Use "genisoimage -J -o" to create ISOs for use in VMs

The easiest way I found to get files onto a Windows XP VM without installing any drivers is to put the files into an ISO and load that into the virtual CDROM drive. You can use the genisoimage tool on Linux to create these ISOs:

genisoimage -J -o files.iso some-dir-of-files

Note: the -J flag is used to create Windows-compatible long/Unicode file names. If omitted, the ISO should work on DOS, but filenames will be in uppercase 8.3 format.
