I changed the following 41 days ago: - Video memory to "auto" if it wasn't already - SCSI controller changed from LSI Logic Parallel to LSI Logic SAS It uses the same driver (da) but so far has been holding steady for us. As far as the video memory -- many of our servers somehow had video memory set to 1MB which seemed strange; newer builds of FreeBSD on ESXi do not show this option. Perhaps there was a build of ESXi in the past that had a different setting for video memory when you selected FreeBSD? Another change people might want to do as suggested to us by VMWare Support: - Change CPU/MMU Virtualization to the bottom option -- "Use Intel VTx/AMD-V for instruction set virtualization and Intel EPT / AMD RVI for MMU virtualization" Supposedly there are autodetection issues here with some OSes -- they named some BSDs and Netware. I'll provide further updates if anything changes, but this seems to be working well so far. We won't begin to trust it until we can hit at least 100 days of uptime, though. Unfortunately I was hoping to upgrade these servers to 8.3 before then...
