I<--copy-storage-all> indicates migration with non-shared storage with full
disk copy, I<--copy-storage-inc> indicates migration with non-shared storage
with incremental copy (same base image shared between source and destination).
I<--verbose> displays the progress of migration.
I<--change-protection> enforces that no incompatible configuration changes
will be made to the domain while the migration is underway; this flag is
implicitly enabled when supported by the hypervisor, but can be explicitly
used to reject the migration if the hypervisor lacks change protection
support. I<--verbose> displays the progress of migration.
The I<desturi> is the connection URI of the destination host, and
I<migrateuri> is the migration URI, which usually can be omitted.
