Stuck on Lab3.2, adding a compute node

Hi, I have followed the steps in LAB_3.2.pdf with a CC already setup as in Lab 2.1. However, after I run the stack.sh in compute node,  there is no issue found, just can't find the compute node in CC node's hyporvisor list, only one record in DB

 

select * from compute_nodes

 

If there anything I should check? How this compute node register itself to CC? Any clue?

 

One comlaint to the Lab environment, it's very difficult to work with, I have to restart all the work everytime pick up the course, either connection issue or something else.

 

Can you provide a working VM? Currently I'm using vagrant / virtualbox to build my own.

    I'm chasing several suspecting issues, like after I ran stack.sh in compute node, there is an error about the generate-subunit, which I didn't notice before:

     

    =========================

    DevStack Component Timing

    =========================

    Total runtime    112

    run_process       15

    apt-get-update    28

    pip_install       31

    wait_for_service   0

    apt-get            2

    =========================

     

    This is your host IP address: 192.168.22.103

    This is your host IPv6 address: ::1

    ./stack.sh: line 501: generate-subunit: command not found

     

    So I checked the install log for the os-testr, which is suppose to provide this command, but suprisingly found that the script uninstalled os-testr-0.7.0 but installed os-testr-0.2.0, what's wrong?

     

    Thanks a lot.

    Thank you Serewicz, I have resolved this problem by executing a git pull / clean / stack again, after get the updated version of devstack now I got the compute node listed.

     

    One change is that the local.conf on compute node, I enabled n-api-meta instead of n-api.

    ENABLED_SERVICES=n-cpu,n-net,n-api-meta,c-vol

    And another difference is that I executed below on the CC node:

    for i in `seq 2 10`; do nova-manage fixed reserve 10.10.128.$i; done

    Not sure if it's related

    And one more difference - 

    I have to execute 

    source openrc admin admin

    on the compute node, otherwise there are errors
