Hi,
I would like to create the following functions using the ovirt api
1. Rebuild VM
What do you exactly mean by "rebuild vm"?
2. Restore the screenthots of one vm to another vm
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> " \ "${url}/vms" You need to modify that script with your URL, user name, password, cluster and snapshot id.
3. Display cpu,network etc usages
The statistics are available in the "statistics" sub-resource. For example, if you want to get the statistics of a host you can do the following: #!/bin/sh -ex url="https://ovirt.example.com/ovirt-engine/api" user="admin@internal" password="******" curl \ --verbose \ --insecure \ --request GET \ --header "Accept: application/xml" \ --user "${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
I couldn't find out any direct api method to do the above, Is it possible to do these operations using api ? If anyone knows it please help me to sort out it.
