I published notes some time back about pair bonding for CentOS, applicable to Scientific Linux as well, t https://wikis.uit.tufts.edu/confluence/display/TUSKpub/Configure+Pair+Bondin...
Show us your /etc/sysconfig/network-scripts/ifcfg-br0, if you would. I particularly want to see your "BONDING_OPTS".

NetworkManager and system-config-network do not really handle pair bonding very well, so you've obviously set it up by hand. this is the point where, getting a paid license RHEL license for your KVM server gets you direct access to their support team.
My servers don't use NM. Cf. other discussions on the main centos list :)
In particular, post your bridge settings. I think they should be set to "failover", not to the other, more complex and load balanced settings, to avoid confusing your switches and possibly KVM clients.
This? Or is there more information available?
