[ovirt-devel] 答复: [ovirt-users] How to add ovs-based VM in version 4.0.2? Thank you

Tue Aug 2 12:15:21 UTC 2016

Hi Petr,
	Thank you
	When the patch will merge to master? And when will the vdsm will release a version with this patch?
 	Btw, do you have a plan to support ovs with dpdk or vhost-user port?  If so, what's the pipeline?

Thank you

Clean == host that has just NICs, like right after system installation (no networks created by VDSM, bridges, bonds, vlans). Anyway, VDSM OVS is not able to acquire external NICs yet (the patch is under review and will be merged to master soon [1]).

I would recommend you to wait for VDSM with mentioned patch merged. If you cannot wait, you can try to setup ovirtmgmt network manually via console (turn down NIC, setup OVS network on top of it). Not sure if this would help you.
