Issue deploying self hosted engine on new install
by Robert Webb 06 Dec '19

06 Dec '19

Hi all, I am trying to deploy the self hosted engine via cockpit and it is failing at the very end of deployment when it is checking the VM Health. I have done multiple clean installs and run this and it fails every time. I have also tried from the cli via ssh with the same outcome. After the failure, if I look at the oVirt Machines section of the node, the VM is there but will not start. Anyone else having this issue?

Gluster FS & hosted engine fails to set up
by rob.downer＠orbitalsystems.co.uk 05 Dec '19

05 Dec '19

I have set up 3 new servers and as you can see Gluster is working well, however the hosted engine deployment fails can anyone suggest a reason ? I have wiped and set up all three servers again and set up Gluster first. This is the gluster congig I have used for the setup. Please review the configuration. Once you click the 'Finish Deployment' button, the management VM will be transferred to the configured storage and the configuration of your hosted engine cluster will be finalized. You will be able to use your hosted engine once this step finishes. * StorageStorage Type:glusterfs Storage Domain Connection:gfs3.gluster.private:/engine Mount Options:backup-volfile-servers=gfs2.gluster.private:gfs1.gluster.private Disk Size (GiB):58 [ INFO ] TASK [ovirt.hosted_engine_setup : Add glusterfs storage domain] [ ERROR ] Error: Fault reason is "Operation Failed".

Possible sources of cpu steal and countermeasures
by klaasdemter＠gmail.com 05 Dec '19

05 Dec '19

Hi, I'm having performance issues with a ovirt installation. It is showing high steal (5-10%) for a cpu intensive VM. The hypervisor however has more than 65% of his resources idle while the steal is seen inside of the VM. Even when placing only a single VM on a hypervisor it still receives steal (0-2%), even though the hypervisor is not overcommited. Hypervisor: 2 Socket system in total 2*28(56HT) cores VM: 30vCPUs (ovirt seems to think its a good idea to make that 15 sockets * 2 cores) My questions are: a) Could it be that the hypervisor is trying to schedule all 30 cores on a single numa node, ie using the HT cores instead of "real" ones and this shows up as steal? b) Do I need to make VMs this big numa-aware and spread the vm over both numa nodes? c) Would using the High Performance VM type help in this kind of situation? d) General advise: how do I reduce steal in an environment where the hypervisor has idle resources Any advise would be appreciated. Greetings Klaas

Hi, I want to use External Logical Networks Openstack Neutron. For this it is necessary to have all Openstack installed or is it possible to have only Neutron and used as a service? Sorry if the question is very obvious but I am starting now with this topic.

Re: 3node HCI fails when HostedEngineLocal is trying to add additional Gluster members
by Strahil 04 Dec '19

If you manage to get your VM on the gluster - you are almost done. I had similar situation and using virsh/hosted-engine , I have managed to reach the GUI. From there we can have a Clue what is going on. Usually there is a dependency: - Master storage domain should be UP -This allows the DC to become UP -Then a host in the cluster can become SPM (control storage) -And only then you can start your other gluster volumes. So I can only recommend you to try to reach GUI and check the situation. Then it will be moderately easy to bring everything up.
