Hello, I am trying out VMM on an OpenBSD 6.4 server which has the following network interfaces defined:
[bnx0]+[bnx1]-->[trunk0]-->[vlan2] [bnx0]+[bnx1]-->[trunk0]-->[vlan6]-->[bridge6] The vlan2 is for the internal (management) network and vlan6 for the public (internet) network. I manage my server from vlan2 and would like to have my virtual machines on vlan6 which uses public IP addresses. For that purpose I have setup my /etc/hostname.* files as such: hostname.bnx0 + hostname.bnx1: up hostname.trunk0: trunkproto failover trunkport bnx0 trunkport bnx1 up hostname.vlan2: inet 192.168.1.5 255.255.255.0 192.168.1.255 vnetid 2 parent trunk0 description "private" hostname.vlan6: vnetid 6 parent trunk0 description "public" up hostname.bridge6: add vlan6 I am actually using Option 4 from the Networking chapter in the virtualization FAQ (https://www.openbsd.org/faq/faq16.html) just that my setup has a redundant link (trunk0) and a VLAN (vlan6). So in theory that should work but unfortunately when I start a VM to install OpenBSD 6.4 from the bsd.rd boot file I do not have any network connectivity. I tried with DHCP first and in that case on the DHCP server I see the DHCPDISCOVER and DHCPOFFER requests/answer but there is never a DHCPACK. Then I tried assigning a static IP directly but still no network connectivity. I can't ping the default gateway of that public network. Checking with tcpdump on the firewall I can see the ARP who-has request and the ARP reply back the the VM but again it seems like the VM does not get it. Here is my vm.conf conf file: switch "uplink_vlan6" { interface bridge6 } vm "example" { disable memory 2G boot "/home/admin/bsd.rd" disk "/var/vmm/example.qcow2" interface { switch "uplink_vlan6" lladdr fe:e1:bb:01:01:01 } } I have also totally disabled pf on that OpenBSD VMM server but that did not change anything (I am using the default pf.conf from the installation) Any ideas what I might be doing wrong or forgetting? Regards, Mabi
