Hi, while launching VM using glance, we specify vif type as e1000 and virto. But If I want to change later the vif type as virto from e1000 how do I do that? If I change nova.conf to use virtio does it effect all the VM's on that compute node irrespective of which private subnet they belong to? Can any one please clarify on this. Thanks, Shiva -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-operators/attachments/20160223/290ddc88/attachment.html>
