Subject: bonding and SR-IOV -- do we need arp_validation for loadbalancing too?
Date: Tue, 24 Jul 2012 09:57:03 -0600 [thread overview]
Message-ID: <500EC5CF.3080400@genband.com> (raw)
Hi all,
We've been starting to look at bonding VFs from separate physical
devices in a guest, but we've run into a problem.
The host is bonding the corresponding PFs, and it uses arp monitoring.
What we have found is that any broadcast traffic from the guest (if
they enable arp monitoring, for example) will be seen by the internal L2
switch of the NIC and sent up into the host, where the bonding driver
will count it as incoming packets and use it to mark the link as good.
The only solutions I've been able to come up with are:
1) add arp validation for load balancing modes as well as active-backup.
2) put all the VMs in VLANs
Anyone have any better ideas?
Chris
