Description Lucie Leistnerova 2018-05-11 12:30:31 UTC

Description of problem:
Getting link href for reporteddevices by VM's NIC doesn't return anything even when it should.

Version-Release number of selected component (if applicable):
ovirt-engine-restapi-4.2.3.5-0.1.el7.noarch

How reproducible: always


Steps to Reproduce:
1. create new VM with default parameters in engine
2. install OS and guest agent on the VM
3. in webadmin you can see some info in VM detail -> Network interfaces -> nic1 -> Guest Agent Data
3. get nic1 id for that VM, e.g. from
curl -k -u admin@internal:xxx -H "Prefer: persistent-auth" https://engine/ovirt-engine/api/vms/<vm_id>/nics
3. get reported devices from links by that NIC, e.g.
curl -k -u admin@internal:xxx -H "Prefer: persistent-auth" https://engine/ovirt-engine/api/vms/<vm_id>/nics/<nic_id>/reporteddevices

Actual results: no devices
    <reported_devices/>


Expected results: some device e.g.
    <reported_devices>
        <reported_device href="/ovirt-engine/api/vms/735917b1-e057-4265-bdc5-c8cb98eb1930/reporteddevices/65746830-3030-3a31-613a-34343a30383a" id="65746830-3030-3a31-613a-34343a30383a">
            <name>eth0</name>
            <description>guest reported data</description>
            <ips>
                <ip>
                    <address>...</address>
                    <version>v4</version>
                </ip>
                <ip>
                    <address>...</address>
                    <version>v6</version>
                </ip>
            </ips>
            <mac>
                <address>...</address>
            </mac>
            <type>network</type>
        </reported_device>
    </reported_devices>

or the link should be removed, because reported_devices is printed already by the NIC

Comment 1 Ori Liel 2018-05-30 08:15:15 UTC

The bug does not reproduce for me. 

I've reproduced the scenario: created a VM, installed an OS on it, installed and ran the guest-agent, then queried for the VM's nic, and inside it followed the link to the reported-devices. 

The result of the query contained the expected 'guest reported data'.

I've closed the bug, please re-open if necessary with more precise steps to reproduce

Comment 2 Lucie Leistnerova 2018-05-30 09:02:34 UTC

There are two links to reported devices by the vnic

<name>nic1</name>
...
<link href="/ovirt-engine/api/vms/ee8fd101-7bf7-4f8f-a8b5-774c78f039ce/nics/0e3f7916-b2b2-42c5-90ad-32907cdc1292/reporteddevices" rel="reporteddevices"/>
...
<reported_devices>
<reported_device href="/ovirt-engine/api/vms/ee8fd101-7bf7-4f8f-a8b5-774c78f039ce/reporteddevices/65746830-3030-3a31-613a-34613a31363a" id="65746830-3030-3a31-613a-34613a31363a">

and the first one (that goes to nics->devices) doesn't show anything. 
Second that goes to exact device with vms->devices works fine.

Comment 3 Radim Hrazdil 2018-07-09 11:20:19 UTC

Verified that query for reporteddevices returns following structure:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<reported_devices>
    <reported_device href="/ovirt-engine/api/vms/<vm_id>/reporteddevices/<nic_id>" id="<nic_id>">
        <name>eth0</name>
        <description>guest reported data</description>
        <ips>
            <ip>
                <address><ip></address>
                <version>v4</version>
            </ip>

        </ips>
        <mac>
            <address><mac_addr></address>
        </mac>
        <type>network</type>
        <vm href="/ovirt-engine/api/vms/<vm_id>" id="<vm_id>"/>
    </reported_device>
</reported_devices>
