Hi,
in a new deployed host (Centos8, oVirt 4.4) with python module ovirt-engine-sdk-python
4.4.15 I was unable to use the Python SDK API. The script hanged in the connection test,
with the following strace:
....
futex(0x7fc03e47a9e8, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 0,
{tv_sec=1629103636, tv_nsec=938478000}, FUTEX_BITSET_MATCH_ANY) = -1 ETIMEDOUT (Connection
timed out)
futex(0x7fc03e47aa40, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x7fc03e47a9e8, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 0,
{tv_sec=1629103636, tv_nsec=943557000}, FUTEX_BITSET_MATCH_ANY) = -1 ETIMEDOUT (Connection
timed out)
futex(0x7fc03e47aa40, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x7fc03e47a9e8, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 0,
{tv_sec=1629103636, tv_nsec=948631000}, FUTEX_BITSET_MATCH_ANY) = -1 ETIMEDOUT (Connection
timed out)
futex(0x7fc03e47aa40, FUTEX_WAKE_PRIVATE, 1) = 0
...
API via a simple curl worked fine, in another host (still Centos8, oVirt 4.4) with the
module version 4.4.14 everything works fine. Downgrading the python module from 4.4.15 to
4.4.14 via pip3 fixed the problem.
What could be the problem and it could be related to the recent branches split (I doubt
but...).
Regards,
Francesco

Which script?
What was the output of the script?
Most scripts log to example.log, do you have any clue there?
Some scripts support --debug option to log more info to the log. Did you use it?
If you run strace, use:
strace -f -tt -T -o output.strace command ...
And share the complete trace.
This will show all threads/child processes and add timestamps and syscalls
elapsed times.

Hi Francesco,
any reason why you are installing Python SDK on the host from pip when
there is an RPM available? Could you please try to remove pip installed
version and use RPM installed and retest?
Thanks,
Martin

Hi Martin,
I didn't encounter the error anymore on any further deployed host so I
guess it was an isolated problem with Python.
Anyway, not any "real" reason, both RPM and python module are
installed on the host. The install is performed via Ansible, a lot of
hands writing the code so...
rpm -qa | grep sdk
python3-ovirt-engine-sdk4-4.4.13-1.el8.x86_64
pip3 list | grep sdk
ovirt-engine-sdk-python (4.4.14)
Should I use only the RPM and remove the Python module?
Thanks also to @Nir for your time.
Regards,
Francesco
