This are settings for the domain that you can change before the domain
starts. "memory" is the maximum it can reach and "currentMemory" is
what the domain will have it cut down to using a memballoon.
However somehow we can observe RSS greater than the "memory", which is
supposed to be the maximum it can reach. Have you ever seen this happen and
could you provide us any comment?
RSS from where? Are you looking at the memory usage by the qemu process
in the host, or the amount of memory in use by the guest? The qemu
process uses more memory than what it makes available to the guest.
