Hello Anton, if your organisation has it's own CA you can install your own certificates or get certificates from a trusted CA. https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL.html Paul S. ________________________________ From: Anton Louw via Users <users(a)ovirt.org> Sent: 12 June 2020 08:56 To: users(a)ovirt.org <users(a)ovirt.org> Subject: [ovirt-users] oVirt noVNC Caution External Mail: Do not click any links or open any attachments unless you trust the sender and know that the content is safe.

PKIX path error

by Stack Korora

Greetings, I have a running oVirt install that's been working for almost 2 years. I'm building a _completely_ new install. I mention it because it is useful for me to compare configurations when I run into issues like this one. Right now there are three physical hosts: 1x management where I run the engine and db 2x hypervisor nodes. I had it up and installed and running smooth this morning on 4.3.9.4-1.el7 on Scientific Linux 7.8 (fully patched). I copied over our 3rd party certs from the running system and restarted httpd. Perfect. SSL is running! /etc/pki/ovirt-engine/apache-ca.pem /etc/pki/ovirt-engine/certs/apache.cer /etc/pki/ovirt-engine/keys/apache.key.nopass Next I used ovirt-engine-extension-aaa-ldap-setup to point to our ldap server. I did the login and search test and both passed on the command line! Horray! Then I went to the web interface... sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I'm digging through logs and I don't see anything close to this error except nearly the identical message in engine.log. ERROR [org.ovirt.engine.core.aaa.servlet.SslPostLoginServlet] (default task-2) [] server_error: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I can't log in via the web at all, I only get that message (so I can't even test out the local admin). The aaa ldap configuration it generated is darn near perfectly identical (just a name change). The certs are the same. Even when I look in the keystore, the sha1 hashes are the same between the two environments! After over an hour poking at this, I'm completely stumped. Can someone please give me a pointer on what I should try next? Thanks! ~Stack~

Gluster remount?

by Christoph Köhler

Hey, it happens in our ovirt 4.3.9 occasionally that after reboot one of the dedicated gluster nodes (replica3, arbiter 1) some client connections are missing on server side: # gluster volume status gluvol3 clients Client connections for volume gluvol3 ---------------------------------------------- Brick : glusrv01:/gluster/p1/brick1 Clients connected : 17 Hostname . . . -------------------------------------------- Brick : glusrv02:/gluster/p1/brick1 Clients connected : 15 <---- two connections missing Hostname . . . ---------------------------------------------- Brick : glusrv03:/gluster/p1/brick1 Clients connected : 17 Hostname . . . ---------------------------------------------- I don't know why it happes, the log files don't really help. Now: is there a possibility on the missing nodes to reinitiate the gluster mount like 'mount -o remount' or so? The only way I actually know is to set the concerned node to maintenance and reactivate it. But that is really long-moving with many VMs... Any ideas? Thanks Chris

Some of the features included in oVirt 4.4.1 Release Candidate require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2.

What happens when shared storage is down?

by Vinícius Ferrão

Hello, This is a pretty vague and difficult question to answer. But what happens if the shared storage holding the VMs is down or unavailable for a period of time? I’m aware that a longer timeout may put the VMs on pause state, but how this is handled? Is it a time limit? Requests limit? Who manages this? In an event of self recovery of the storage backend what happens next? Manual intervention is required? The VMs may be down or they just continue to run? It depends on the guest OS running like in XenServer where different scenarios may happen? I’ve looked here: https://www.ovirt.org/documentation/admin-guide/chap-Storage.html but there’s nothing that goes about this question. Thanks, Sent from my iPhone
