Configuration

The inventory may define these hosts to run:

• hypervisors: Set of hosts to launch virtual machines

Components of VM

Each components of VM should have a VirtIO interface (for example the network or the disk).

Some examples are available here.

Troubleshooting

Bootloader

If the VM is in UEFI mode, it's possible that it doesn't boot because the firmware is not the same. Follow this steps:

1. Boot the machine on the cluster
2. Re-install the bootloader
3. Update the bootloader configuration

Deployment of VM with Ansible

The playbook ansible/playbooks/cluster_setup_deploy_vms.yaml is used to deploy a virtual machine. There is an ansible library (ansible/library/cluster_vm.py) to wrap vm_manager.

Configuration

The inventory must define these hosts to run this step:

• VMs: Sets of hosts to launch on hypervisors

Before starting, make sure there is enough space in /home and /tmp.
