Can you please provide host-deploy logs or maybe a full sos report? Just to understand where this is failing. (Originally by Sandro Bonazzola)
(In reply to Sandro Bonazzola from comment #3) > Can you please provide host-deploy logs or maybe a full sos report? > Just to understand where this is failing. Isn't the host just failing to run those commands in comment #0? I will reproduce it again and attach the logs shortly. (Originally by Germano Veit Michel)
Created attachment 1242036 [details] engine install log There are not really many logs as the failure if very early. It's failing to run this in the host, so the deploy does not even start to generate logs. umask 0077; MYTMP="$(TMPDIR="${OVIRT_TMPDIR}" mktemp -d -t ovirt-XXXXXXXXXX)"; trap "chmod -R u+rwX \"${MYTMP}\" > /dev/null 2>&1; rm -fr \"${MYTMP}\" > /dev/null 2>&1" 0; tar --warning=no-timestamp -C "${MYTMP}" -x && "${MYTMP}"/ovirt-host-deploy DIALOG/dialect=str:machine DIALOG/customization=bool:True with: Read-only file system: 'os.devnull'. https://docs.python.org/3/library/os.html#os.devnull So is it complaining that /dev/null is read-only? Doesn't make much sense to me. (Originally by Germano Veit Michel)
Simone, can you please check in this is related to bug #1414265 (Originally by Sandro Bonazzola)
I tried adding an host deployed with rhev-hypervisor7-7.2-20160920.1 on an engine 4.1 on a cluster with cl=3.6 and it failed due to: 2017-02-02 16:07:22 DEBUG otopi.context context._executeMethod:142 method exception Traceback (most recent call last): File "/tmp/ovirt-71Zg8vz4ZC/pythonlib/otopi/context.py", line 132, in _executeMethod method['method']() File "/tmp/ovirt-71Zg8vz4ZC/otopi-plugins/otopi/core/transaction.py", line 93, in _main_end self._mainTransaction.commit() File "/tmp/ovirt-71Zg8vz4ZC/pythonlib/otopi/transaction.py", line 148, in commit element.commit() File "/tmp/ovirt-71Zg8vz4ZC/otopi-plugins/ovirt-host-deploy/kernel/kernel.py", line 80, in commit self._parent._build_grubby_command(), File "/tmp/ovirt-71Zg8vz4ZC/pythonlib/otopi/plugin.py", line 931, in execute command=args[0], RuntimeError: Command '/sbin/grubby' failed to execute 2017-02-02 16:07:22 ERROR otopi.context context._executeMethod:151 Failed to execute stage 'Transaction commit': Command '/sbin/grubby' failed to execute (Originally by Simone Tiraboschi)

Once we fix that, the engine is able to add the host but if fails configuring the management bridge.
