In general, a force does work when it produces a displacement along its line of action. When we talk about virtual work, we're making those displacements infinitesimally small.
We can use virtual work to solve for the forces in a system without needing to solve for all of the support reactions. +
For example, if a truss is completely pinned on one end, it doesn't move, which means there is no virtual work completed on that pin because there are no virtual displacements ((
