If an Ubuntu server is configured to use the floppy disk module and a floppy disk does not exist on the server (which none of the VMs have actual floppy disks), the OS will send error messages to the vmware console.
The messages will look something like this:

The floppy disk module will need to be removed to get of these error messages.
First, verify that the floppy disk module is loaded (it obviously is, but just to make sure). Below is the command and similar output (the numbers may be different):
> lsmod | grep floppy
floppy 16384 0
To remove the floppy module, issue the following commands, followed by a reboot:
> sudo rmmod floppy
> echo "blacklist floppy" | sudo tee /etc/modprobe.d/blacklist-floppy.conf
> sudo dpkg-reconfigure initramfs-tools
> sudo /sbin/reboot now
After the reboot, make sure that the floppy module is not longer loading:
> lsmod | grep floppy
>
