CPU Type compatibility matrix
by Gianluca Cecchi 11 Dec '19

11 Dec '19

Hello, In my case I currently have a cluster with hosts with cpu Intel E5-2680 v4 (each socket with 14 cores) and their Cluster is set as "Intel Broadwell Family" and I would like to add in the same oVirt Cluster two more hosts with Intel E5-2640 v4 cpus (each socket 10 cores) that should be the same CPU Family Type. Is it true? Is there a sort of matrix where one could compare and match? Thanks in advance, Gianluca

Re: Clusters: Clarification needed on the ballooning memory feature and its affects on the physical hosts memory
by donagh.moran＠oracle.com 11 Dec '19

11 Dec '19

Hi Paul Thanks for the info, you makes it clear what each memory attribute represents in Ovirt but I'm still a little unclear how I would generate over 80% memory usage on the host. Shared Memory: 0% The Max free Memory for scheduling new VMs is 7978 MB which makes sense as its roughly the reminder of 200% of the total host memory minus the memory size allocated for the 4 VM's

katello-host-tools-3.5.1 and Red Hat Satellite 6.4
by Matthias Leopold 11 Dec '19

11 Dec '19

Hi, I'm trying to register hosts running CentOS 7.6 and oVirt 4.3.5 to a Red Hat Satellite 6.4 server. The oVirt hosts have katello-host-tools-3.5.1 packages from oVirt repos, which seem to be too new for the Red Hat Satellite 6.4 server, Satellite says: Errata: Could not calculate errata status, ensure host is registered and the katello-host-tools package is installed Is there a way to get around this? Downgrade katello-host-tools? -> is this OK for oVirt? Upgrade Red Hat Satellite? -> server not under my control... Is there a compatibility matrix for katello-host-tools and Red Hat Satellite versions? I'm new to this topic.... thx Matthias

unable to connect to the graphic server console.vv
by Pradeep Danthi 11 Dec '19

11 Dec '19

Dear Ovirt Team, Kindly help with this issues that I am facing in my Redhat Virtualization servers. I am unable to access my VM through console, I am getting this error when I right click and try connecting console. My observation is, this is happening after renewing the self-signed ssl certificate in all the nodes as nodes were non responsive before renewing the ssl lcertificate. Kindly help as we are unable to access the VMs through console (console.vv) Regards, Pradip 9900056579 ________________________________ This email was scanned by Bitdefender

Hi Pavel, Can you explain how did you find the issue. I'm new in OVN and I experience the same symptoms . I'm not sure what will be the best approach to start cleanly with OVN.

Hi All, It seems that I have several devices listed in 'ovs-vsctl list interface' despite removing all networks except ovirtmgmt. Can someone tell me which devices I should leave (so I can remove the rest) ? Thanks in advance.
