When converting from VBox, it uses an ATA disk, instead of VMWare's default of SCSI guest disks. This means FreeBSD enables the ATA write cache by default, which VMware honors and might be prone to lose data on power outage. I suspect you should either set hw.ata.wc=0 in loader.conf, or switch to SCSI gues disk type. But its still possible there was CPU/RAM problems and you were just lucky that the other guest disks didnt get corrupt as they may not have been writing to directory metadata at the time of crash. - Andrew
