Linux bridge RTNETLINK exists

Hi,

I am running Mitaka on Centos 7 and am getting the following error in the linuxbridge log on the network node

RuntimeError: Exit code: 2; Stdin: ; Stdout: ; Stderr: RTNETLINK answers: File exists

I am able to have VMs connected to the public network however VMs created on private networks have no network connection

Thanks

Alex

Linux bridge RTNETLINK exists

EDIT: I have updated the behavior I am seeing

Hi,

I am running Mitaka on Centos 7 and am getting the following error in the linuxbridge log on the network node

RuntimeError: Exit code: 2; Stdin: ; Stdout: ; Stderr: RTNETLINK answers: File exists

I am able to have VMs connected to the public network and private networks however VMs interfaces created on private networks have no the network connectionnode never leave the BUILD state

Thanks

Alex

Linux bridge RTNETLINK exists

EDIT: I have updated the behavior I am seeing

EDIT2: I have added the running command from the debug

Hi,

I am running Mitaka on Centos 7 and am getting the following error in the linuxbridge log on the network node

RuntimeError:

existss

I am able to have VMs connected to the public and private networks however interfaces created on the network node never leave the BUILD state

Thanks

Alex
