Multi VM in one Vagrantfile. Could I set different memory size for each of them?

Question

config.vm.define :web do |web_config|     web_config.vm.box = "saucy"     web_config.vm.host_name = "web"     web_config.vm.network "private_network", ip:"192.168.100.10" end  config.vm.define :db do |db_config|     db_config.vm.box = "saucy"     db_config.vm.host_name = "db"     db_config.vm.network "private_network", ip:"192.168.100.20" end  config.vm.provider :virtualbox do |vb|     vb.customize ["modifyvm", :id, "--memory", "1024"]     vb.customize ["modifyvm", :id, "--cpus", "2"] end 

I have config two VM, 'db' and 'web'. Could I set different memory size for different VM?

You can do that by moving the vm.provider definition inside each of the vm.define blocks. For example this configuration sets the memory to 2048MB for "web" and 1024MB for "db":

# -*- mode: ruby -*- # vi: set ft=ruby :  Vagrant.configure(2) do |config|   config.vm.box = "ubuntu/trusty64"    config.vm.define :web do |web_config|       web_config.vm.host_name = "web"       web_config.vm.network "private_network", ip:"192.168.100.10"       web_config.vm.provider :virtualbox do |vb|           vb.customize ["modifyvm", :id, "--memory", "2048"]           vb.customize ["modifyvm", :id, "--cpus", "2"]       end   end    config.vm.define :db do |db_config|       db_config.vm.host_name = "db"       db_config.vm.network "private_network", ip:"192.168.100.20"       db_config.vm.provider :virtualbox do |vb|           vb.customize ["modifyvm", :id, "--memory", "1024"]           vb.customize ["modifyvm", :id, "--cpus", "2"]       end   end end 

Note: This example (like many in the Vagrant docs) will only work for VirtualBox. If you wanted your Vagrantfile to also work with VMware or another provider, the customization parameters would be listed separately. For example:

x.vm.provider "vmware_fusion" do |v|   v.vmx["memsize"] = "3000" end x.vm.provider :virtualbox do |v|   v.customize ["modifyvm", :id, "--memory", "3000"] end
