There is nothing special needed for migration when compared to running a
VM.
With new daemons you need 'virtqemud' to manage the VM and optionally
'virtnetworkd' if the VM uses libvirt-managed networks, 'virtstoraged'
if it uses libvirt managed storage, and/or 'virtsecretd' if it uses
secrets storage.
Configuration of daemon options moved to the appropriate per-daemon
config file.
I have a feeling - have not tested all thoroughly - that
specific modules/daemons need to be up & running for
specific methods of transportation.
Say..
migration with 'qemu+tls' fails if receiving node does not
have 'virtproxyd-tls.socket' up&running,
even though 'virtproxyd.socket' & 'virtqemud.service' are
running on that node.
So I wonder - if that is the business logic here - if man
pages which are already are very good, could enhance even
more to explain those bits too... A suggestion.
