Agreed, I don't really consider that document very useful in terms of identifying what is the "minimal required functionality" for a usable virt driver. It is far too terse / leaves out loads of detail. > For example, there are 3 rows with graphical consoles: VNC, spice and RDP. > All > 3 consoles do the same thing, so I think VNC console support is enough, am I > right? Currently the only ways to interact with a VM are over the network (eg SSH) or via the graphical console (VNC or SPICE or RDP). I think it is reasonable to say a method of interaction is required that doesn't rely on the network/ssh. So currently I'd say at least one of the graphical console methods is a requirement. For Juno though, there is a blueprint adding support for direct interactive serial console support. Once that lands, then I don't think graphical console support should be a requirement - serial console is a valid alternative to target. > Also I think networking support should include vif types, which driver > supports (VIF_TYPE_BRIDGE, VIF_TYPE_OVS, VIF_TYPE_IVS and others), and if a > drivers claims to support VIF_TYPE_OVS it means than it supports all > features, > supported by openvswitch and ML2 neutron plugins (floating IPs, flat > networking, security groups, vlan networking). > So is it enough to implement OVS vif type? IIUC, VIF_TYPE_BRIDGE is the only one that works with Nova network, so I'd consider that one a prerequisite. I'd probably suggest VIF_TYPE_OVS is pretty close to a prerequisite too, since as you say, it enables a lot of the Neutron functionality.
