I'm very new to bhyve and am having an issue. I'm trying to get VM's and
VLAN's working.
I'm able to get VLAN's working in a VM, but the VM and the VMHOST, can't
communicate with each other on the same vlan.
Using 10.1-RELEASE-p9 for both VMHOST01 and DEV. Upstream from the
VMHOST on lagg0 is a Cisco 3750G.
VMHOST01 before starting VM:
bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric

VMHOST after starting VM (added tap0 & bridge0):
tap0: flags=8902<BROADCAST,PROMISC,SIMPLEX,MULTICAST> metric 0
mtu 1500
options=80000<LINKSTATE>

member: lagg0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
ifmaxaddr 0 port 4 priority 128 path cost 10000
Note that the "status: no carrier" is because I hadn't brought up the VM
yet. It properly changes to the following after the VM is started:
tap0:
flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=80000<LINKSTATE>
ether 00:bd:70:71:1d:00

media: Ethernet 10Gbase-T <full-duplex>
status: active
vlan: 100 parent interface: vtnet0
With this configuration, both VMHOST01 and DEV can communicate anywhere,
EXCEPT to each other using their IP on VLAN100.
The ultimate goal is to have more than one VLAN presented to the VM,
whether it exists on the VMHOST or not.
Where did I go wrong?
Thanks in advance,
scotto
