Choosing and Installing Guest Operating Systems

119

It fails to boot because the virtual disk geometry is not probed correctly by FreeBSD

when you install the guest operating system. FreeBSD installs the boot loader in the

wrong location on the virtual disk. When FreeBSD tries to boot, the FreeBSD boot

loader asks the BIOS for important data that is now on a different section of the virtual

disk, so FreeBSD cannot boot.

This problem has been fixed in FreeBSD 4.4. This and later versions correctly boot SCSI

virtual disks of any size.

To use FreeBSD 4.0, 4.1, 4.2 or 4.3 in your virtual machine, you can do one of two

things:

• Use an IDE virtual disk in your virtual machine. You may need to add the IDE

virtual disk to the virtual machine with the Configuration Editor.

• Set the disk geometry by hand when installing FreeBSD. These steps are outlined

below.

To set the disk geometry manually, take these steps.

1. FreeBSD calculates an incorrect disk geometry before you arrive at the FDISK

Partition Editor, as illustrated here.
