After IRC, vagrant is probably my most important development tool, mostly because I like to use and investigate openstack, which means using a lot of virtual machines.
Recently Hashicorp released Vagrant 1.1 which introduces the idea of providers. Previously vagrant only supported virtualbox, but now, with 1.1, plugins can be written to support almost any virtualization system that has a command line or API interface of some sort.
For example:
The provider I’m going to focus on here is vmware fusion.
One of the things I’ve learned about using brand new technologies is that they often don’t work and/or don’t have any documentation, which frankly are about the same thing to me. That sounds like a kind of grumpy thing to say, but I’m kind of grumpy today. :)
Regardless, I went ahead and bought vmware fusion (which is cheap, BTW, at $49) and also the vagrant vmware_fusion plugin (which is $79).
I think this is the first time that I’ve encountered a plugin that was more expensive than the actual application it was plugging into, but I can understand the pricing because Fusion is probably under-valued, or at least under-priced. Plus the $79 goes towards the development of vagrant, which I use a lot.
Recently I deployed packstack via vagrant and virtualbox, and I wanted to do the same with vmware_fusion, but I ran into a few problems, which I’m going to spend the rest of the post detailing.
NOTE: I should say that nothing here is the vmware_fusion plugins fault. I’m not blaming the plugin at all. Rather just detailing some of the pain points I’ve encountered, which will no doubt disappear as more people use vmware fusion and vagrant together, and as I get my act together. I’ll try to update this post as I find out new information. :)
I have both vmware fusion and virtualbox installed on my macbook retina. Unfortunately, virtualbox has an iron grip on its networks.
VirtualBox hangs on to its network devices (“vboxnet”) for dear life. I haven’t figured out yet how to actually get rid of them except restarting your computer. – Mitchell Hashimoto
If you encounter the below error, either change subnets (perhaps in virtualbox, perhaps in the vagrantfile, not sure) or reboot.
$ vagrant up apis --provider=vmware_fusion
Bringing machine 'apis' up with 'vmware_fusion' provider...
[apis] Verifying vmnet devices are healthy...
The VMware network device 'vmnet2' can't be started because
its routes collide with another device: 'vboxnet'. Please
either fix the settings of the VMware network device or stop the
colliding device. Your machine can't be started while VMware
networking is broken.
Again, not vmware_fusion’s fault, but still a pain. I can’t simply un-install virtualbox…yet.
Often we want to change the settings in the virtual machine, settings such as memory, number of cpus, etc.
Unfortunately vmx is an undocumented format.
VMX is an undocumented format. You’ll have to google, unfortunately. :) – Mitchell Hashimoto
But at the very least here is how to set memory:
config.vm.provider :vmware_fusion do |p|
p.vmx['memsize'] = '2048'
end
As more people use vmware_fusion there will be better documentation on vmx settings.
While Hashicorp has conveniently provided a base precise64 box for vagrant, there isn’t an official centos box. I have previously tried to create a centos6 box for vagrant, but haven’t had much luck, and that was with vagrant < 1.1 and there is even less documentation on the process now.
Then I noticed that vagrantbox.es (which is a very handy site!) has a centos6 box for vmware_fusion, so I grabbed that:
Unfortunately it doesn’t seem to work when multiple interfaces are specified in the vagrantfile, so that doesn’t help me much on my quest to run packstack in vmware_fusion. If anyone knows of a good centos6 box, or notices that I’m doing something wrong, please let me know!
Here’s the networking part of the config:
config.vm.network :private_network, ip: "172.10.0.200", :netmask => "255.255.0.0"
config.vm.network :private_network, ip: "10.10.0.200", :netmask => "255.255.0.0"
Let’s boot it:
$ vagrant up --provider=vmware_fusion
Bringing machine 'default' up with 'vmware_fusion' provider...
[default] Cloning Fusion VM: 'centos65fusion'. This can take some time...
[default] Verifying vmnet devices are healthy...
[default] Preparing network adapters...

[default] Waiting for the VM to finish booting...
[default] The machine is booted and ready!
[default] Forwarding ports...
[default] -- 22 => 2222
[default] Configuring network adapters within the VM...
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
/sbin/ifup eth1 2> /dev/null
Ooops, shouldn’t be seeing the failed command.
What’s the networking like?
$ vagrant ssh

Nope that’s not what I wanted at all.
Ok, now let’s use the exact same vagrantfile but with the offical vmware_fusion ubuntu box.
config.vm.box = "precise64"

That’s what I expect to see.
UPDATE (April 18th, 2013): This Vagrantfile now doesn’t seem to work with Vagrant 1.2
I have been searching for good examples of vagrantfiles that use vmware_fusion.
So far I’ve just found this one:
But I will keep an eye out for other examples.
This is a new one…now this can’t be virtualbox’s fault.
$ vagrant up --provider=vmware_fusion
Bringing machine 'percona0' up with 'vmware_fusion' provider...
Bringing machine 'percona1' up with 'vmware_fusion' provider...
Bringing machine 'percona2' up with 'vmware_fusion' provider...
Bringing machine 'haproxy0' up with 'vmware_fusion' provider...
Bringing machine 'haproxy1' up with 'vmware_fusion' provider...
[percona0] Cloning Fusion VM: 'precise64'. This can take some time...
[percona0] Verifying vmnet devices are healthy...
The VMware network device 'vmnet1' can't be started because
its routes collide with another device: 'vmnet13'. Please
either fix the settings of the VMware network device or stop the
colliding device. Your machine can't be started while VMware
networking is broken.
Instructions from Mitchell, edit /Library/Preferences/VMware\ Fusion/networking and:
bq.. Get rid of all the lines in that file except the ones that start with “answer VNET_1” or “answer VNET_8”. We want to keep those, as they’re the default networks that ship with Fusion. After that, open VMware Fusion.app, then run these commands in a separate terminal:
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli –stop sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli –configure sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli –start
Then run
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli –status
And tell me the output. Should only have the vmnet1/vmnet8 devices. After THAT you shoudl be good to go again.
VMware networking is an absolute nightmare. - Mitchell
It sucks that it’s an edge case, but I still hope that there is some code added to help in situations like this. Thanks to Mitchell for responding on the mailing list, as now I can continue on with other problems. :)
I love vagrant, but am having a heck of a time with vmware_fusion and centos6. Having said that, I KNOW that things are going to get better as I learn and as more people start using vagrant and vmware_fusion.
Hats off to Mitchell for creating a great development tool, one that I use every day!
