Alexandre Derumier 7023f3ea16 add hugepages option
vm configuration
----------------
hugepages: (any|2|1024)

any: we'll try to allocate 1GB hugepage if possible, if not we use 2MB hugepage
2: we want to use 2MB hugepage
1024: we want to use 1GB hugepage. (memory need to be multiple of 1GB in this case)

optionnal host configuration for 1GB hugepages
----------------------------------------------
1GB hugepages can be allocated at boot if user want it.
hugepages need to be contiguous, so sometime it's not possible to reserve them on the fly

/etc/default/grub : GRUB_CMDLINE_LINUX_DEFAULT="quiet hugepagesz=1G hugepages=x"
