[Engine-devel] [ATTANTION] NetworkManager - STP

[Alon Bar-Lev]

Hello,

On recent fedora-18 NetworkManager started to set default STP for the bridges to on, this is a change in the default of distribution, which up until now was off, I opened a bug[1].

If you experiencing disconnect of hosts from network due to STP detection, a workaround is available.

Simply add:
---
STP="off"
---

To the wired interfaces (eth0, em1...) before host deployment, this will be copied to the management bridge and will prevent NetworkManager to use its default.

Regards,
Alon Bar-Lev.
