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

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,

I have just re-installed centOS 7 in 3 servers and have configured gluster volumes following this documentation: https://www.ovirt.org/blog/2016/03/up-and-running-with-ovirt-3-6/, But I have installed

​package. Hosted-engine --deploy is failing with this error:

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. Best regards, -- Didi
