Best Practices

Resource Allocation

• CPU and Memory:
  • Allocate resources based on the guest OS requirements.

    • NAT: Easy setup, suitable for most cases.
    • Bridged Adapter: VM appears as a separate device on the network.
    • Host-Only Adapter: VM communicates only with the host and other VMs.

Using Snapshots

• Purpose of Snapshots:
  • Save the state of a VM at a specific point in time.
  • Useful before making significant changes or testing.
• Best Practices:
  • Limit the number of snapshots to avoid performance issues.
  • Do not use snapshots as a replacement for backups.

Keeping VirtualBox Updated
