Not able to Add Host . KVM in Ubuntu. Dev code running in Mac.

[gjosh91]

Hi Community,

Need help stuck at adding Hosts through frontend .
I am in a bind and confused at this point . Please guide . This is my setup :
I have setup my cloud Development environment in Mac M2. I have started the backend services (using IntelliJ) , deployed the Db and started the front end (Using VSCode) .
I would like to bring to your knowledge that I have not separately setup my cloudstack management server as it was my understanding that running the backend service will itself act as a management server.
I have setup my cloudstack agent in the Ubuntu 22 machine . I have assigned the directories for NFS as mentioned in the official docs . I have also setup the KVM and checked if it is running. I have changed the configuration file for network managed by Netplan in my case . This is the network configuration file for your reference :
/etc/netplan/01-network-manager-all.yaml

network:
version: 2
renderer: NetworkManager
ethernets:
enp1s0:
dhcp4: no
vlans:
enp1s0.200:
id: 200
link: enp1s0
wifis:
wlp2s0:
dhcp4: false
dhcp6: false
access-points:
"WIFISSID": # Replace with your WiFi SSID
password: "WIFIPASSWORD" # Replace with your WiFi password

bridges:
cloudbr0:
interfaces:
- wlp2s0
addresses:
- 192.168.1.95/24
routes:
- to: default
via: 192.168.1.1
nameservers:
addresses:
- 8.8.8.8
- 8.8.4.4
search:
- lab.example.org
parameters:
forward-delay: 0
stp: false
max-age: 1
cloudbr1:
interfaces:
- enp1s0.200
dhcp4: no
parameters:
forward-delay: 0
stp: false
max-age: 1

Now both the machines are able to ping each other. They are connected over a private Wifi network . I am able to ssh from Mac into Ubuntu .

My problem is occurring when I am adding Host . While adding Host I am inputting the . But it is giving Error 503 that no service resource found at http://ipaddress .

Please guide if I am missing something or doing something wrong.
P.S. I am new to everything cloud and if you are thinking that I should already be knowing that and not mentioning it in your answer please do mention it .

@gjosh91 can you also reach for instance port 8250 on the host from the management server? This is needed for communication.
Can you examine the logs on both machines ? (/var/log/cloudstack/agent/agent.log and /var/log/cloudstack/management/management-server.log respectively)

[gjosh91]

Can you please elaborate. I want to run the Management on Mac . I have not initiated any management instance seperately and am running the backend code which as per my understanding should act as management server.

My KVM and agent is running on host Ubuntu .

[DaanHoogland]

On the mac you can reach 8250 , so that side seems to be functional for this part.
On the host an agent should be running (check systemctl status cloudstack-agent).

[gjosh91]

My agent is running.
cloudstack-agent.service - CloudStack Agent

[DaanHoogland]

good, nothing wrong there.
Long shot, but can your host reach the storage you have provisioned?

[gjosh91]

@DaanHoogland Can you please suggest how to do this ?

@gjosh91 your setup will not work as Mac OS isn't a usually supported development platform for use with remote KVM - you'll need to figure out yourself how to do this and may be share with us - how you made it work!

I suspect there's some mount and other commands that aren't working on the mgmt server that you're trying to run on OSX, while your hypervisor host is on Ubuntu/KVM. Even if you figure out/install those dependencies, the issues is further that GNU tools aren't compatible on OSX when installed using brew, the same way to setup/install on Linux (Ubuntu, Fedora). Most of us who use CloudStack development on OSX, actually use Simulator (see https://github.com/shapeblue/hackerbook and https://github.com/shapeblue/hackerbook/blob/main/2-dev.md#simulator-based-development) From my own experience, it's not worth spending time to figure out something that just works out of the box on Linux/Ubuntu for example.

That said, @gjosh91 here's a workaround - you can install/setup an Ubuntu VM on your OSX machine using UTM or Parallels and setup your development env in it instead.

[gjosh91]

@rohityadavcloud thank you sir for your valuable suggestion. I will try the ubuntu way going forward or the VM way.
Although this is not in the purview of my question but just to bring it to your knowledge the dev cloud image link referenced in the Latest document for release 4.19 is not functioning.

I will still try if my approach is possible in Mac and select an answer for this question accordingly.
Thank you for your valuable feedback.

It's been long that we've used/maintained DevCloud, nowadays most of the developers DIY something (either docker or VM/appliance based) of their own, or use Simulator or mbx: https://github.com/shapeblue/mbx
