i have only 4 gb in ram Alexey

So just try it ;)

but i got error

i have only 4 gb in ram Alexey

This is too little ))

VMWare ESXi use 8Gb for internal tasks 😁

but in esxi i should i have real server ?

but i got error

Maybe you should try to disable some unneeded services in this deployment? Do you really need Swift, Ceilometer, Heat in this particular installation?

but in esxi i should i have real server ?

at least physical

Denis i have just my laptop

Alexey what the command to verify this component on my installation

Denis i have just my laptop

Installing on such a small RAM is a bad idea.

is just for project in class that i should to prepare

i should to create an vm inside openstack

you can not do it without additional ram

no any normal way

old vmware 5.5 need al least 4 - ESXi requires a minimum of 4GB of physical RAM.

you can try something very old, as 5.1 - ESXi requires a minimum of 2GB of physical RAM. Provide at least 8GB of RAM to take full advantage of ESXi features and run virtual machines in typical production environments.

can u give me video

which sort of video do you need ?

because i don't know how i use esxi on my laptop

and i don t have any server

because i don't know how i use esxi on my laptop

You need USB drive to install vmware esxi on it, and a lot of command line commands, so it's not an easy task and perhaps bad idea

What OS is now on your laptop?

windows 10

so just activate hyper-v

i did not found hyper -v

features on my windows

what edition Win 10 do you have ?

win+r - winver

you should have Windows 10 Enterprise, Pro, or Education

https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v

So, let's summarize.

You don't have ram to run Openstack

You don't have hyper-v

You definetly can't run esxi too, (ram problem . again. and you will need second PC or noteboot to see web GUI)

so https://pve.proxmox.com/wiki/System_Requirements

maybe xen or kvm

ok if i install kvm

maybe https://www.vmware.com/products/workstation-player.html

then i will install centos

ok if i install kvm

What do you want to do, by the way ? What is you task for it ?

i need to find a way to install devstack

because i have vmware workstation 15 pro

No way

Devstack just a pack of scripts to install openstack

for openstack you nedd at leats 16 Gb RAM.

but i heared that i need 6gb in ram

8 gb

The following minimum requirements should support a proof-of-concept environment with core services and several CirrOS instances: Controller Node: 1 processor, 4 GB memory, and 5 GB storage Compute Node: 1 processor, 2 GB memory, and 10 GB storage

https://docs.openstack.org/newton/install-guide-rdo/environment.html

https://docs.openstack.org/install-guide/overview.html

8 gb

8 just for see how it's install.

i have only 4 gb in ram Alexey

so you have only 4

yes

so maybe you can try to do it on online lab, as AWS maybe

like this https://www.youtube.com/watch?v=du94N1Yd7lM

yes but i should i have an rdp

thank you so much Der for your time

yes but i should i have an rdp

A rdp from where to where ?

i mean an account in aws

or google cloud

so what a problew with it ? as I remember, they give a time to test

but you should have an card

but you should have an card

As I rememeber, even in Iran - MasterCard works over Iran Post

i m not from iran

and i dont have a card yet

i m not from iran

It's only one country with such problem, as I remember.

and i dont have a card yet

so, it's problem.

yes

I cannot remember, are yellow bricks asked for card or not.

Der thank you so much

Der thank you so much

you welcome. Just for info - why you need an openstack? what will you do with it ?

i want just to create vm inside openstack

is my project in class
