Apache Cloudstack on Hetzner / Ubuntu 2404

[dacrudg]

Hi,

I've been following the guide at: https://rohityadav.cloud/blog/cloudstack-kvm/

I was wondering if anyone could take a quick look at my Apache Cloudstack netplan config on Ubuntu 2404 / Hetzner. Every time I "netplan apply" it disconnects me from my SSH connection.

This is the only netplan config that comes with the server by default:
In /etc/netplan/01-netcfg.yaml

network:
version: 2
renderer: networkd
ethernets:
enp6s0:
addresses:
- 157.185.50.140/32
- 2a01:4f9:3100:42c3::2/64
routes:
- on-link: true
to: 0.0.0.0/0
via: 157.185.50.129
- to: default
via: fe80::1
nameservers:
addresses:
- 185.12.64.2
- 2a01:4ff:ff00::add:1
- 185.12.64.1
- 2a01:4ff:ff00::add:2

I've tried many different variations of the config example with no luck. I don't have any additional IPs from Hetzner. I was hoping I could just configure the local box to keep the external IP it gives me, and use a 192.168.0.0/24 private network for Apache Cloudstack internal networking, all of it running on the same host.

Any help would be much appreciated. Thank you!

Hi decrudg

I post my comment to your question here as well, because I'm not sure if the mailing list email gets attached to the github issue.

I think the problem lies with your defined netmask for the 157.185.50.140/32 ip address. The /32 implies that this is a host netmask and with this ip/netmask your VM cannot contact your default gateway.

You have to find out what the effective subnet mask for your network is that hetnzer assigned an ip address from.

If you connect through ipv6 to your hetzner vm, then I don't know the problem, based on your netplan config.

Cheers
