VMs unknown state and ovirt node Non Responsive
Hi. I have a simillar problem like in this link: https://access.redhat.com/discussions/1326793 https://bugzilla.redhat.com/show_bug.cgi?id=1165269 Similar, becouse I worked it out with the VM uknown status, but I still have problem with host (node). It is all in one installaltion, therefore i dont have to remove host and add again (it is only one host portal and node on the same host), because there are still connected to the VMs. It is ovirt 3.4.4 release in latest updates on Centos 6.6 (Centos 6.5 Final). Can I do smoethings or can I upgrade to ovirt 3.5 release (safely without losing anything) if this helps. If anyone would like to help me remotely (for charity), I would be grateful :) -- G.Sz.

If your problem is related to that link, then you should have tried to downgrade the JDK, and it should have worked. To double check you can check the /usr/lib/jvm/java-1.7.0-openjdk-*/jre/lib/security/java.security file. It may contain this line, at the very end: jdk.tls.disabledAlgorithms=SSLv3 That is because of the recent security problems with SSLv3. If you need to solve your problem urgently and you are sure that you won't be affected by those security problems then you can just comment out this line and restart the engine. Remember to undo this change once you upgrade to 3.5. -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif. Gorbea 3, planta 3ºD, 28016 Madrid, Spain Inscrita en el Reg.

The actual problem is that there is no way to tell the oVirt engine to use a protocol other than SSLv3 to communicate with hosts. That has been fixed in version 3.5: http://gerrit.ovirt.org/34917 Given that this is an important security issue I'd expect to see it fixed in 3.4.z as well. While/if that doesn't happen then your only alternative to fix properly the issue is to upgrade to 3.5 and then make sure that the VdsmSSLProtocol configuration parameter is set to TLSv1.
