Deployment Guide with Repositories and Retention Policies
Setting Up a VirtualBox Repository
A repository is a centralized storage location for VM images and other VirtualBox-related files. Setting up a repository involves creating a shared folder on the host machine and configuring VirtualBox to use it as the default repository location.
Configuring Retention Policies
Retention policies determine how long VM snapshots and other data are retained on the system. Configuring retention policies involves setting the snapshot retention period and the maximum number of snapshots to retain.
