[ovirt-users] Unable to create a node in oVirt 4.0

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:     Sep 15 03:34:18 ovirt-test libvirtd[17775]: 2020-09-15 07:34:18.410+0000: 17775: error : virNetSocketReadWire:1806 : End of file while reading data: Input/output error     Sep 15 03:34:18 ovirt-test libvirtd[17775]: 2020-09-15 07:34:18.612+0000: 17776: error : virNetSASLSessionListMechanisms:393 : internal error: cannot list SASL mechanisms -4 (SASL(-4): no mechanism available: Internal Error -4 in server.c near line 1757)     Sep 15 03:34:18 ovirt-test libvirtd[17775]: 2020-09-15 07:34:18.612+0000: 17776: error : remoteDispatchAuthSaslInit:3440 : authentication failed: authentication failed     Sep 15 03:34:18 ovirt-test libvirtd[17775]: 2020-09-15 07:34:18.612+0000: 17775: error : virNetSocketReadWire:1806 : End of file while reading data: Input/output error     Sep 15 03:34:18 ovirt-test libvirtd[17775]: 2020-09-15 07:34:18.814+0000: 17778: error : virNetSASLSessionListMechanisms:393 : internal error: cannot list SASL mechanisms -4 (SASL(-4): no mechanism available: Internal Error -4 in server.c near line 1757)     Sep 15 03:34:18 ovirt-test libvirtd[17775]: 2020-09-15 07:34:18.814+0000: 17778: error : remoteDispatchAuthSaslInit:3440 : authentication failed: authentication failed     Sep 15 03:34:18 ovirt-test libvirtd[17775]: 2020-09-15 07:34:18.815+0000: 17775: error : virNetSocketReadWire:1806 : End of file while reading data: Input/output error     Sep 15 03:34:19 ovirt-test libvirtd[17775]: 2020-09-15 07:34:19.017+0000: 17780: error : virNetSASLSessionListMechanisms:393 : internal error: cannot list SASL mechanisms -4 (SASL(-4): no mechanism available: Internal Error -4 in server.c near line 1757)     Sep 15 03:34:19 ovirt-test libvirtd[17775]: 2020-09-15 07:34:19.017+0000: 17780: error : remoteDispatchAuthSaslInit:3440 : authentication failed: authentication failed     Sep 15 03:34:19 ovirt-test libvirtd[17775]: 2020-09-15 07:34:19.020+0000: 17775: error : virNetSocketReadWire:1806 : End of file while reading data: Input/output error 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, -rodri
