Jason Wang points out that it's vary hard for users to build an array of stat names. The naive thing is to use VIRTIO_BALLOON_S_NR but that breaks if we add more stats. Let's add an array of reasonably readable names.

Here is a set of small patches that enables hugetlb on PV machines. They are against xen-unstable and linux-2.6.18-xen. The patches are specifically for x86_64. I originally had these patches working back in May, but recently for some reason my machine now refuses to boot the baseline xen-unstable, so I''ve been unable to verify them....

Has anyone tried getting wine to use HugeTLB yet? I see a real need for this for games.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Thanks a lot you two, yes hugetlbfs is not mounted, when libvirtd is started… It was a long night. Did put it to fstab and since I do not allocate them on regular boots, it won’t eat my ram (that was the main consideration for doing it like this). As a last means before going to sleep, I added <qemu:arg value='-numa'...
