Created attachment 1273058 [details] Write Host/Cluster/Datacenter ids to console.vv Description of problem: remote-viewer has the ability of changing the CD that is attached to the virtual machine without the need to access the webpage to do so. It does it by issuing some REST calls with the information provided by the console.vv file, which is downloaded by the browser. Currently this file only contains information about the virtual machine, and to access the correct storage domain for the VM/Datacenter, we need a few REST calls to get to the correct object: 1) Fetch VM with id provided in console.vv, then read Cluser/Host ids 2) Fetch Host with id from VM, then read Cluster Id 3) Fetch Cluster with id from Host, then read Data Center Id 4) Fetch Storage Domains Ids from Data Center, with ISO type 5) Fetch files from Storage domains filtered This process could be eased and much faster if the console.vv file provided the ids for Host/Cluster/DataCenter of the VM. Actually we are most interested in the data center ID, and other information would be provided basically for the sake of completeness. I have worked on a quick patch for writing the info to the console.vv file, but I was not sure about the proper place to set the values. Please take a look at the attached patch. Another idea would be to include the DataCenter id in the VM xml description, but providing all the info in the console.vv file would save another REST call.
We can certainly put anything in the vv file. Though there is another possibility - we're working on REST aggregation which would reduce the number of needed calls as well (bug 1463633). See more discussion in http://lists.ovirt.org/pipermail/devel/2017-March/029954.html
Actually there is a lot of code already done and merged about link following and will land in 4.2. I think using the link following feature is the right approach, thus closing this item for now. Please feel free to reopen if the link following approach will not work for you.

Which REST calls should I submit?

Which REST calls should I submit? the code is not yet merged so the api may change, but it should be as easy as: GET: api/vms?follow=clusters.data_center or something like that.
