Ah - that actually won't work. There has to be space for PCI MMIO
decode below 4GB, so it's usually best to use up to say 2 or 3GB of RAM
below the 4GB mark, leaving 1GB for PCI decode, and then put the
remainder of your memory above 4G e.g. for 4GB total RAM, and using 2GB
below 4G
-m 2048 -M 2048
and an example 8G system:
-m 2048 -M 6144
We should really error out on values too large for the '-m' parameter.
later,
Peter.
