Issue

  • What is difference when using flavor property hw:mem_page_size=large and hw:mem_page_size=1G.

  • We use the following kernel parameter later on:

TRIPLEO_HEAT_TEMPLATE_KERNEL_ARGS=" default_hugepagesz=1GB hugepagesz=1G hugepages=106 intel_iommu=on intel_iommu=pt vfio_iommu_type1.allow_unsafe_interrupts=1 nmi_watchdog=0 transparent_hugepage=never intel_idle.max_cstate=0 processor.max_cstate=1 idle=mwait nohpet nosoftlockup isolcpus=1,3-35,37,39-71 "
