Network traffic being mirrored
--=_4ab7acf68b2ea1ad39d80d5183539e8e Content-Transfer-Encoding: 7bit Content-Type: text/plain Hi guys, I am seeing network traffic being sent to all my VMs on one of my oVirt hosts, but not the other two in that same datacentre. The VMs are running CentOS, and I've been monitoring the sessions with iptraf, and can see traffic from all other VMs on that network being received by all other VMs running on this host which have an interface on that same network. Is this something anyone has seen, or could anyone suggest anything I should be looking at to further diagnose?

I'll keep an eye on it and feedback if I see a repeat, perhaps there is something I can do to provide some useful debugging information - open to suggestions?

Well, if it happens again I'd like the output of: vdsClient -s 0 getVdsCapabilites iptables -n -L ip -o -d link show
