La procédure est très simple … mais très mal expliquée sur le site de Vmware !

Il faut tout d’abord se connecter en SSH sur le host ESXi à upgrader.

La première opération consiste à autoriser le traffic sortant au niveau du firewall

esxcli network firewall ruleset set -e true -r httpClient

Il faut ensuite obtenir la liste des images disponibles

esxcli software sources profile list -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml

Je n’ai toujours pas compris l’ordre de tri et j’applique donc un filtre pour trouver la dernière version :

esxcli software sources profile list -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml | grep ESXi-5.5 | grep 2014

A l’heure où j’écris ces lignes, la dernière version est ESXi-5.5.0-20140902001-standard

Je n’ai plus qu’à mettre à jour mon host avec cette version ce qui se fait avec la commande :

update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-5.5.0-20140902001-standard

Voici le résultat :

Il ne me reste ensuite plus qu’à déplacer mes machines virtuelles sur un autre host (ou les arrêter dans le cas d’un host unique) et rebooter le host sur cette nouvelle version
