[Ray Sun <qsun01185@xxxxxxxxxxxxx>]

Hirai,
Thanks for your quick response. Currently I am using nova-network in VLAN
model. Actually the real requirement is the user want to bind many
subinterfaces on one NIC, and they want to connect the other server using
every subinterface, so we can't want to create so many VLANs for one
project.

- Ray
Yours faithfully, Kind regards.
