I wrote this script to create VMs, since we're making 350 for the remote access project. It used some code that a co-worked found on the internet, but I modified it appropriately so it would loop and create more than one.

#!/bin/bash
declare -i hexcount=0x0
for vmcount in $(seq 1 5)
do
VMDIR=vdi$vmcount
VMNAME=vdi$vmcount
VMMAC=00:50:56:00:01:$(printf %02x $hexcount)
NFSVOL="cgy-vdi-nfs01"

#Begin pasted script code
#Creates a new Virtual Machine

VMOS="winxppro"
VMDSIZE="20g"
VMMEMSIZE="1024"

mkdir /vmfs/volumes/$NFSVOL/$VMDIR
exec 6>&1
exec 1>/vmfs/volumes/NFSVOL/$VMDIR/$VMNAME.vmx

# write the configuration
echo #!/usr/bin/vmware
echo config.version = '"'8'"'
echo virtualHW.version = '"'4'"'
echo memsize = '"'$VMMEMSIZE'"'
echo floppy0.present = '"'TRUE'"'

echo floppy0.fileName = '"'/dev/fd0'"'

echo

exec 1>&6
