Can not login to the compute-host from the devstack-cc node. I verified the network and eth2 has an IP of 192.168.97.1

I can sucessfully get into the Horizon dashboard using the public IP on eth0

I tried to ping compute-host by name and by IP and it does not work

Has anyone else had this issue?

Thanks !!

    Hello,

    Instead of compute-host, try compute-node, or ip via 192.168.97.2.

    Best regards,

    Tried that before and just tried again.

    I get "no route to host" also a ping does not work either. Maybe it might be better to just start over as maybe there is a network issue with this host.

    Thanks

    Yes, please use the Start over button.  It sounds like the network is off for some reason. I spun up a new lab, just now, and was able to ping/ssh to compute-node. Hopefully it is a transient issue, not infrastructure.  

    If problem persists, please let us know.

    I completely rebuilt (I went from work to home and I had to wait for the envirnment to rebuild) and again same issue. 

    Some info:

    ubuntu@devstack-cc:~/devstack$ ip addr show eth2

    4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

        link/ether bc:76:4e:02:c6:2b brd ff:ff:ff:ff:ff:ff

        inet 192.168.97.1/24 brd 192.168.97.255 scope global eth2

           valid_lft forever preferred_lft forever

        inet6 fe80::be76:4eff:fe02:c62b/64 scope link

           valid_lft forever preferred_lft forever

    ubuntu@devstack-cc:~/devstack$ ssh compute-node

    ssh: connect to host compute-node port 22: No route to host

    ubuntu@devstack-cc:~/devstack$ ping 192.168.97.2

    Thank you for the output of the ip a command. I just logged into a new lab and if you are starting lab 3.2, the ip address hould be found under br100. 

    Just to be sure. When  you open lab 3.2 - before doing anything  - the 192.168.97.1 IP is under eth2 and you cannot ssh to compute-node. I'm trying to narrow down if it is an configuration step, or a deployment issue. 

    I will contact internal support to dig into what could be causing this.  This is what I see, immediatly after loggin in:


    ubuntu@devstack-cc:~/devstack$ ip addr show br100
6: br100: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default

    inet 10.10.129.255/20 brd 10.10.143.255 scope global br100
       valid_lft forever preferred_lft forever
    inet 192.168.97.1/24 brd 192.168.97.255 scope global br100
       valid_lft forever preferred_lft forever
    inet6 fe80::68e4:9ff:fe4e:f7e6/64 scope link
       valid_lft forever preferred_lft forever
ubuntu@devstack-cc:~/devstack$ ssh compute-node

    As I look at lab 2, I note it matches the network setup you are seeing as well. The compute-node has not been added to the lab environment in lab 2. If you read the intro to the labs you'll find it mentions how each lab is seperate, and not capable of running in a contingous manner. 

    Please double check which lab you are starting, verify this is the lab environment you are seeing when you start with lab 3.2

    Glad that the process worked. If you revisit the lab and continue to have issues, please feel free to contact us.
