[pve-devel] corosync, multicast problem because of vmbr multicast_snooping enabled

[Alexandre DERUMIER]

I have compiled it from git,works fine here.

What is your problem exactly ?


Note that I think you need to disable igmp snooping on all nodes at the same time, 

because it's possible that nodes with igmp snooping enabled won't see the nodes with igmp snooping disabled.

I removed the kernel from the pvetest repository, because it breaks multicast totally. 

So please compile yourself, code is in git.
