SUMMARY

SSVM and CPVM fail to connect to the management server 🔴 . Looks like a routing issue 🌎

My mgmt server sits on 192.168.1.1, but SSVM tries to connect thru the public IP on another interface 🙄

How do I change this in SSVM ?

> cat /var/log/cloud.log

Here's my routing table 👀

How and where do I update the management server address so that my SSVM can connect to the mgmt server 🙄 ?

I need SSVM to connect to my mgmt via eth1 on 192.168.1.1.

STEPS TO REPRODUCE

EXPECTED RESULTS

SSVM and CPVM connects to the mgmt server

ACTUAL RESULTS

SSVM and CPVM can't connect to the mgmt server

You can check global configuration "host"

[rajujith]

@tampler can you check the global configuration "management.network.cidr" as well.

@tampler can you check the global configuration "management.network.cidr" as well.

It's empty by default in ACS 20.0.0. When I set it to 192.168.1.1/24, cloudstack-ssh stops working at all 🙄

@tampler , have you found a resolution to your query yet?

Hi Dan

I couldn't fix this and was annoyed due to constant installation issues 🙄 . I've been using ACS since 2018 till 2024. The same installation issue with SSMV and storage occurred all the time 😞

So I dropped ACS usage in favour of other technologies and stacks so can't test/debug/validate this issue anymore.

Perhaps, I'll be back to ACS in future, but now I can't contribute and provide any feedback. Sorry 🙏
