      Force auto-convegence of live migration · 7ca1dfad
      Chegu Vinod authored
      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).

      hw: move headers to include/ · 0d09e41a
      Paolo Bonzini authored
      Many of these should be cleaned up with proper qdev-/QOM-ification.
      Right now there are many catch-all headers in include/hw/ARCH depending
      on cpu.h, and this makes it necessary to compile these files per-target.
      However, fixing this does not belong in these patches.
