Joining Xen

The next step will guide you through a standard setup to add a fourth compute node in our test environment. The latter host will run nova-compute service supporting XenServer hypervisor features with an installed Neutron agent service. The new compute node will have similar hardware requirements to the previous installed compute nodes in the test environment, as follows:

  • Memory: At least 4 GB RAM
  • Processor: At least 4 64-bit x86 CPUs 
  • Disk space: At least 40 GB free disk space
  • Network: At least two NICs

The following excerpt will be added to the vagrant file in our test environment:

 ... # Compute Node XenServer config.vm.define :cn04 do |cn04| cn04.vm.hostname= "cn04" cn04.vm.provider "virtualbox" do |vb| vb.customize ["modifyvm", ...
