In some cases libvirt may refuse to migrate the domain because doing so may
lead to potential problems such as data corruption, and thus the migration is
considered unsafe. For QEMU domain, this may happen if the domain uses disks
without explicitly setting cache mode to "none". Migrating such domains is
unsafe unless the disk images are stored on coherent clustered filesystem,
such as GFS2 or GPFS. If you are sure the migration is safe or you just do not
care, use I<--unsafe> to force the migration.
The I<desturi> is the connection URI of the destination host, and
I<migrateuri> is the migration URI, which usually can be omitted.
I<dname> is used for renaming the domain to new name during migration, which
