Hi,
I'm using libvirt and qemu on Debian Wheezy. I'm having a strange behavior. Guests can't connect to each other when they're on the same host.
On the host I'm using bonding (in active / backup mode) and vlan. It looks like this : eth0 \ / macvtap0 bond0 --- vlan222 eth1 / \ macvtap1 I thought it was a known problem that macvtap guests can't talk to each other ...?
guests can't talk directly to the *host*. They can talk to each other though, as long as "bridge" mode is uses. In "private", "vepa" and "passthrough" modes, *all* traffic goes only out to the switch, so any communication between guests must be via the switch (and if the switch doesn't support that, they can't talk).
