[ovirt-devel] No response for post using curl for The Backup and Restore API oVirt API

I have 2 virtual machines in my ovirt open virtualisation manager.The name of first virtual machine is backupvm and the name of second virtual machine is secondvm .I have created many snapshot shot of secondvm I want to convert a particular snapshot ofsecondvm using the ovirt api to secondvm backup and attach it to backupvm The link of the api is https://ovirt.org/documentation/admin-guide/chap-Backups_and_Migration.ht... .I want to run the fourth step which says. Attach the snapshot to the backup virtual machine and activate the disk: POST /api/vms/22222222-2222-2222-2222-222222222222/disks/ HTTP/1.1 Accept: application/xml Content-type: application/xml <disk id="11111111-1111-1111-1111-111111111111"> <snapshot id="11111111-1111-1111-1111-111111111111"/> <active>true</active> </disk> .I want to attach this snapshots after converting them to backups of vms and then attach to vm named backupvm.The api for this is mentioned as The id of secondvm is a88a79ab-1f0c-4f32-bdaa-abc8109b3c0d and the id of backupvm is a88a79ab-1f0c-4f32-bdaa-abc8109b3c0d.The id of snapshot is 804cb937-5961-4a55-a453-74932c508dd6 and id of disk is e6c623e3-31d8-4554-ad5a-2b581914494b I have written a curl command for this as curl -u 'username:password' -H "Accept: application/xml" -H "Content-type: application/xml" -X POST -d '<disk id="e6c623e3-31d8-4554-ad5a-2b581914494b"> <snapshot id="804cb937-5961-4a55-a453-74932c508dd6"/> <active>true</active> </disk>' https:<url>/ovirt-engine/api/vms/a88a79ab-1f0c-4f32-bdaa-abc8109b3c0d/disks/ ; I expect the vm snapshot to be attached to backupvm.But i am not getting any response .Hence i am under the assumption that it is not working.. What modification should i make in the curl command to get it working In the figure below secondvm is labelled as bobcarenewvm https://i.stack.imgur.com/LC3An.png https://i.stack.imgur.com/Lgozu.png https://i.stack.imgur.com/efQrf.png https://i.stack.imgur.com/3wAyA.png Please help me, Thanks and Regards, Midhun.
