I think that virsh command should work. Look at
/var/log/libvirt/qemu/$vmname.log on both the source host and the destination
host.
I tried to run the migration but it is not doing profitably.I also used virtual
machine manager but it is giving me " unsafe operation"

Like the error says, your disks need to have cache=None or libvirt won't allow
the migration. You can change that setting per disk in the VM details UI in
virt-manager.
