Hello,

Any idea about this problem? I don't know if the email got through to the list.

Should I join the #vdsm channel and discuss it there? Is there any other place specific to vdsm where I could report this?

Cheers,

Hi there,

We are trying to setup a node in the same machine where we are running the engine, and noticed that the vdsmd service fails because the supervdsmd daemon can't authenticate against libvirtd afaict.

The error is the following on supervdsmd:

    daemonAdapter[17803]: libvirt: XML-RPC error : authentication failed: authentication failed
    ...

and in libvirtd:

Is there any way to work around that?

We have working infra on top of 4.0 in CentOS 7 systems, and we would like to replicate the exact same environment for availability purposes, in case anything bad happened.

Best regards,
