Hi,
Not something I found on this set; but on your older set, where you have
the experimental 'live' ram transfer; we found a test that was slowed
down (5x) by the calls to 'colo_need_live_migrate_ram'; even if it decides
not to send any RAM in the live phase, the call to 'qemu_savevm_state_pending'
can be really expensive.
Just thought it worth mentioning.
Dave
