openstack command fails with SSL error on Ubunut 18.04 LTS

Openstack client commands fails after sourcing the rc file in Ubuntu 18.04 LTS with below error message; I tried the same operation in CentOS and it went well there. I am surprised why in Ubuntu 18.04 LTS it is failing.

  ubuntu@clover:~$ openstack image list

openstack – How do I perform a release upgrade on a server running Landscape?

I’m attempting to perform a release upgrade from 18.04LTS to 20.04LTS, on my server running Landscape.

The upgrade is blocked due to

An unresolvable problem occurred while calculating the upgrade.
This was likely caused by:
* Unofficial software packages not provided by Ubuntu

According to the upgrade log, the unofficial software is the landscape server (if I’m interpreting “Foreign” correctly):

2020-11-18 19:17:24,416 DEBUG Foreign: landscape-client landscape-common landscape-hashids landscape-server landscape-se
rver-quickstart libjs-yui3-common libjs-yui3-full libjs-yui3-min python-convoy python-pyjwkest python-pyoidc python-stor
m python-stripe python-talisker python-txamqp python-txaws python-txjuju python-txlongpoll

I also see later in the log that

2020-11-18 19:17:56,869 DEBUG blacklist expr '^postgresql-.*(0-9)(0-9).*' matches 'postgresql-10-debversion'
2020-11-18 19:17:56,869 DEBUG The package 'postgresql-10-debversion' is marked for removal but it's in the removal black
2020-11-18 19:17:56,884 ERROR Dist-upgrade failed: 'The package 'postgresql-10-debversion' is marked for removal but it
is in the removal blacklist.'
2020-11-18 19:17:56,884 DEBUG abort called

so it’s possible the “unofficial software” warning is a red herring.

Has anyone successfully done a release upgrade on a server running Landscape?

Proxmox vs OpenStack


We are working on OpenStack in the past few months to get it working on our lab and well it is up but it is very complex and time-con… | Read the rest of

google cloud platform – How to Lift and Shift from OpenStack to GCP?

I have previously had an OpenStack based cloud environmnent in which I had virtual servers. I have migrated to GCP and while I’ve refactored everything to be cloud native (and especially k8s), I’d like to move the disk images to GCP for archival purposes and so that I can access them by starting an instance in GCE.

I’ve made a snapshot of a server and downloaded it with glance cli tool, but I have hard time getting it work in GCP (If that’s even possible?). I’ve tried importing it as an image both on GUI and CLI. If I denote the OS (Centos 7), the import process does seem to find it in the raw disk image, but the import process ends with

(import-image): 2020-09-23T08:22:48.732Z step "translate-disk" run error: step "wait-for-translator" run error: WaitForInstancesSignal FailureMatch found for "inst-translator-import-image-translate-disk-1zq15": "TranslateFailed: error: Verify that you have specified the correct operating system in the `--os` flag. If you are bringing your own license (BYOL), also verify that your subscription is eligible to be run on GCP."

If I don’t denote the OS, the import succeeds but the instance is not bootable from the image.

So my questions are: Is what I’m trying to do actually possible and if so, how? What am I doing wrong? Is there a better way to do this?

router – Where is the vRouter in Openstack?

so this sounds like a philosophical existential question here… but I’m wondering…If I have a stack, with a bunch of VM’s all on compute nodes in my environment. ANd I create a vRouter for one particular network to use as a gateway… Where is that vRouter located? Is it on one of the Neutron controller nodes? Or is it on the compute nodes that have a network interface to that vRouter? What happens if the node where the vRouter is taken out of service, is the connection lost? Is there anyway to move the vRouter from one node to another?
