Hello. I am dealing with a weird networking issue that I never experienced before and I really can't find anything relevant in logs or else. The setup is like this:
* Kvm hosts with 2 slave interfaces (for redundancy) under a master bridge called br0 * The 2 interfaces are connected to 2 stacked Cisco switches * Traffic for management, guest, public, etc. goes through this bridge only * ACS zone added with advanced network, br0 label set on each traffic type Everything seems fine, the system vms are up & running, hosts are added without issues, etc. The cloud0 bridge is created on each host as it should. Now, if I add a vm on a certain host and the virtual router (simple, isolated network) is on the same host, everything works fine, the vm gets its own ip, dns, internet conectivity, etc. But if I add a vm to a different host than where the VR is hosted, I don't get any network for the vm. The virtual interfaces are created on the host but the cloud0 bridge status is either down or unknown. Could this be related to the hardware setup or it's something ACS related? Thank you!
