Re: 3node HCI fails when HostedEngineLocal is trying to add additional Gluster members

by Strahil

Most probably the vdsm or supervdsm's PreExec task is doing it (they got multiple, so you can run manually till you find it out). Just try the following: systemctl stop vdsmd supervdsmd systemctl start supervdsmd Check for certs systemctl start vdsmd Keep in mind that that the chain of events (at least for me is): 1. VG activation 2. VDO activation 3. Gluster brick is mounted (I use systemd service due to deps between vdo, gluster brick and glusterd) 4. Glusterd and libvirt are started 5. Sanlock is started 6. Supervdsm 7. Vdsm If this is a host that will host HostedEngine VM: 8. Ovirt-ha-broker 9. Ovirt-ha-agent After cleanup, did you reboot?

CPU Type compatibility matrix

by Gianluca Cecchi

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

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

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

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
