Discussed with the Nova team and this is a know issue at the moment - mixing instance types with and with NUMA configuration features such as hugepages will create this type of issue.
The placement API (which is used for scheduling) does not track different pagesizes so can't deal with this scenario today. Feedback indicated that using flavors with explicit configuration to use small pages might do the trick in terms if triggering the codepath through the NUMA cell configuration in Nova. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1950186 Title: Nova doesn't account for hugepages when scheduling VMs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1950186/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
