I am trying to just install the whole thing (manager, single node cluster) on a single RedHat box for evaluation. I don't want to use the VM for now.
I am assuming you can simply install everything on a single server should you wish to (I may be wrong).
When I am in the wizard though, and I enter the FQDN of the host which is running the Cloudera Manager installations, it just hangs.

I have an existing JFrog/Artifactory Pro 7.27.10 RPM-based install (on a CentOS 8 VM) that I recently migrated to a new (Centos Stream 8 VM) running JFrog/Artifactory Pro 7.31.13 (also installed via RPM).
After copying my existing master.key file from the original JFrog install to the relevant directory, I started up the Artficatory Pro service on the new VM and proceeded to migrate my data using the "Simple migration with downtime" process described in this JFrog whitepaper. Everything worked fine, Artifactory is running as expected on the new VM and all my data appears good. I moved my frontend proxy DNS aliases over to the new VM and shut down the proxy on the old VM.
One problem I am now noticing is that in the Artifactory admin UI, the Monitoring > Service Status now doesn't appear to report my Artifactory/JFrog platform microservice status any more. It does show Artifactory with the correct backend IP address (running on port 8082) but then the "Status" shows "Online" with (0 of 0 nodes) and the ">" fold down arrow shows nothing when clicked. I went back to my old Artifactory instance and checked and it was still showing the single node with all of the individual JFrog platform service statuses properly.
My guess is that I missed something in the migration process and/or something else needs to be configured to allow the services to show up on the monitoring page, however I'm at a loss as to what this is or even where to look for it. I looked through the system.full-template.yaml but nothing seems obvious there. And while the Artifactory docs are usually fairly comprehensive, the page about monitoring doesn't seem to give much insight about how this is configured or what to do if it's missing. Also not sure if the initial startup of Artifactory on the new VM before I migrated by data affected how the monitoring was configured such that it now doesn't work with the imported data (unfortunately I didn't check the monitoring UI in the new VM before I did the data migration so I can't say for sure if it was initially working)
A couple of other details which may be relevant:
when migrating my VM, I kept the same (FQDN) hostname, but the IP address was different
I used the same frontend (nginx) proxy configurations on both the old/new VMs though I'm not sure if this is relevant here or not.
With the exception of going from CentOS 8 to Stream 8, the VM configurations themselves should be nearly identical as I create them from a kickstart (which was only updated for the new stream repo paths). Again not sure whether this is relevant at all here.
Any ideas on where I should be looking to figure out how to fix this?
We run Openstack with KVM as hypervisor and now need to run ESXi 6 or 7 inside a VM (nested virtualization). This is mainly for converting disks to proper vmdk disks, not really running any VMs under ESXi (that is why we are not using a barebone and run esxi as hv)
We run this very same setup under Proxmox without bigger issues, the main point was using the vmxnet driver for the NIX. That is exactly where we fail with Openstack. It seems there is no such driver, using e1000 does not working. Booting the installation iso leads to 'no nic found' in the very end.
We are using Openstack Xena with Debian-Buster as compute (running libvirt) on kernel 5.10/5.14.
Any hints how to get this up and running?
Using https://github.com/virt-lightning/esxi-cloud-images i managed to get it working for 6.5/6.7 but not 7.0.
One seems to not be able to install ESXi via ISO on the an OpenStack instance itself (directly), since no matter if you use e1000 (6.x) or e1000e (7.x) for the installation, the installer will not be able to find the NIC during the installation. Also for the 6.x installer under Openstack, it could not find any disks (with or without the SATA flag).
Instead, I used the repo above to build an pre-installed esxi images shipped via qcow - it is build on my local machine and thus my local libvirt. Not sure yet why this makes a huge difference, maybe the nova based abstraction or something else hinders Openstack (no verification yet).
Building the 6.5/6.7 based qcow2 image locally, importing it via glance (ensure you use e1000 for 6.x and e1000e for 7.x) and then creating a new instance.
This will get you up and running on 6.5/6.7 with proper DHCP and network configuration.
For 7.x the interface is detected, but somehow DHCP is not working. I tried with q35 and different other options, but could not get 7.x to work until know.
I created a fork at https://github.com/EugenMayer/esxi-cloud-images to

I want to install Openstack on CentOS 8(single node). I am having single machine (physical machine) where I want to install all nodes of Openstack. This setup I required for simulation only not production use.
I have tried to install Openstack using packstac 3 times but couldn't success.
I got different issues during installation:
1.In first attempt After installation, I tried to create instance, but not getting console of instances even after it got created successfully.
2. In second attempt, during deployment of instance, network not getting allocated.
3. In third attempt, it got stuck at packstack, puppet testing only.
I have followed below 2 links:
https://computingforgeeks.com/install-openstack-victoria-on-centos/
https://www.google.com/amp/s/www.linuxtechi.com/install-openstack-centos-8-with-packstack/amp/
I followed each and every steps mention in the likns.
I want to create two Ubuntu VMs on Openstack.
Can someone provide me some links/video, where I can get everything which is required to install Openstack on single node and create two Ubuntu VMs and assign network to them and test the connectivity between these two VMS.
Thanks in advance.
I would use official Packstack documentation. Note that you should start with a totally fresh Centos installation; i.e. don't try to install Packstack on a server where a previous installation failed (or succeeded).
You can also try Devstack. Its default configuration requires a smaller machine than Packstack (in my experience, 8GB RAM should be sufficient). Same remark: Start with a fresh installation of Centos or Ubuntu.
Microstack is another alternative. Its advantage is a very simple and quick installation; its disadvantage is a very strange (in my opinion) configuration and not a lot of documentation. However, it is suitable for your purpose. It claims to work on any Linux, Windows and MacOS; it does require snap.
I suggest directly installation onto Ubuntu Server.
some time ago I wrote a serie of posts in which I explained in detail how to install OpenStack Rocky. The 2 first blog posts ([1] and [2]) contain commands, examples, content of configuration files that cover common scenarios and tips for the successful installation of most OpenStack services (keystone, nova, glance, etc.) in a single node, and the third post [3] describes the installation of a computing node. This 3rd post is installed in a different node for the sake of making it easier to understand how nova works, but the installation can be safely carried out in the same node than the other components.
I find that the posts are short enough and are very easy to follow (I use that blog as my installation tips, and so I have used them for several deployments). The only caveat is that it is based on Ubuntu, but if you know about your installation, it should be easy to translate the installation to CentOS (some colleagues have used these tips for CentOS installations).
I tried to install Openstack several times last week (october 2021): a) with CentOS 8 Stream to metal hardware (real server) with devstack - no one version was installed (neither Master nor Xena & Wallaby, version Viktoria & below are not for Stream OS); b) Virtual machine with CentOS 8 Stream installed with packstack - installation was clearly successful (!), quite easy for install (according to official RDO project and its homepage), however there is the real problem with virtual and actual networking: no external network is accessible, router created was OK with external connection (router IP was detected successfully from outside) but no connection was possible from and to instance. So I conclude the Openstack package is not completely documented to resolve problems, however its installation can be quite easy (when successfully finish ;) )
Addition: Of coarse, there are resources with an information how network can be configured, official Openstack docs describes different network configurations as well (however it is difficult to find it for one click and being newbie), but anyway this system requires a lot of time to study before usage.
I am using openstack to create a Centos7 VM.
I can get the VM to run but the installer hits a snag at the first page.
It needs a Disk to install to (Installation Destination)
I thought this was the volume that I attached using the openstack app. I used the volume's edit attachments and it pops up saying it will attach it; the volume is never listed as attached to ANY instance I attach it to.
It also needs an Installation Source, which I was using the URL from the mirror site I used. Here is the URL:
ISO URL
I used the net Install ISO. I tried the same url for the installation source and I also tried the URL but change isos to os or this:
OS URL
Thanks for any help.
when you create VMs in Openstack you are not supposed to go through the installation process. In the cloud you use cloud images that are ready to boot.
You should use a Centos cloud image.
Try to load this Centos7 image into your openstack glance:
http://ubuntu.mirror.cloud.switch.ch/engines/images/2016-04-15/centos7.raw
You should be able to boot your VM and boot with the username centos and the public key you provide with cloud-init.
Is there any way to install OpenStack without using virtual box in a single machine?
You can install all openstack services(controller, compute, network) in a single node. But it's not recommended.
If you don't want to install virtualbox you can try VMware
You may also try LXC or XEN if you are using linux. Then create 3 virtual machines and install openstack 3 node configuration.
Yes, of course. Just make sure you have enough resources on the system (single machine) to bare OpenStack. You may use packstack do the All-in-One
deployment. Check out RDO.
There is a possibility of installing openstack(both 2 and 3 node architectures) in a single system. But, things are to be considered. Like the performance of the system used, the primary memory associated with it, the secondary memory that is available, e.t.c
If you're talking about development environment, sure! You don't need a VM at all, and can just install it on your laptop directly! Note that this is not a desirable configuration :)
Other ways are to use a different virtualization tool than VirtualBox, like KVM, or VMware stuff.
Virtual machine is nothing but a system with shared resources. Whatever we do on a VM can be replicated to an individual system.
Make sure you have VT enabled on the hardware , else you may have issues in creating instance on the Compute node.

Whatever you can install in single virtual machine , can also be installed on your machine directly.
After all your machine is much more powerful and stable than your virtual machine.
We use virtual machine just to leave our system intact in case something goes wrong. Just compare the time it would take you to delete and create another virtual machine with time and effort for formatting your entire laptop.
Also, we sometimes use virtual machine if we need to make a network of 2-3 computers for some functionality and we have got only one hardware.
I created with kvm virtual machünes on Ubuntu 14.04
If you create the virtual machines and the virtual networks you can use it.
For the easiest way if you use an orchestration/deployment tool e.g. Mirantis Fuel
Surprising no body talked about Dockers. You can run openstack in a docker container.
According to my experience, always try to install openstack on a fresh system( either on a freshly created VM or on a newly installed OS). I have installed openstack many times, and trust me no error will come just follow this link on a newly setup machine. For old system, I was stuck for 3 days, and only GOD knows where from the hell those errors were showing up.
PS: I have always tried ubuntu system.
