Hi, I am going to commit a change soon that simplifies how memory is assigned to a VM from a command line perspective. At the moment if you want to create a VM with say 8GB of memory you need to express this as "-m 2048 -M 6144" or "-m 1024 -M 7168" or some split that adds up to 8192MB. This is very flexible but is also very confusing to most users who don't know or care about the location of the PCI hole. I am going to change this so that the memory size is specified entirely with the "-m <memsize>" option and the "-M" option will disappear altogether. Of course, this means that scripts using "-M" will break and hence this heads up. I did consider making this a backward compatible change but given the stage of development of bhyve it seemed early to start accumulating compatibility crud. best Neel
