Hello it worked for me after removing the following parameter from
/etc/nova/nova.conf file

[root@OSKVM1 ~]# cat /etc/nova/nova.conf|grep hw_disk_discard

#hw_disk_discard=unmap


Though as per ceph documentation, for KILO version we must set this
parameter. I am using Liberty but i am not sure if this parameter is
removed from Liberty. If that is the case please update the documentation.


KILO

Enable discard support for virtual machine ephemeral root disk:

[libvirt]

...

hw_disk_discard = unmap # enable discard support (be careful of performance)
