Hyper-V over SMB – Sample Configurations

This post describes a few different Hyper-V over SMB sample configurations with increasing levels of availability. Not all configurations are recommended for production deployment, since some do not provide continuous availability. The goal of the post is to show how one can add redundancy, Storage Spaces and Failover Clustering in different ways to provide additional fault tolerance to the configuration.   1 – All Standalone     --> please see the rest on Jose's Blog...

Test Hyper-V over SMB configuration with Windows Server 2012 - Step-by-step Installation using PowerShell

In this post, I am sharing all the steps I used to create a Windows Server 2012 File Server test environment that I used for some of my Hyper-V over SMB demonstrations. My goal with this post is to share some of configuration details and the exact PowerShell scripts I used to configure the environment (if you look carefully, you might be able to spot a few PowerShell tricks and tips). For me, this is a convenient reference post that I will likely use myself to cut/paste from when configuring my demo systems in the future. This uses 5... [Lire la suite]

VM Start-up script

ack in Jan 2010 I wrote a script which shut down the virtual infrastructure, this was used to ensure your VMs were shut down and then your hosts were shut down in an orderly manner, ideal for things like UPS shutdown scripts etc. A slight spin on that is a Start-Up script, I was asked by a couple of people if I had one of these, it also becomes more relevant with the vCenter Virtual appliance, no need for HA and DRS rules or to manually search for the vCenter Virtual Appliance if there is a power outage. The script below will... [Lire la suite]

VM Backup – Backing up Virtual Machines with Windows Server 2008 R2 & Hyper-V

Virtual machines are basically made of files. They contain configuration files, virtual hard disks, snapshot files and saved state files. While running computers are virtual machines can benefit from virtualization, a lot of thought needs to be taken in order to protect the contents of the virtual machines and the VMs themselves, so that if something goes wrong, you can perform a pre-defined list of steps to successfully restore the VMs to a functional and running state We will cover the fundamentals of VM backup in a future article....

VM Network Connectivity Dropped under high load

A while ago I posted about a hotfix that would correct a problem where virtual machine network connectivity would be dropped under heavy network load (original blog post here).

We have released a new hotfix to address this problem on systems running Windows Server 2008 R2 Service Pack 1. You can download it from here: http://support.microsoft.com/kb/2263829 Cheers, Ben ...

Philippe Rondel (Check Point): «Il faut se brancher au plus près de la machine virtuelle pour la protéger»

Check Point s'appuie sur les API de VMware pour sécuriser les machines virtuelles au cœur même de la plate-forme de virtualisation. A l’occasion du VMworld 2010 fin août, Check Point présentait sa nouvelle solution de sécurisation des machines virtuelles (VM). Security Gateway Virtual Edition (VE) permet le contrôle des accès réseaux directement au niveau de la VM et non plus de la machine physique. « Avec la virtualisation, rappelle Philippe Rondel, directeur technique de Check Point France, il n’y a plus de notion de zones...

Release: SolarWinds VM Console 1.0

Last week the network monitoring and management company SolarWinds announced its second free tool for VMware administrators: VM Console. The first one, VM Monitor, monitors ESX hosts health, providing statistics about the virtual machines state (vCPUs, vRAM, vNICs) and best practices thresholds to recognize performance degradation. This new product instead allows administrators to view, search for, take a snapshot, shutdown and restart the VMs without any interaction with vCenter. SolarWinds published a video to demonstrate...
