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.
