[ovirt-users] Networking

I'm trying to create vlans to mirror my vlans on my external switch. is there a simple way to simply define a port trunk and have ovirt engine pass the traffic on? In VMWare; this can be accomplished by nic teaming/trunking (802.3 ad) and then pass the traffic to the switch. >From what I have re

Hi Mike, I'd like to say that though setting ovirtmgmt as non vm as a default should be nice, it won't be enough as it won't allow to use mixed traffic in other interfaces either, so the way I see it, the fix should be to add this ability to ovirt. I can't make my mind to think what a big corporat

Quoting "Dan Kenigsberg" : This was devised as a security constraint - otherwise, a VM attached to the non-VLAN network could sniff traffic from another (VLAN) network. However, it seems that this is exactly what you need - a special VM that is designed to do just that. Well, I would prefer it

Just as a quick shot: it is possible to configure it the way you want (ip-less bridges), but I can't exactly tell you what you're doing wrong atm. ip-less bridges work here with vlans and stuff, so keep trying or post more info about your setup :-) Am 09.01.2014 09:22, schrieb Alan Murrell: > On
