[Starlingx-discuss] StarlingX All-in-one (AIO) Simplex with only one NIC

Hi Vitalino,

OpenStack services are provided by applying the stx-openstack application to your system. This application is not applied/installed by default.
So, you will need to download the application and apply it to your system.

Before doing it though, you should refer to the documentation with instructions on how to plan and prepared your system to have the OpenStack application deployed:

  *   Planning - OpenStack: https://docs.starlingx.io/r/stx.8.0/planning/index-planning-332af0718d15.html
  *   Node labels: https://docs.starlingx.io/r/stx.8.0/node_management/openstack/using-labels-to-identify-openstack-nodes.html<https://docs.starlingx.io/r/stx.8.0/node_management/openstack/using-labels-to-identify-openstack-nodes.html#using-labels-to-identify-openstack-nodes>
  *   StarlingX OpenStack installation: https://docs.starlingx.io/r/stx.8.0/deploy_install_guides/release/openstack/index-install-r7-os-adc44604968c.html

Please pay attention to the amount of physical hardware you will be able to provide to your system.
In theory you can apply the app on a virtualized installation of StarlingX and launch VMs within it, but it all boils down to how much computational resources you will be able to provide.
You mentioned 4 cores (8 Threads), you need to discount the minimum number of CPU cores required to be assigned to the platform (i.e., 2 cores if I'm not wrong) and the remaining number of CPU cores will be available for both the application (i.e., kubernets pods) and the VMs you will launch with it. Then you can start by using shared cores and if you have enough room, play with configuring dedicated cores for your VMs.
I personally had a hard time on launching VMs from within a virtual deployment with only 4 cores available, but I did not have 8 threads on that system.

Hope this is helpful for you to get started and please do not hesitate in contacting the stx-openstack community using this mail list or the StarlingX Matrix room.
By the way, our team meets every other week on Tuesdays at 11:00am Pacific Time. Next team meeting is planned for Aug 29th. You can find information about our meetings here: https://wiki.openstack.org/wiki/Starlingx/Meetings#11:00am_Pacific_-_Distro_OpenStack_Team_Call_.28Bi-Weekly.29

Regards,
Thales Cervi

Cool.

And pod of OpenStack Nova does provision KVM VMs (and networks) via Libvirtd running bare metal on your Ubuntu?

Hey, Vitalino.

You should be able to get an All-in-one Simplex (AIO-SX) running on top of an Operating System via VirtualBox with that hardware. I have the following and I'm able to run an AIO-SX:

* Ubuntu 20.04
* Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz (4 cores, 8 threads)
* 32 GiB of memory
* 512 GiB SSD (but you might be good with only 240)

I think that I do not have resources for running StarlingX virtualized.

My environment has 1 machine with:
* Intel Xeon E5-2667V4
* 32 GiB of memory DDR4
* 240 GiB SSD Sata
* 1 NIC

Hi Vitalino,

have you tried to run StarlingX on a virtualized environment to execute your tests?

Hi

I saw that in the All-in-one Simplex configuration documentation, it is suggested to use three NICs.

Just for testing purposes with StarlingX, is it possible to configure it to only use one network interface?
