What you can do is create a new VM from an existing snapshot, something like this: #!/bin/sh -ex url="https://ovirt.example.com/ovirt-engine/api" user="admin@internal" password="******" curl \ --verbose \ --insecure \ --request POST \ --header "Accept: application/xml" \ --header "Content-Type: application/xml" \ --user "${user}:${password}" \ --data " <vm> <name>myclone</name> <cluster id='00000001-0001-0001-0001-000000000171'/> <snapshots> <snapshot id='f09a98fd-2c7e-40eb-a9ae-6b7f86412bb0'/> </snapshots> </vm> " \ "${url}/vms" You need to modify that script with your URL, user name, password, cluster and snapshot id. The statistics are available in the "statistics" sub-resource. For example, if you want to get the statistics of a host you can do the following: #!/bin/sh -ex url="https://ovirt.example.com/ovirt-engine/api" user="admin@internal" password="******" curl \ --verbose \ --insecure \ --request GET \ --header "Accept: application/xml" \ --user "${user}:${password}" \ "${url}/hosts/40cc4c33-2560-4516-b028-1d59638139c3/statistics" There you will find different statistics, like "memory.total", "memory.used", etc. Take a look. Once you know what statistic you want you can get its details like this: curl \ --verbose \ --insecure \ --request GET \ --header "Accept: application/xml" \ --user "${user}:${password}" \ "${url}/hosts/40cc4c33-2560-4516-b028-1d59638139c3/statistics/7816602b-c05c-3db7-a4da-3769f7ad8896" This can be cumbersome to do with a shell script, so you may want to use the Python or Java SDKs, or just use directly the ovirt-shell: $ ovirt-shell --insecure URL: https://ovirt.example.com/ovirt-engine/api Username: admin@internal Password: ****** [oVirt shell (connected)]# show statistic memory.total --host-identifier myhost id : 7816602b-c05c-3db7-a4da-3769f7ad8896 name : memory.total description : Total memory host-id : 40cc4c33-2560-4516-b028-1d59638139c3 type : GAUGE unit : BYTES values-type : INTEGER values-value-datum: 2099249152 -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.
