<div dir="ltr"><div><div>Hello everyone!<br></div>Currently I want to determine what information is included in messages passing from oVirt engine to VDSM on ovirt-node. <br><br>I
made up a really simple configuration with one VM representing engine,
another - node, a managed to successfully launch a single VM on this
node. However, I have chosen to configure everything automatically.
Currently traffic is encrypted with default certificates. <br></div><div>So, there are three options for me and no one of them really works.<br><br></div><div>1) Find the format of messages ( what the fields are, session id for example) in docs, but I didn't manage to find it;<br></div><div>2)
Use wireshark to decrypt the traffic and the apply maybe a json
-dissector to the decrypted data. I have tried many solutions ( thanks
god I have rsa private and public keys but there is another session key
which is generated every time engine starts to communicate with vdsm,
which I cannot get with the help of sslkeylog file or ld_preload
technology.<br></div><div>Maybe someone knows the exact methodology how to do this correctly?<br><br></div><div>3)
Turn off ssl in oVirt. It is simple to do that for vdsm, but for
engine, according to answers on oVirt site, I should do 2 requests to
the database. I was really surprised that psql was not installed by
oVirt on my system. How did it then created a default database? ( I have
chosen to create all locally and with default configurations). <br></div><div>I mean these two commands : <a href="https://www.ovirt.org/develop/developer-guide/vdsm/connecting-development-vdsm-to-engine/" target="_blank">https://www.ovirt.org/develop/<wbr>developer-guide/vdsm/<wbr>connecting-development-vdsm-<wbr>to-engine/</a> . I have a following error there :<br></div><div>psql: FATAL: Peer authentication failed for user "engine"<br></div><div><br></div><div>Could you please guide my what method is the best and how should I correct my faults there?</div><br></div>
