Hi,
I checked the symlinks and it was broken in mine too. I have manually changed them to point to python2.7.
localhost in
/usr/share/ovirt-host-deploy/interface-3/pythonlib ○ → ls -l
total 4
lrwxrwxrwx. 1 root root 45 Jun 24 15:29 otopi ->
../../../../lib/python3.6/site-packages/otopi
lrwxrwxrwx. 1 root root 60 Jul 12 16:34 ovirt_host_deploy ->
../../../../../lib/python2.7/site-packages/ovirt_host_deploy
lrwxrwxrwx. 1 root root 58 Jul 12 16:34 ovirt_host_mgmt ->
../../../../../lib/python2.7/site-packages/ovirt_host_mgmt
Now when I am trying to run bin/engine-setup. It is giving the following error
bin/engine-setup
***L:ERROR Internal error: No module named 'M2Crypto'
Also tried the following:
1.install python3.6 . setup in alternatives
2. installed ovirt python 3.6 dependecies
(otopi,ovirt_host_deploy,ovirt_host_mgmt)
3.Fixed symlinks
4. Tried running bin/engine-setup
Giving the error as:
bin/engine-setup
***L:ERROR Internal error: No module named 'M2Crypto'

Perhaps you need them on the engine machine. Didn't check, but it makes sense. Please try, on the engine machine: 1. Install all relevant python2 packages (otopi, ovirt-host-deploy, ?) 2. rm /var/cache/ovirt-engine/ovirt-host-deploy.tar 3. Then try to add the hostThanks, Yuval.

No idea why exactly, I still didn't try that myself. Please check: ls -l /usr/share/ovirt-host-deploy/interface-3/pythonlib Both before and after installing python2 packages as suggested above. Now tried these on an fc28 machine, and I get: [pythonlib]# ls -l total 0 lrwxrwxrwx. 1 root root 45 Jun 24 12:59 otopi -> ../../../../lib/python3.6/site-packages/otopi lrwxrwxrwx. 1 root root 57 Jun 24 12:59 ovirt_host_deploy -> ../../../../lib/python3.6/site-packages/ovirt_host_deploy lrwxrwxrwx. 1 root root 55 Jun 24 12:59 ovirt_host_mgmt -> ../../../../lib/python3.6/site-packages/ovirt_host_mgmt [pythonlib]# rpm -qf * ovirt-host-deploy-common-1.8.0-0.0.master.20180624095611.git827d6d1.fc28.noarch ovirt-host-deploy-common-1.8.0-0.0.master.20180624095611.git827d6d1.fc28.noarch ovirt-host-deploy-common-1.8.0-0.0.master.20180624095611.git827d6d1.fc28.noarch Where the two latter links are dead. This is because I did only 'dnf install ovirt-engine', which does not carry (for now) python3-ovirt-host-deploy. It seems (mainly thinking out loud, also adding Yuval) that this is the process: 1. You install either py2 or py3 otopi+host-deploy on the engine (or both) 2. The engine creates an otopi bundle: 2.1. It copies the plugins from the common path/pkg, which is always installed. 2.2. It copies the library files from the python lib of the python that otopi chose to run, on the _engine_. If you have python3, it will be python3 files. If 2, 2. In your case, you ran 3, but (perhaps?) pythonlib is empty, need to check why. 2.3. So the bundle contains python-version-specific files in pythonlib, but this in theory should not be a big concern: 3. Engine copies the bundle to the host, untars, and runs. 4. If on the host otopi chooses a different python than the one used to create the bundle, pythonlib will include wrong binary (.pyc/.pyo) files (at least in wrong locations), but the text/source files should still be available, if all goes well. Yuval - does this sound like the plan we (vaguely) had? (Kaustav - please "reply all" - it's much easier to follow a conversation this way. Thanks) Also, perhaps open a bug about this. Still not sure what's the best option. Some I can think of: 1. Just ignore this case. Assume that engine and host machines use same python, and developers that want to test something else will need to install the relevant other packages. 2. Make the engine require both py2 and py3 packages. Not sure this makes much sense, need to think about it. We also need to continue support the engine on el7, where we do not have py3 by default (and probably do not want to install it). So perhaps do this only on fedora. 3. Something else? E.g. check for any available python and use that? That's not very easy for now, as the above links are packaged, meaning created during building/packaging time, not run time, so then we still do not know which python will actually be available.On Wednesday 11 July 2018 06:30 PM, Kaustav Majumder wrote: Hi, The output of sh -x otopi --> https://pastebin.com/WeeCJYdk tar in the attachment On Wednesday 11 July 2018 06:14 PM, Yedidyah Bar David wrote: On Wed, Jul 11, 2018 at 10:21 AM, Kaustav Majumder <kmajumde@redhat.com> wrote:Hi, Following are the versions otopi-1.8.0-0.0.master.20180704073752.git9eed7fe.fc28 ovirt-host-deploy-common-1.8.0-0.0.master.20180624095611.git827d6d1.fc28.noarch python2-ovirt-host-deploy-1.8.0-0.0.master.20180624095611.git827d6d1.fc28.noarch I copied the tar to the host and when I am trying to install its giving the following error [root@dhcp43-133 ~]# ./ovirt-host-deploy ***L:ERROR: Python is required but missingCan you please try running, from the same directory on the host, 'sh -x otopi' ?
