When I try to install VMware ESXi 4.1 from CD onto our server at our office, it fails with the error "vmkctl.HostCtlException Unable to load module /usr/lib/vmware/vkmod/vmfs3: Failure". I get as far as accepting the license and seeing a progress bar move across the screen, but as the bar finishes, it dies.
The server is a PC with a Gigabyte P45 based (ICH10) motherboard and Intel Q9550 (45nm Core 2 Quad). The BIOS has settings to turn AHCI on and off, as well as switching ports 0-3 between native and legacy mode. I have tried all combinations, and none of them work. If I turn of AHCI, the install CD often does not boot at all, just giving me a disk error.
I was switching from VMware Server to ESXi because Server 2.0 only has a non-functioning web interface, with well documented fatal bugs. However, it's beginning to look like the better option of the two. I may have to abandon VMware.
