VMWare Fusion Images with a static IP Address on Mac OS X Snow Leopard

How to setup your VMWare Fusion images to use static IP addresses on Mac OS X

At Crush + Lovely, we use Railsmachine's Moonshine to automate the configuration of our servers. When writing our deployment recipes, VMWare Fusion's ability to take snapshots and rollback to these snapshots is a huge timesaver because it takes just seconds to roll a server image to it's original state.

When you're just configuring a single server, having a static IP address for your server image isn't too important, but when you're configuring multi-server setups, it can be useful to duplicate a number of server images and give each a static IP address so you can consistently deploy to them.

Now open /Library/Application\ Support/VMware\ Fusion/vmnet8/dhcpd.conf. vmnet8 is the virtual interface for NAT networking in VMWare the guest machines. In this file, you'll see a subnet clause that looks something like this:

subnet 172.16.179.0 netmask 255.255.255.0 {
	range 172.16.179.128 172.16.179.254;
	option broadcast-address 172.16.179.255;
	option domain-name-servers 172.16.179.2;
	option domain-name localdomain;
	default-lease-time 1800;                # default is 30 minutes
	max-lease-time 7200;                    # default is 2 hours
	option routers 172.16.179.2;
}

Take note of the line starting with range. The IP addresses you will assign your guest machines will need to fall outside that range.

On OS X 10.9.1 (Maverick) + VMware Fusion 6.0.2 I found the dhcp.conf there:
/Library/Preferences/VMware\ Fusion/vmnet8

I've been trying to get this going for a couple days down OS X 10.9.1 (Maverick) w/ Ubuntu 12.04 LTS guest. My if I try this /etc/network/interfaces file on the guest...

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp

...I don't get any IPs (as I would expect). When I try this...

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.78.10
netmask 255.255.255.0
network 192.168.78.0
broadcast 192.168.78.255
gateway 192.168.78.1

...things seem to work properly. I get the IPs I would expect and can SSH into the box. The problem is that it hangs when I try to get outside to the Internet. I've tried adding a "dns-nameservers 192.168.78.2" and that seems to get me a little farther as it lets me resolve domain names to their IP address. That said it won't connect to anything. I can't "telnet 8.8.8.8 53" or "curl google.com" or anything as it just hangs. I sort of feel at the end of the rope. Any ideas?

Wahooo! Found the solution via a forked gist. :p I just had to restart services (https://gist.github.com/mgutz/1b8b5569190155dc31b9).

sudo /Applications/VMware\ Fusion.app/Contents/Library/services.sh --stop
sudo /Applications/VMware\ Fusion.app/Contents/Library/services.sh --start

Restarting w/VMWare Fusion 7

sudo /Applications/VMware\ Fusion.app/Contents/Library/services/services.sh --stop
sudo /Applications/VMware\ Fusion.app/Contents/Library/services/services.sh --start

thank you @bryancallahan that's exactly the piece I was missing, now everything works as it should :)

I was having a problem finding the correct "VM name" as I thought it was the name of the VM itself. Then I discovered the actual name that the DHCP Client was sending to the virtual DHCP Server was the system hostname, e.g. the output of the command hostname. To verify which name the system is using, look into the DHCP Client configuration.

ps -ef | grep dhc

In the output, find the name of the .conf file and look into it.

cat /var/lib/NetworkManager/dhclient-ens33.conf
...
send host-name "master";
...

The line shown shows you the exact hostname to use in Fusion's vmnet8/dhcpd.conf file as described above. Hope that helps.

VMWare Fusion 11.0.2 w/ OSX 10.14:

sudo /Applications/VMware\ Fusion.app/Contents/Library/services/services.sh --stop
sudo /Applications/VMware\ Fusion.app/Contents/Library/services/services.sh --start

For Windows hosts (at least tested with 10 and Fusion 12.1), you need to ensure that in the dhcp.conf the hostname is the Windows Computer Name as given in a cmd window by the hostname command.

      

host SQLServer-W10x64 {
    hardware ethernet 00:0c:29:9d:2a:38;
    fixed-address 172.16.179.102;
}

You might also need to delete the DHCP leases entry in /var/db/vmware/vmnet-dhcpd-vmnet1.leases or /var/db/vmware/vmnet-dhcpd-vmnet8.leases depending on whether you're dealing with the private/Host-only or NAT DHCP server.

There seem to be issues with Big Sur but I haven't upgraded yet. See here and here. Seems Big Sur doesn't allow Fusion to have its own DHCP servers and therefore manages it for Fusion.

Very helpful, especially the comments thanks.

This was the best resource I found online to help me configure a guest VM with a static IP on MacOS. It's kind of surprising VMWare doesn't have better documentation for Fusion's networking.

I totally agree... I spent so much time on setting static IPs on vms...
