Create standalone tripleo dev setup for multi data center testing

[tzumainn]

@naved001 I accidentally misconfigured the networks in the VM at 172.16.100.201 so that we can't ssh into it anymore; is there a way for me to reset/un-misconfigure it?

[naved001]

do you know which of these hosts is that VM running on?

[centos@kumo-dell-12 ~]$ sudo virsh list
 Id    Name                           State
----------------------------------------------------
 9     ironic-demo                    running
 24    keylime-ironic                 running
 25    keylime-vagrant-ansible-tpm-emulator_keylime1 running
 27    tripleo                        running

or on dell13

 [rado@hypervisor-dell13 ~]$ sudo virsh list
 Id    Name                           State
----------------------------------------------------
 1     ceph2                          running
 3     ceph1                          running
 4     ceph3                          running
 5     ironic                         running

We can look at the console from those then and then configure the networks.

I don't know

[ljmcgann]

tripleo is a promising one. It definitely isnt any of the keylime ones, or ironic-demo

[ljmcgann]

@naved001 can you take a look at the tripleo vm, as it must be that one.

[naved001]

@ljmcgann looks like it's running centos8, do you have the login information?

Also, you could also look at the console if you connect with virt-manager to dell12.

[tzumainn]

@naved001 ah, we were able to access it; then I misconfigured a NIC and now we can't reach it anymore.

virsh console tripleo does not work for me

[naved001]

that may be because the serial console is not configured correctly for that VM.

I meant the VM's "physical" console using virt-manager it connects to remote libvirt and then you can login from the console (or reset the password).

in my SSH config file I have

Host kumo
    User naved
    Hostname kumo-hil-client.infra.massopen.cloud

Host dell12
    User root
    Hostname 172.16.100.121
    ProxyCommand ssh kumo -W %h:%p

This lets me SSH to dell12 (host where the tripleo VM is) by writing ssh dell12. I can then use this same shortcut with virt-manager to connect to libvirt on that host. I choose "Add connection" in virtual machine manager.

And then you can see the physical consoles of those VMs.

what is the password for dell12? I've never been asked for a password for this machine before

[tzumainn]

@naved001 would it be simpler for us to just delete the tripleo vm and create a new one? I'm guessing it's a fairly straightforward process... ? Just want to make sure there aren't any 'gotchas'!

[naved001]

@ljmcgann I added your key from github to the root user. Make sure key is forwarded.

@tzumainn You can certainly create a new VM and also keep this one until you setup the new VM. You would have to figure out the networking (how did it connect to the IPMI network, what was the provisioning VLAN it's using etc).

I would highly recommend trying to get virt-manager working since it'll be useful to debug networking issues in the future too. Being able to see the physical console is really useful.

do you have the login information?

If people don't have the login information, you can try resetting it. Again, this requires access to the physical console of the VM.

[ljmcgann]

i now get asked for login details to standalone-tripleo, which again i wasn't getting before. Im accessing through virt-manager.

[naved001]

@ljmcgann could be more specific? what login details does it ask for when you SSH? and we set the password yesterday so login from the physical console should still work unless someone changed the password.

[ljmcgann]

This is old and from before we went on call yesterday. Everything works as it should, for now

[naved001]

oops, my bad. thanks for the update!

[ljmcgann]

@naved001 I am having issues bringing the centos 8 stream into the moc network. The only file in /etc/sysconfig/network-scripts is ifcfg-ens3, which is mostly empty. There is no bridge device I can connect to it seems?
