Wondering if Austin or Bin can provide some insight here.
Hi all:
I’m testing pci-passthrough with a AIO stx node(iso version:20190607T142331Z), after install completed,
I found that there’s not enough memory reversed for my vms(server total memory is 64G,but only 7-8G can be allocated for vms),
Checked node with `system host-memory-list controller-0` and find that hugepages was configured and I did’t deply dpdk-ovs.
Here are my questions:
1.
Did stx turn on hugepage as default? Can this feature be tured off to get all the reserved memory for my vms (I don’t need dpdk-ovs)?
2.
If hugepage is necessary, refer to
https://docs.openstack.org/nova/pike/admin/huge-pages.html ,I’ve Customized flavor for huge pages allocations with `openstack flavor set m1.large --property hw:mem_page_size=large`
But it did’t work (vm boot successfully , no memory allocated from reseved hugepages). Did I do it in right way? Where can I trace the error?
Here ‘re the detail of my node:
[wrsroot@controller-0 ~(keystone_admin)]$ system host-memory-list controller-0
