yes.
But this is a little bit more complex to manage. 

In this case we need to try to alloc pages before generate the qemu command line
as we generate qemu command line, with 1GB or 2M hugepagemount point.

(I have in mind to alloc pages after config_to_command, to avoid alloc pages if config is wrong)

Why not. Also, allocation 1GB pages may can fail due to fragmentation, while 
allocation of 2MB pages still work?
