Thank you for your reply. I know nothing about system internals. Is it
too much work to implement it or just nobody from developers need it
thus nobody write the code? Virtualization is more and more popular
these days so I think it will be useful for many users.
In my opinion, both would be big changes.
At the moment we do not have any support for offlining / onlining CPUs
and that would involve a lot of careful changes like safely updating CPU
sets, various CPU masks, etc.
Ditto for the memory. Updating page arrays, free memory accounting
structures, possibly some memory maps, etc.
Definitely not a weekend project.
Thank you again. It really seems too complicated.
