Hi,

My host os is CentOS6, to avoid being affected by the unstable Transparent 
Hugepage feature, I started to pre-allocate memory for qemu by using the kernel 
native hugepage.

What I’m asking here is, if the guest set huge page inside itself as well (very 
large guest, 32 core 128G for instance), what would happen?

Will the performance keeps on rising a little bit?

Is it really necessary to set hugepage for qemu anyway?


Regards, 
Bob
