Hi John.
I'm on 151014 2cac697.
There are a couple of other zones defined but not running at the time.
The problem happens with just one zone running and the kvm inside.
In the zone:
show-link:
LINK CLASS MTU STATE BRIDGE OVER
fw2z0 vnic 9000 up -- ?
fwo0 vnic 1500 up -- ?
fwl0 vnic 1500 down -- ?
fwl1 vnic 1500 up -- ?
fwl2 vnic 1500 down -- ?
fwl3 vnic 1500 down -- ?
fwo0 is attached to an rge0
fwl0-3 are attached to a four-port e1000g
fw2zo is attached to an etherstub.
show-addr:
ADDROBJ TYPE STATE ADDR
lo0/v4 static ok 127.0.0.1/8
fwl0/temp static inaccessible 10.0.0.1/24
lo0/v6 static ok ::1/128
kvm startup script:
#!/usr/bin/bash

VNICL1=fwl1

VNICL3=fwl3

the command.

public_nic=$(dladm show-vnic|grep fwl0|awk '{print $2}')
public_ip=$(ifconfig fwl0|grep inet|awk '{print $2}')

echo "Started VM:"
echo "Public: ${public_ip}:${port}"

I took the macaddr part off the vnic description, because at the time it
seemed to help reduce the issue - but no longer.
The usual error message I get from one of the vnics is "failed to bind
interface xxxx".
...and please don't assume I know what I'm doing - that's probably not
the case. ;)
