[one-users] KVM Migration with 802.1q on SLES 11 SP2 results in IGMP Flood

[Stefan.Steinert at brodos.de]

Default Title 
Hello One Users, 

 
I'm currently deploying OpenNebula on an IBM BladeCenter whose Blades OS are based on SLES 11 SP2 with an attached NFS Storage for the VM Images. 
To integrate the VMs in our network I'm going to use the 802.1q Module. 

 
The whole system is working, except one little thing :) 

 
If I try to migrate (Live and normal) the remaining network interface on the host on which the VM ran before starts to flood the whole Network with IGMP queries. That results in blocking my switches (BNT Layer 2/3 cooper gigabit + HP procurve 2824), so no more data will be transfered. 
If I shutdown the vlan tagged interfaces on the old machine with "ifconfig eth2.100 down" for example, the network gets fully operational again. 

 
Is there already a way in Opennebula to bring down these interfaces, which I only have to add the currently empty clean script? 

 
Or does anyone know how to prevent that igmp flooding on system side? 


regards 

Stefan
