My colleague (thanks Kevin), just alerted me to a default setting on ESX 4, which I think is potentially dangerous these days.  If you hit Ctrl-Alt-Del on an ESX 4 console, it will reboot the server even if there are running VMs and it doesn’t care if the server is not in Maintenance Mode. This is an old throwback which most modern Linux distribution disable these days.  To disable this yourself, open up /etc/inittab in your favourite editor and comment out the “ca::ctrlaltdel:/sbin/shutdown -t3 -r now” line with a #...

Install ESXi 4.0 to an IDE drive

retour-de-mon-ami-julien-propos-de-view

Mon ami Julien, créateur du site forum-vmware.fr devenu vmug.fr, a donné ses premières impressions concernant VMware View 4 à (mon autre amie) Kareen Frascaria sur Virtuanews. J'appuierai volontiers le dernier point en exprimant le fait qu'il faut bien valider les aspects bande passante notamment sur le WAN. Les boitiers d'optimisation façon WAAS seront vraisemblablement bienvenus.A noter que les terminaux Wyse embarquant Windows CE et Linux supporteront dans un premier temps le protocole PCoIP.

Partitioning your ESX host – part II

Voici ce qui nous préconise Duncan pour partitionner ESX 4 (vSphere) : A while back I published an article on partitioning your ESX host. This was based on 3.5, and of course with vSphere this has slightly changed. Let me start by quoting a section from the install and configure guide.You cannot define the sizes of the /boot, vmkcore, and /vmfs partitions when you use the graphical or text installation modes. You can define these partition sizes when you do a scripted installation. The ESX boot disk requires 1.25GB of free... [Lire la suite]

Processor requirements can be more if your database runs on the same hardware. 2 GB RAM. You might need more RAM if your database runs on the same hardware.
