Bug 1635532

Description of problem:

python-virtualbmc doesn't work after installation from RHOSP14 repositories.

How reproducible:

Always.

Steps to Reproduce:

# sudo yum localinstall -y http://download.lab.bos.redhat.com/rcm-guest/puddles/OpenStack/rhos-release/rhos-release-latest.noarch.rpm
# rhos-release -P 14
# yum install python2-virtualbmc-1.4.0
# systemctl enable virtualbmc
# systemctl start virtualbmc

Actual results:
# systemctl status virtualbmc
● virtualbmc.service - Virtual Baseboard Management Controller Emulation service
   Loaded: loaded (/usr/lib/systemd/system/virtualbmc.service; enabled; vendor preset: disabled)
   Active: failed (Result: start-limit) since Wed 2018-10-03 09:46:20 CEST; 176ms ago

vbmcd is not functioning

Expected results:

vbmcd is up and running

Additional info:

When you run vbmcd manually you'll get

#/usr/bin/vbmcd --foreground
Traceback (most recent call last):
  File "/usr/bin/vbmcd", line 6, in <module>
    from virtualbmc.cmd.vbmcd import main
  File "/usr/lib/python2.7/site-packages/virtualbmc/cmd/vbmcd.py", line 22, in <module>
    from virtualbmc import control
  File "/usr/lib/python2.7/site-packages/virtualbmc/control.py", line 20, in <module>
    import zmq
ImportError: No module named zmq

so python2-virtualbmc-1.4.0 doesn't have python-zmq as dependency in package definition. Also, python-zmq as well as zeromq are not present in RHOSP repositories.

To workaround the problem operator may do the following:
# yum localinstall http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# yum install python-zmq zeromq

Then vbmcd starts working as expected

# systemctl start virtualbmc
# systemctl status virtualbmc
