Gee, very interesting "bug" in VMWare. <quote> Irate VMware customers were left unable to power up their virtual servers this morning because of a bug that killed their systems when the clock clicked round to 12 August.
The bug was sent out to customers in ESX 3.5 update 2, VMware's latest hypervisor, which went out on 27 July. The version could have been downloaded and installed by thousands of customers since then. </quote> http://www.theregister.co.uk/2008/08/12/vmware_12_august_esx_cockup/
