Subject: Re: [Engine-devel] Stable PCI Addresses design wiki
my notes:
why adding new parameter to create verb and not using the createInfo?
(or this is the intention?)
Yes, we will use the createInfo to pass that
if we expect xml to be large, perhaps it would be better to get it
from db only before sending it to vdsm,
to keep the vm object from getting too big, meaning never get it as
part of vm dynamic.
Sure , I have considered that (see Logic Design) in original document:
b. Get the domxml from DAL for each VM we are running (creating)
This will insure that our VM entities are not keeping the domxml inside them,
rather, they will got it on demand
