[ovs-discuss] OVN Questions

Hi Darrell,

I checked and it looks similar to your 

+ PATH=/home/mqureshi/ovs/ovn/controller:/home/mqureshi/ovs/ovn/controller-vtep:/home/mqureshi/ovs/ovn/northd:/home/mqureshi/ovs/ovn/utilities:/home/mqureshi/ovs/ovsdb:/home/mqureshi/ovs/vswitchd:/home/mqureshi/ovs/utilities:/home/mqureshi/ovs/vtep:/tools/sw/exa_2.0/exa-tools:/usr/lib64/ccache:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/mqureshi/bin:/sbin
+ export PATH

The difference I see is that in your case, the build directory is "openvswitch/ovs/_gcc" whereas in  my case it is simply "ovs". I have attached the full output of " sh -x ../tutorial/ovs-sandbox --ovn" command.

Have two questions.

1. Do I need to install the openvswitch before installing the ovn-sandbox. I think the sandbox does that for you as I see all the necessary daemons running (ovs-vswitchd, ovsdb-server, ovn-northd, ovn-controller, ovn-controller-vtep)

2. Looks like this sandbox runs its own shell. But "echo $SHELL" still shows "bash" as shell. Is that correct?

mqureshi at vmexa-mqureshi:~/ovs$ echo $SHELL
/bin/bash
mqureshi at vmexa-mqureshi:~/ovs$

3. What if I just wanted to install OVN directly without sandbox, how can I do that (something similar to "sudo apt-get install openvswitch-switch").  Most of the documentation about OVN on Google is about the sandbox. 

Thanks
Maurice

Since the path is not being updated correctly, from build directory (in my case ovs/_gcc), check and show the output of

sh -x ../tutorial/ovs-sandbox --ovn


Output should include something similar to below

.
.
+ PATH=/home/dball/openvswitch/ovs/_gcc/ovn/controller:/home/dball/openv
+ switch/ovs/_gcc/ovn/controller-vtep:/home/dball/openvswitch/ovs/_gcc/o

+ penvswitch/ovs/_gcc/ovsdb:/home/dball/openvswitch/ovs/_gcc/vswitchd:/h
+ ome/dball/openvswitch/ovs/_gcc/utilities:/home/dball/openvswitch/ovs/_
+ gcc/vtep:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
+ export PATH
.
.
