Get VMs assigned to user via API

Latest response

I'm currently evaluating RHEV solution, and I would like to write some script for the user. Part of this script - is to get info about VMs assigned to him. 

How could it be possibly done? I'm able to get full list of VMs - but only when usnig API with admin permissions. Is it possible to run API with user permissions?

I am somewhat familiar with 2 options available via the RESTapi - Curl and Python.  I found curl to be a much easier option for me personally as I am not very proficient with python.  The RESTapi guide has not yet been updated to 3.1 (that I have seen) so, check for the doc under 3.0 - the doc is actually very helpful in providing the foundation to get started quickly.

https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Virtualization/3.0/html-single/REST_API_Guide/index.html

Check out section 2.1 on how to retrieve the cert from your RHEV manager.

Here is their example

curl -X GET -H "Accept: application/xml" -u [USER:PASS] --cacert [CERT] https://[RHEVM Host]:8443/api

 

and this is what I typically run and then parse out:

curl -k -X GET -u "${USERNAME}@${DOMAIN}:${PASSWORD}"--cacert rhevm.cer -H "Accept: application/xml" https://${RHEVM}/api/vm

curl -k -X GET -u "${USERNAME}@${DOMAIN}:${PASSWORD}" -H "Accept: application/xml" https://${RHEVM}/api/vms?search=servername

James, thank you for your comment. I'm familiar with RESTful API and the way of using curl with it. The actual problem I faced - is that I cannot run API request where username has just UserRole permission assigned. In this case I get responce 

"query execution failed due to insufficient permissions"

 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<fault>
    <reason>Operation Failed</reason>
    <detail>query execution failed due to insufficient permissions.</detail>
</fault>

 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<fault>
    <reason>Operation Failed</reason>
    <detail>query execution failed due to insufficient permissions.</detail>
</fault>

Dmitry,

This curl command should return a list of VMs assigned to a non-admin user:

curl --cacert $CACERT -u "$USER:$PASSWORD" -H "Accept: application/xml" -H "Filter: true" -X GET https://$RHEVM_HOST/api/vms

Also, the API documentation for 3.1 is in the Developer Guide:

Thank you very much! This was exactly what I was looking for - your advice worked. 

My fault, I didn't notice the functionality of "Filter" header in request.

Thanks Anthony!  I see the word Developer and I automatically look the other way ;-)  I figured either the API hadn't changed for 3.1, or the RESTapi doc would be released later.  I'm glad you pointed out it's now in the Developer Guide.
