We have seen a situation when migrating about 50 VMs at once where some
of them fail. I think this is because they are dirtying pages faster than
they can be transmitted.
What algorithm controls when migration fails in this way, and is it
tunable?
I am fully aware one answer to this question is "do not attempt to
migrate 50 busy VMs through a single 1GB/s NIC".
