HugePages - can't start guest that requires them
...39;m getting "libvirtd[5788]: Failed to autostart VM 'atlas': internal
error: Unable to find any usable hugetlbfs mount for 16777216 KiB"
where atlas is one of my guests and 16777216 KiB is the amount of
memory I'm trying to give to the guest.
Yes, i can see the hugepages via numastat -m and hugetlbfs is mounted
via /dev/hugepages and there is a dir structure
/dev/hugepages/libvirt/qemu (it's empty).
HugePages is big enough to accommodate the 16G i'm allocating... and
changing the perms on that directory structure to 777 doesn't work
either.
Any help is much apprec...

Re: HugePages - can't start guest that requires them
*facepalm*
Now that I'm re-reading the documentation it's obvious that <page/>
and @nodeset are for the guest, "This tells the hypervisor that the
guest should have its memory allocated using hugepages instead of the
normal native page size." Pretty clear there.
Thank you SO much for the guidance, I'll return to my tweaking. I'll
report back here with my results.

<page size='16777216' unit='KiB' nodeset='0'/>
This means you want the guest's memory to be allocated from 16GiB
hugepages. You probably wanted to put this there:
<page size='2' unit='MiB' ...
