[Openstack] numa+sriov issue
I'm building SR-IOV supported compute node on HP 360g8 hardware and i
have Qlogic interface card, my compute node has 32 core & 32GB memory.
when i launch vm-1 (with flavor 16 vCPU core) on openstack it launch
successful on numa0 node and working great. but when i launch vm-2
same flavor it start and then shutdown itself in few second, in-short
i am not able launch instance on numa1 node because my PCIe attach to
numa0node which i can see in lstopo command.
so at present i am going to lose half compute capacity if this is real
problem because i can't use numa1 to launch SR-IOV supported instance.
after google i found this link
and according this link if i can set
hw:pci_numa_affinity_policy=preferred in flavor it will allow me to
spin up instance across the numa node but somehow its not working and
still i am not able to spin up instance, (it start instance but then
Any idea what is wrong here?
