot of the virtual machine to be copied, It copies the virtual machine's files to a directory and then deletes the snapshot. ghettoVCB is a script that must be run on the VMware ESX server itself(i), we can schedule it to run using 'Cron’ or as in my case I will run it from a remote computer using the utility plink.exe. In addition, ghettoVCB stores backups in an ESX datastore(i), In this document we will see at the end how to make the backup in a Windows folder that we have thanks to NFS.
Starting with the new version of VMware ESX 4.1 or VMware ESXi 4.1 it already supports the use of USB devices connected to our hosts and pass the redirection to virtual machines. In this document we will see how to configure it, It is very simple and can be done hot.
As we all know, one of the new features brought by VMware vSphere 4, is that the web management environment of ESX hosts is disabled by default, We assume that it will be due to performance and security issues. This document shows how to enable Web Access on our ESX servers 4.
If we intend to upgrade our VMware virtual platform, before upgrading to the VMware vSphere version we must run a utility that we have on the VMware vCenter Server CD, where we can check if our ESX hosts are compatible for a possible version upgrade (from VMware ESX 3.x to VMware ESX 4.0) thanks to VMware Agent Pre-Upgrade Check.
Ideal for when we want to install VMware ESX 4 on a server that does not have a CD-ROM drive / DVD ROM, or directly if we want to save that money by putting a CD drive on the server. The intention of the document is to show how the installation can be carried out from a USB drive being an external hard drive or even a USB Pendrive. It is quite useful on certain occasions.
One way to help us in the configuration of our virtual environment is to rely on one of the new features that VMware vSphere brings 4, the ability to use already configured templates to apply to all our ESX hosts, or for when we add a new VMware ESX host to our virtual community, we can apply the same configurations that one of our hosts already has.. We can create a template from scratch by configuring everything manually or get said template from one of our servers already configured perfectly (being able to edit the profile if necessary), and then apply it to the rest of the hosts that do not meet the requirements that we indicate. This is called the VMware Host Profile.
