Hi Darrell, Yes , all VMs (both openSUSE and RedHat/CentOS 7) have the ovirt-guest-agent up and running.

Re: Ovirt hiperconverged setup error

Simone has provided you a workaround, so check his e-mail. The ansible is actually running: dig ov-node2 +short As dig is quarrying your DNS server, you need to bypass this check if you use /etc/host entries.

Re: Replace bad Host from a 9 Node hyperconverged setup 4.3.3
by Strahil 12 Jun '19

12 Jun '19

Hi Adrian, You have several options: A) If you have space on another gluster volume (or volumes) or on NFS-based storage, you can migrate all VMs live . Once you do it, the simple way will be to stop and remove the storage domain (from UI) and gluster volume that correspond to the problematic brick. Once gone, you can remove the entry in oVirt for the old host and add the newly built one.Then you can recreate your volume and migrate the data back. B) If you don't have space you have to use a more riskier approach (usually it shouldn't be risky, but I had bad experience in gluster v3): - New server has same IP and hostname: Use command line and run the 'gluster volume reset-brick VOLNAME HOSTNAME:BRICKPATH HOSTNAME:BRICKPATH commit' Replace VOLNAME with your volume name. A more practical example would be: 'gluster volume reset-brick data ovirt3:/gluster_bricks/data/brick ovirt3:/gluster_ ricks/data/brick commit' If it refuses, then you have to cleanup '/gluster_bricks/data' (which should be empty). Also check if the new peer has been probed via 'gluster peer status'.Check the firewall is allowing gluster communication (you can compare it to the firewalls on another gluster host). The automatic healing will kick in 10 minutes (if it succeeds) and will stress the other 2 replicas, so pick your time properly. Note: I'm not recommending you to use the 'force' option in the previous command ... for now :) - The new server has a different IP/hostname: Instead of 'reset-brick' you can use 'replace-brick': It should be like this: gluster volume replace-brick data old-server:/path/to/brick new-server:/new/path/to/brick commit force In both cases check the status via: gluster volume info VOLNAME If your cluster is in production , I really recommend you the first option as it is less risky and the chance for unplanned downtime will be minimal. The 'reset-brick' in your previous e-mail shows that one of the servers is not connected. Check peer status on all servers, if they are less than they should check for network and/or firewall issues. On the new node check if glusterd is enabled and running. In order to debug - you should provide more info like 'gluster volume info' and the peer status from each node.

oVirt engine/engine-setup with other port than default HTTPS 443 possible?
by Dirk Rydvan 12 Jun '19

12 Jun '19

Hello, in a home lab with only one puplic IPv4-Adress is the Port 443 a very precious one. The installation of oVirt 4.3 on a single node/host with bare metal installed CentOS works well. (oVirt Cockpit and local installed engine added after installation of Centos 7.6). But it is more difficult to change the port from 443 to maybe 4443 the save the port 443. The change in: - /etc/httpd/conf/conf.d/ssl.conf - /var/lib/ovirt-engine/jboss_runtime/config/ovirt-engine.xml and - disable selinux - add 4443 to public with firewall-cmd It does not work... now I see is more difficult than I think before... A port redirection at the edge route from <public-IPv4>:4443 to <private-IPv4>:443 does also not work, because the links points all to the standard https adress without a port number. Is there a way to change the default port 443 of oVirt engine to a other port? Many Thanks in advance!

RFE: HostedEngine to use boom by default
by Strahil Nikolov 12 Jun '19

12 Jun '19

Hello All, I have seen a lot of cases where the HostedEngine gets corrupted/broken and beyond repair. I think that BOOM is a good option for our HostedEngine appliances due to the fact that it supports booting from LVM snapshots and thus being able to easily recover after upgrades or other outstanding situations. Sadly, BOOM has 1 drawback - that everything should be under a single snapshot - thus no separation of /var /log or /audit. Do you think that changing the appliance layout is worth it ? Note: I might have an unsupported layout that could cause my confusion.Is your layout a single root LV ? Best Regards,Strahil Nikolov

vNUMA question
by Matthias Leopold 12 Jun '19

12 Jun '19

Hi, when I want to use vNUMA for VMs is it necessary that the number of VM virtual sockets corresponds to the number of vNUMA nodes? concrete example: hypervisor host has 2 physical cpus VM has 2 vNUMA nodes and uses CPU pinning which distributes the VCPUs equally over both physical CPUs is it necessary for the VM to have 2 virtual sockets or is it ok for virtual socket count to be powers of 2 (eg. 16)? thanks matthias

VM Disk Performance metrics?
by Wesley Stewart 11 Jun '19

11 Jun '19

Is there any way to get ovirt disk performance metrics into the web interface? It would be nice to see some type of IOPs data, so we can see which VMs are hitting our data stores the most. It seems you can run virt-top on a host to get some of these metrics, but it would be nice to get some sort of data in the gui. Thanks!
