The guest operating system is not Mac OS X Server.However, if you create an ISO/CDR image from your Leopard install DVD, mount it then do
touch "/Volumes/Mac OS X Install DVD/System/Library/CoreServices/ServerVersion.plist"then unmount it, you can now use that image to install Leopard Client into VMWare with no complaints. After you install, reboot VMWare from the install DVD ISO again, run Terminal and
touch "/Volumes/Macintosh HD/System/Library/CoreServices/ServerVersion.plist"then reboot from the HD. This probably violates your license agreement so don't do it, I certainly wouldn't.
Update: You can automate the deletion and creation of the ServerVersion.plist file using a LaunchDaemon. Put the following xml in a new file /Library/LaunchDaemons/com.rectalogic.vmware.plist
Then run<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.rectalogic.vmware</string> <key>ProgramArguments</key> <array> <string>/bin/bash</string> <string>-c</string> <string>/bin/rm -f /System/Library/CoreServices/ServerVersion.plist; trap "/usr/bin/touch /System/Library/CoreServices/ServerVersion.plist; exit" SIGINT SIGTERM SIGHUP; sleep 999999 & wait $!</string> </array> <key>KeepAlive</key> <true/> <key>RunAtLoad</key> <true/> </dict> </plist>
sudo launchctl load /Library/LaunchDaemons/com.rectalogic.vmware.plistNow when you login ServerVersion.plist will be deleted, when you shutdown it will be recreated ready for the next reboot.
Alternative approach: An alternative approach discussed in the comments is to hack VMWare to disable the check for server.
VMWare Fusion 3.0: Fusion 3.0 uses EFI instead of BIOS by default. After creating a new VM and before booting it from the install DVD/ISO, edit the *.vmx file and remove/comment out the firmware="efi" line. VMWare will then use the hacked boot image from darwin.iso.sudo bash cd "/Library/Application Support/VMware Fusion/isoimages" mkdir original mv darwin.iso tools-key.pub *.sig original perl -n -p -e 's/ServerVersion.plist/SystemVersion.plist/g' > darwin.iso openssl genrsa -out tools-priv.pem 2048 openssl rsa -in tools-priv.pem -pubout -out tools-key.pub openssl dgst -sha1 -sign tools-priv.pem > darwin.iso.sig for A in *.iso ; do openssl dgst -sha1 -sign tools-priv.pem < $A > $A.sig ; done exit
VMWare Fusion 4.0: Fusion 4.0 is similar to 3.0, but the path in the script above must be changed from /Library/Application Support/VMware Fusion/isoimages to /Applications/VMware Fusion.app/Contents/Library/isoimages. Each time you boot the guest you will get an error dialog No operating system was found. Click OK. You may then get an error dialog Your Mac OS guest is using this CD-ROM device. Click Cancel. Now you should have a black screen with No operating system found displayed, click on the window and hit Return to boot.
