Hi,
I'm unclear as to the recommended usage of vnets in configuring LDOMs-
specifically:
Assuming I have two ldoms (guest0, guest1) which should sit on the same
network, and one vswitch (primary-vsw0) connected to that network.
Should I create two vnets on primary-vsw0 and connect one to each ldom, ie:
ldm add-vsw net-dev=e1000g0 primary-vsw0
ldm add-vnet vnet0 primary-vsw0 guest0
ldm add-vnet vnet1 primary-vsw0 guest1
The vnet name is unique to a guest so you can have vnet0 in both guest0
and guest1. Think of it as an instance number of the vnet in that
guest. I could call them anything not just vnetx
So for each guest I could have a vnet0 and this would be perfectly correct.
Or should I create one vnet and add it to both ldoms, ie:
ldm add-vsw net-dev=e1000g0 primary-vsw0
ldm add-vnet vnet0 primary-vsw0 guest0
ldm add-vnet vnet0 primary-vsw0 guest1
The second option is much less intuitive to me since I think of the vnets as
virtual network cards, but I've seen this in several places and both options
seem to work.
Which is better and why?
Think of them as virtual network cards in the guest ldom. Just as in
each physical server you may have an e1000g0, you would not make this
unique amongst all of the servers in your estate.
Either is equivalent - the name doesn't mean anything outside of the
local guest reference, but must be unique within the guest.

Thanks,
