hi ,

i have setup controller, compute node using  devstack  .
i launched two instances ..
 qvo998f715f-93  ,  qvoc3d0875a-0e  are created in br-int.

i would like to know   the pattern of qvo interfaces .
suppose i launched another instance , what would be the next   qvoxxxxxxx-xx interface name  created  in  br-int  .
is the pattern random or can be predicted .I am interested in the pattern of qvoxxxx-xx  interfaces . i have some requirement .

 ip address of the instance attached to qvo998f715f-93  ,  qvoc3d0875a-0e are  10.0.0.34 , 10.0.0.35 .
