Automated installs on Xenserver

This section contains info about automated installations on Xenserver, using Ansible.

Predefined VM flavours

vmtypes.csv contains settings for different flavours of VM's. It is possible to override everything (disk size, ram, cpu weight or count etc.), by supplying the variables on the command line, and the predefined types can be changed in vpstypes.csv if it's a more permanent change.

VM configs (vps types)

These predefined VM configs get loaded automatically

  • VM-S - 1GB RAM, 25GB disk, 1 CPU, CPU weight: 64
  • VM-M - 2GB RAM, 50GB disk, 1 CPU, CPU weight: 256
  • VM-L - 4GB RAM, 100GB disk, 1 CPU, CPU weight: 1024
  • VM-XL - 8GB RAM, 200GB disk, 1 CPU, CPU weight: 4096
  • VM-XXL - 16GB RAM, 500GB disk, 1 CPU, CPU weight: 16384
  • VM-XXXL - 32GB RAM, 1TB disk, 1 CPU, CPU weight: 65536

Static IP adresses

This playbook uses static IP adresses for now, but support for DHCP assigned addresses is planned.

Usage

The following variables are required:

  • hostname
  • vm_name
  • vps_type
  • sr_name
  • vm_template

The following variables has sane defaults, set by the VPS types CSV file. But you can change them, if you want to:

  • memory
  • disksize
  • cpu_weight
  • vcpu_count

The hosts file contains a list of Xenservers. When running the script, you have to limit the hosts it's being run on, to the one you wish the VPS to run on. If you have a Xenserver pool, please use the poolmaster.

Example

Edit the file xenserver_vars.yml and run

ansible-playbook -i ./hosts xenserver-vm-deploy.yml

or

ansible-playbook -i hosts --limit xen01 xenserver-vm-deploy.yml -e "hostname=vm01 vm_name=vm01 vps_type=VM-S sr_name=ssd_storage vcpu_count=2 vm_template='Debian9_template'"
