      arch_init: align MR size to target page size · 0851c9f7
      Michael S. Tsirkin 提交于
      Migration code assumes that each MR is a multiple of TARGET_PAGE_SIZE:
      MR size is divided by TARGET_PAGE_SIZE, so if it isn't migration
      never completes.
      But this isn't really required for regions set up with
      memory_region_init_ram, since that calls qemu_ram_alloc
      which aligns size up using TARGET_PAGE_ALIGN.
      
      Align MR size up to full target page sizes, this way
      migration completes even if we create a RAM MR
      which is not a full target page size.

      Force auto-convegence of live migration · 7ca1dfad
      Chegu Vinod 提交于
      If a user chooses to turn on the auto-converge migration capability
      these changes detect the lack of convergence and throttle down the
      guest. i.e. force the VCPUs out of the guest for some duration
      and let the migration thread catchup and help converge.
      
      Verified the convergence using the following :
       - Java Warehouse workload running on a 20VCPU/256G guest(~80% busy)
       - OLTP like workload running on a 80VCPU/512G guest (~80% busy)
      
      Sample results with Java warehouse workload : (migrate speed set to 20Gb and
      migrate downtime set to 4seconds).
