Re: KVM networking issue

Thanks, Mike. When running tcpdump on the VM I'm not seeing traffic
unless it's explicitly intended for that particular VM, so no traffic
between the other VMs is getting forwarded from the virtual interface
to the "network appliance" VM.

There is connectivity between the VMs on the private network and the
"network appliance" VM which is acting as a gateway.

Here's the output of the brctl command:

I'm not sure why virbr1-nic is showing up as disabled, and also why
the vnet# interfaces don't show up (they do show up on another host,
although VMs on that host are having the same non-promiscuous issue as
these VMs). I've tried this with and without NAT, as well as with STP
on/off with no effect.

Thanks,

Kevin
