There is a bug report for this problem that says a fix will be integrated into b132, which is just a few weeks away, but in the mean time, I’ve whipped up an SMF service to handle this for me. Create a file vnic.xml:

<?xml version="1.0"?>
<!DOCTYPE service_bundle SYSTEM "/usr/share/lib/xml/dtd/service_bundle.dtd.1">

<service_bundle type='manifest' name='vnic'>

<service
    name='network/vnic'
    type='service'
    version='1'>

    <dependency
        name='network_service'
        grouping='require_all'
        restart_on='none'
        type='service'>
        <service_fmri value='svc:/network/service' />
    </dependency>

    <dependent
        name='network_vnic'
        grouping='optional_all'
        restart_on='none'>
        <service_fmri value='svc:/system/zones' />
    </dependent>

    <exec_method
        type='method'
        name='start'
        exec='/usr/sbin/dladm up-vnic ${SMF_FMRI/*:/}'
        timeout_seconds='60' />

    <exec_method
        type='method'
        name='stop'
        exec=':true'
        timeout_seconds='60' />

    <property_group name='startd' type='framework'>
        <propval name='duration' type='astring' value='transient' />
    </property_group>

    <stability value='Unstable' />

    <template>
        <common_name>
            <loctext xml:lang='C'>
            Virtual Network Interface
            </loctext>
        </common_name>
        <documentation>
            <manpage title='dladm' section='1M'
                manpath='/usr/share/man' />
        </documentation>
    </template>
</service>

</service_bundle>

This service should run sometime after the network is started but before the zones are started. Load it in with svccfg -v import vnic.xml and create an instance of the service for each of the VNICs that you want to start. For example, if you want to start vnic0 on boot:

# svccfg -s vnic add vnic0
# svcadm refresh vnic0
# svcadm enable vnic0

UPDATE: Build 132 is out an this functionality has been integrated as the svc:/network/datalink-management:default service. The services that were added above can be removed by running svccfg delete vnic.
