Using XMM-Newton data; we study for the first time the X-ray emission of HM1 and IC 2944/2948. Low-mass; pre-main-sequence objects with an age of a few Myr are detected; as well as a few background or foreground objects. Most massive stars in both clusters display the usual high-energy properties of that type of objects; though with log [LX/LBOL] apparently lower in HM1 than in IC 2944/2948. Compared with studies of other clusters; it seems that a low signal-to-noise ratio at soft energies; due to the high extinction; may be the main cause of this difference. In HM1; the two Wolf-Rayet stars show contrasting behaviors: WR89 is extremely bright; but much softer than WR87. It remains to be seen whether wind-wind collisions or magnetically confined winds can explain these emissions. In IC 2944/2948; the X-ray sources concentrate around HD 101205; a group of massive stars to the north of this object is isolated; suggesting that there exist two subclusters in the field-of-view. © ESO; 2013;
