Hi Sahina,

I am sorry I can't reproduce the error nor access the logs since I did a fresh installed pn nodes. However now I can't even react that far because the engine deployment fails to start the host up:


[ INFO ] TASK [Wait for the host to be up]

Please help.

Hi,

I am sorry to bother you again. 

I am trying to deploy an oVirt engine for oVirtNode-4.2.5.1. I get the same error I encountered before:

[ INFO  ] TASK [Add glusterfs storage domain]

The glusterd daemon is running.

2018-08-29 16:47:28,846+0200 ERROR (jsonrpc/3) [storage.HSM] Could not connect to storageServer (hsm:2398)

Can you try to see if you are able to mount 172.16.4.18:/engine on the server you're deploying Hosted Engine using "mount -t glusterfs 172.16.4.18:/engine /mnt/test"


During the deployment of the engine it sets the engine entry in the /etc/hosts file with the IP Address of 192.168.124.* which it gets form the virbr0 bridge interface. I stopped the bridge and deleted it, but still giving the same error. Not sure what causes it to use that interface. Please help!

But I give the engine an IP of 192.168.1.10 same subnet as my gateway and my ovirtmgmt bridge. Attached is the ifconfig output of my Node, engine.log and vdsm.log.

Your assistance is always appreciated

There's an error

Please check the volume status using "gluster volume status engine"

and if all looks ok, attach the mount logs from /var/log/glusterfs

Hi,

I have managed to fix the error by enabling the DMA Virtualisation in BIOS. I am now hit with a new error: It's failing to add a glusterfs storage domain:

Hi,

I did not select any CPU architecture. It doenst gove me the option to select one. It only states the number of virtual CPUs and the memory for the engine VM.

Looking at the documentation of installing ovirt-release36.rpm....it does allow you to select te CPU, but not when installing ovirt-release42.rpm

On Tuesday, July 10, 2018, Alastair Neil <ajneil.tech@gmail.com> wrote:
what did you select as your CPU architecture when you created the cluster?  It looks like the VM is trying to use a CPU type of "Custom", how many nodes in your cluster?  I suggest you specify the lowest common denominator of CPU architecture (e.g. Sandybridge) of the nodes as the CPU architecture of the cluster..

Hi,

http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm

This seems to be in the phase where we create a local vm for the engine. We do this with plain virt-install, nothing fancy. Searching the net for "unsupported configuration: CPU mode 'custom'" finds other relevant reports, you might want to check them. You can see the command in bootstrap_local_vm.yml .

Please check/share versions of relevant packages (libvirt*, qemu*, etc) and relevant logs (libvirt).

Also updating the subject line and adding Simone.
