Guest VMs have no access to host-network or external servers
Software environment
- Operating system: Ubuntu Jammy Jellyfish LTS
- Architecture: x86
- kernel version: Linux 5.15.0-1028-aws x86_64
- libvirt version: 8.0.0
- Hypervisor and version: KVM 1:6.2+dfsg-2ubuntu6.6
Description of problem
Guest Vms have no access to networks other than their own.
Steps to reproduce
- Installed Cloudstack host (advanced networking) on a ec2 Baremetal instance.
- Connected the secondary storage to the management host -> cloudstack starts system VMs.
- None of the system VMs can ping it's host or any other server outside it's own network.
- The bridge configuration is correct according to the maintainers. AWS Support says the subnet config on ec2 is correct too.
Additional information
s-25-VM.log
I am quite new to libvirt, so it might be my fault that I don't find a main logfile in the /var/log/libvirt/ directory
Appart from that sudo virt-admin daemon-log-outputs
gives me
Logging outputs: 3:journald
Network conf of the guest VM that fails to connect anywhere: vm.conf
While this network config is working on the host ec2 instance: host.conf
Please let me know what more information I can provide! I am very thankful for any help!
