Re: How to make the subinterface connection in a VLAN environment?
Hi,
Which network compornent do you use ? nova-network ? quantum ?
If my perception is correct, you need to use quantum to have
multiple nic on VM. When you create multiple subnet, VM will boot
with multiple NICs and these VMs can take communicate with each
others with each NICs.
