Virtualizing Mac OS X Leopard Client

VMWare Fusion 2.0 beta2 supports virtualizing Mac OS X Server as a guest OS. If you try to install a Leopard Client guest, you get an error

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

<?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 &amp; wait $!</string>
    </array>
    <key>KeepAlive</key>
    <true/>
    <key>RunAtLoad</key>
    <true/>
</dict>
</plist>

Then run

sudo launchctl load /Library/LaunchDaemons/com.rectalogic.vmware.plist

Now 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.

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 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.

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.

Elevator Pitch

I was riding down to lunch in a relatively crowded elevator at work and two guys were in opposite corners carrying on a conversation about work over everyones heads. Then, this happened:

Guy #1:

You want go go out tomorrow night?

Guy #2:

Sure, I told you I'm single again right?

Guy #1, as if embarrassed by this personal detail in a public elevator:

Uhm, let's talk about this over lunch.

and then Guy #1 continues:

By the way, I'm probably going to go for a 'rub and tug' after lunch, this Asian girl I go to is really into fiddling with my asshole.

Absolutely beautiful.
