Read the first 6 OpenStack Compute (Nova) flashcards as text

  1. Which OpenStack service manages the lifecycle of virtual machine instances?

    Answer: Nova

    Nova is the OpenStack Compute service responsible for creating, scheduling, and managing virtual machine instances.

  2. What is a Nova 'flavor' in OpenStack?

    Answer: A hardware profile defining vCPUs, RAM, and disk size for VM instances

    A Nova flavor defines the virtual hardware profile (vCPUs, RAM, disk) of a VM instance, analogous to an EC2 instance type.

  3. What is Nova's scheduler responsible for?

    Answer: Selecting the most appropriate compute host for a new VM based on filters and weights

    The Nova scheduler selects the best compute host for a new instance using configurable filters and weighers.

  4. What hypervisor does Nova use by default in most production deployments?

    Answer: KVM (Kernel-based Virtual Machine)

    KVM is the most widely deployed hypervisor for OpenStack Nova in production environments due to its performance and Linux integration.

  5. What is the purpose of Nova's 'nova-conductor' service?

    Answer: Providing a database access proxy to prevent compute nodes from directly accessing the Nova database

    nova-conductor acts as a database proxy layer, preventing compute nodes from having direct database access for improved security.

  6. What is 'live migration' in Nova?

    Answer: Migrating a running VM instance from one compute host to another without downtime

    Live migration in Nova moves a running VM from one compute host to another with minimal or zero downtime.
