Description
If you create an overlay and configure it to bind to an IP address which is not available, then it is not possible to create any VNICs on top of it. The error message returned in this case is, however, rather unhelpful.
bloody% pfexec dladm create-overlay -v 111 -e vxlan -s direct -p vxlan/listen_ip=10.10.10.10 -p vxlan/listen_port=4789 -p direct/dest_ip=127.0.0.2 -p direct/dest_port=5555 ov0 bloody% bloody% pfexec dladm create-vnic -l ov0 test0 dladm: vnic creation over ov0 failed: operation failed
Creating the IP address allows the VNIC to be created (since the vxlan encapsulation plugin can now create the necessary listening port):
bloody% pfexec ipadm create-addr -T static -a local=10.10.10.10/29 vioif0/test bloody% pfexec dladm create-vnic -l ov0 test0 bloody% bloody% dladm show-vnic LINK OVER SPEED MACADDRESS MACADDRTYPE VID test0 ov0 0 2:8:20:ee:30:66 random 0 bloody% bloody% netstat -anu | grep 4789 10.10.10.10.4789 Idle
The error message here should be improved.
