VMware ESX3.5 datum bug

13 August 2008

Door een datum bug in VMware ESX 3.5 en ESX 3.5i willen VM's niet meer op starten.
Door de bug denkt het systeem dat de licenties per 12-augustus zijn verlopen, dit ten onrechte.
VM's die actief zijn blijven gewoon doordraaien.

De bug zit in de VMware ESX 3.5 Update 2 (build number 103908) en ESXi 3.5 Update 2 (build number 103909), deze versies zijn inmiddels door VMware off-line gehaald. 


De volgende error wordt in de vmware.log geschreven van de VM.

This product has expired. Be sure that your host machine's date and time are set correctly.
There is a more recent version available at the VMware web site.

Module License Power on failed.
