CC-ing libvirt-users 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. - Cole
Hello, i migrated the vm to the dsetination but when i remigrate to its original host is gives me.

That message should be self explanatory: the destination host needs a FQDN (fully qualified domain name), but the equivalent of hostname --fqdn is 'localhost'. You need to fix that for migration to work. - Cole
