How do I increase the RAM and set up host-only networking in Vagrant

Question

I would like to increase the RAM to at least 1 GB and I would like to configure    Host-Only    networking to use  199 188 44 20    This is my Vagrantfile     - - mode  ruby - -   vi  set ft ruby    Vagrant  Config run do  config       config vm customize   modifyvm    id   --memory   1024       config vm network  hostonly   199 188 44 20       config vm define  web do  web config          web config vm box    lucid32          web config vm forward port 80  8080          web config vm provision  puppet do  puppet              puppet manifests path    manifests              puppet manifest file    lucid32 pp          end     end      config vm define  web2 do  web2 config           web2 config vm box    lucid32          web2 config vm forward port 80  8081          web2 config vm provision  puppet do  puppet              puppet manifests path    manifests              puppet manifest file    myweb pp          end     end end   However  when I run vagrant up I am getting      The VM failed to remain in the  running  state while attempting to boot  This is normally cause by a misconfiguration or host system incompatibles  Please open the VirtualBox GUI and attempt to boot the virtual machine manually to get more informative error message   And  I am getting a connection refuse error when I try to log in to the VM

I could not get any of these answers to work. Here's what I ended up putting at the very top of my Vagrantfile, before the Vagrant::Config.run do block:

Vagrant.configure("2") do |config|
  config.vm.provider "virtualbox" do |vb|
    vb.customize ["modifyvm", :id, "--memory", "1024"]
  end
end

I noticed that the shortcut accessor style, "vb.memory = 1024", didn't seem to work.

Since Vagrant 1 1 customize option is getting VirtualBox-specific   The modern way to do it is   config vm provider  virtualbox do  vb    vb customize   modifyvm    id   --memory    256   end

To increase the memory or CPU count when using Vagrant 2  add this to your Vagrantfile  Vagrant configure  2   do  config        usual vagrant config here      config vm provider  virtualbox  do  v          v memory   1024         v cpus   2     end end

You can easily increase your VM s RAM by modifying the memory property of config vm provider section in your vagrant file   config vm provider  virtualbox  do  vb   vb memory    4096  end   This allocates about 4GB of RAM to your VM  You can change this according to your requirement  For example  following setting would allocate 2GB of RAM to your VM    config vm provider  virtualbox  do  vb   vb memory    2048  end   Try removing the config vm customize   modifyvm    id   --memory   1024  in your file  and adding the above code   For the network configuration  try modifying the config vm network  hostonly   199 188 44 20  in your file toconfig vm network  private network   ip   199 188 44 20

You can modify various VM properties by adding the following configuration  see the Vagrant docs for a bit more info        Configure VM Ram usage   config vm customize                            modifyvm    id                           --name    Test Environment                            --memory    1024                            You can obtain the properties that you want to change from the documents for VirtualBox command-line options    http   www virtualbox org manual ch08 html vboxmanage-modifyvm   The vagrant documentation has the section on how to change IP address   Vagrant  Config run do  config    config vm network  hostonly   192 168 50 4  end   Also you can restructure the configuration like this  ending is do with end without nesting it  This is simpler   config vm define  web do  web config      web config vm box    lucid32      web config vm forward port 80  8080 end web config vm provision  puppet do  puppet      puppet manifests path    manifests      puppet manifest file    lucid32 pp  end
