So I suppose it failed after 3605 seconds, or 721 attempts (of 5 seconds each).
Do you see the VM in 'virsh list'?
Can you see the VM running (e.g. 'ps auxww | grep qemu')?
Can you try to ssh to it from the host (search the logs for
local_vm_ip for its local/private temporary address)?
Perhaps open its console (Perhaps 'virsh console HostedEngineLocal')?
That said, I'd personally also consider it a bug in ansible, unless
you made some relevant custom changes - the bug is that it seems to
leak open files.
Thanks and best regards,
