virt-in-virt problem: DHCP failing for a container in a oVirt VM
--_000_F3282EEAFF180F43BAF1AD0A7C34739D3DA20Enjmailneclabscom_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi all, Have an interesting problem - I am running a VM in oVirt that is running Pr= oxmox VE 4.1 OS, which I have spun up a container on. The container is set= for DHCP, and I have verified that it is sending Discover packets as norma= l, and that these packets are making it out of the Proxmox VM to the oVirt = bridge (which is attached to a VLAN sub-interface of a bond interface.) How= ever, these packets do NOT make it past the oVirt bridge. The interesting t= hing is that the Proxmox VM (as well as any other VM I spin up on oVirt) wo= rks fine with DHCP. (I also have other oVirt VMs instantiated which are usi= ng LXD to spin up containers, and I have the same problem with those as wel= l.) I checked a bunch of stuff, and the only clue I could find is that it s= eems that the oVirt bridge is not learning the MAC for the container on the= VM, even though it does learn the VM's MAC, but I can capture DHCP traffic= coming from the container off the 'vnet0' interface which is joined to tha= t bridge...
