A viable scenario for globular cluster formation is suggested in a cold dark matter model. In this scenario the smaller scale fluctuations superposed on a proto-galaxy will form proto-dwarf-galaxies. In their multi-phase ISM the warm clouds, which are thermally stable and gravitationally marginally stable with appropriate masses and metallicities, might be the proper progenitors of globular clusters. In the virialization of a proto-galaxy, these dwarf galaxies will acquire kinetic energy and collide with each other. As strong external disturbances, these collisions will cause a short timescale thermal instability, and further stimulate gravitational instability which is necessary for the transformation of progenitors into globular clusters.
