Hi Xunlei,
Thanks for the initiative on it.

e.g. some x86_64 large machine : 24TB RAM, nearly 1024 cpus, with the

"crashkernel=512M,high crashkernel=256M,low nr_cpus=4", then it works properly.
So, if we have only 1G of RAM and all other configuration as above, then
will that machine boot with nr_cpus=2?
I mean, if there is some other factor than memory which governed minimum
number of CPUs then automating nr_cpus on the basis of memory might fail
in some cases.
