caching

Scenario: SQL Server 2005 or 2008, Windows 2008 OS. Running in a VM hosted on VMWare ESX server.

Is there any known issue with VMWare when it caches pass-through write request and it never reaches the disk, while SQL Server "thinks" that write actually happened? This may lead to transaction log corruption in case of power failure or VM reboot. Just overheard the conversation but couldn't find it in relation to ESX.
