Hi Aryan,
I downloaded the binary you have mentioned(distributions-base-0.2.0-SNAPSHOT-osgipackage.zip). When I run "./run.sh -virt ovsdb -of13" I get following error "Unknown option -virt". What am I missing ? I am trying to recreate your bug.

Naresh,

Aryan mentioned distributions-virtualization but you are trying distributions-base.

Hi Aryan,
For no error. I used the same controller you have mentioned.(distributions-virtualization-0.2.0-SNAPSHOT-osgipackage.zip). Refer my attachment mytopology.tar.

Changing from critical to normal because, among other things, it appears to be for Hydrogen, not Helium. Ideally we should add a Hydrogen version so we can filter these things out.

This bug is part of the project to Move all ADSAL associated component bugs to ADSAL

Comment by Tony Tkacik [ 05/May/15 ]

Affects now-unsupported Hydrogen. Works on Helium / lithium
