  • Thread-topic: Memory allocation

I¹m sure this has been asked a bazillion times on this list, but I couldn¹t
find a definitive answer:

4GB ram,  3 domU¹s

I boot each domU up with 1GB ram, then mem-max and mem-set them to 2GB
(which obviously exceeds physical memory limit). They all grow to 2048. It
seems that you won¹t see the memory hit 2gb on a domU until it has eaten up
more than what it initially booted with, which is fine. The question I have
is what would happen if all three domU¹s tried using 2GB?

Thanks,

BJ Badyk
