Hi,

I checked the symlinks and it was broken in mine too. I have manually changed them to point to python2.7.

Did you try installing python2-ovirt-host-deploy?

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 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'

I do not follow. It worked for you in the past? What changed since then?

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'

Hi,

I installed python2-otopi rpm in the host and then when I try to add host it gives the following error--> An error has occurred during installation of Host 10.70.43.129: Internal error: No module named ovirt_host_deploy.

I  am getting the same error when I manually copy the tar and run in the host.

Am I missing some dependencies in my dev env?

It looks like you don't have python3 installed, so otopi falls back to /bin/python which is python2, but the python2 otopi module is not installed - try to install the python2-otopi rpm and see if it works for you.

This should not be needed on the _host_.

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 host

Thanks,
Yuval.

Hi,

'pythonlib' directory is empty.Is it something to do with that?

Yes, that's the problem. 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:

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.

Can you please try running, from the same directory on the host, 'sh -x otopi' ?

Also, can you please share the bundle tar file?

Do you want to use fedora 28 specifically? Or just get a dev env working? If latter, it's currently easier to use el7.

I have tried installing it several times and it has failed.

Which versions of otopi and ovirt-host-deploy do you have?

Can you install otopi on the host and run it? Does it work?

You can also try copying and running the host-deploy bundle manually to the host. It's on the engine machine in /var/cache/ovirt-engine. Copy it to the host, untar in some directory, and run from inside it:

$PWD/ovirt-host-deploy
