...can be done from the virsh interface. Thanks Juerg! 1) down the vnetX interface from the host node ip link show dev vnetX ip link set down vnetX ip link show dev vnetX And if using bridged networking, you have one more option. 2) remove the vnetX interface from the bridge brctl delif <bridge_int> vnetX Certainly downing the interface using either Juerg's solution via virsh or mine via iproute2 tools is most ideal since it's easier/simpler to reinstate. You can use ifconfig if you prefer it over ip tools, but enjoy those tools and syntax while it remains! [0] ;-) [0] https://...

...iance" VM is connected to both this and the external interface. I take it you've tried testing basic connectivity from the VMs to whatever default gateway is in place? I see Spanning Tree is enabled, so you might check that an interface isn't in the blocking state. brctl showstp <BRIDGE_INT> | egrep '^(em|eth|vnet)|state' I don't use the NAT network mode for KVM, so hopefully someone else can chime in on that piece. -- ---~~.~~--- Mike // SilverTip257 // -------------- next part -------------- An HTML attachment was scrubbed...

Hi Mike, Thanks for the info. I'd rather run monitoring such as tcpdump from the VM if possible and not the host as a simulation of a network appliance and with the intent eventually of giving others access to the VM and not the host.
