[Engine-devel] quantum-ovirt integration meeting summary

[Livnat Peer]

Hi All,

This is a summary of the first quantum-oVirt integration meeting.

In the meeting Garry Kotton started presenting his proposal for the
integration, for more details on his proposal look in -
http://www.ovirt.org/wiki/Quantum_and_oVirt

We did not cover much of the wiki as some question arose:

* What is the end goal of the integration? is it to replace the current
network configuration implementation in oVirt by quantum or have them
side by side.

- we need to remember non-VM networks (like storage and migration networks)

* Will oVirt use multiple quantum instances, one per technology, or will
oVirt use a single quantum instance that should support multiple
plug-ins (not supported in Quantum ATM)

* We'll oVirt support a mix of different technologies in a DC, Cluster,
host?
- Can we assume homogeneous clusters for the sake of simplicity (in a
single cluster we'll support either open Vswitch or UCSM or ..)
- Logical Network is defined in the scope of a data center, that means
we need to maintain layer 2 connectivity and within a cluster we need to
guarantee VM live migration (does libvirt abstract it for us?)


other notes -

* The UUIDs that are returned by Quantum will be managed by oVirt and
for a single network implemented in two different technologies in
quantum oVirt will be responsible to sync the different IDs.

* The integration should be as seamless as possible to the user of oVirt

* support of existing VLAN in quantum should be introduces in quantum in
a 3-4 weeks time-frame



Comments are welcomed, I'll schedule a follow up next week.

Thanks, Livnat
