When we try to migrate vm, we check if it contains only devices
that are able to migrate. If a hostdev device is not able to
migrate we raise an error with <hostdev/>, but it can actually be
<interface/>, so we need to check if hostdev device was created
by us from interface and show the right error message.

Small nit, I wonder whether we should report actual type here. Looking
into virDomainNetDefFormat() it looks like for a running VM we do report
actual type (unless inactive or migratable XML was requested). Thus I
think the error message should follow that logic. Otherwise we might
report "cannot migrate a domain with interface type=network" while in
fact in 'virsh dumpxml' there is just interface type='hostdev' (the
type='network' is in inactive XML).
Laine, what's your opinion?
