Hi,<br>I installed a new node running oVirt Node 2.5.5 and I couldn&#39;t start a VM using SPICE. The error was about the SPICE couldn&#39;t use the CA certificate. I started looking on the /etc/pki directory on the node and found that the /etc/pki/vdsm/libvirt-spice/ca-cert.pem was blank. I copied the /etc/pki/vdsm/certs/cacert.pem to it and it worked. There is another post about this issue: &quot;[Users] Cannot connect to guest with spice console;    SSL validate error&quot;.<br>
Is this an issue concerned to the activate command when the node is registered on the manager?<br><br>Alexandre<br>
