I see this was very misleading, sorry. With the phrase 'witch is what
I do now' I literally meant 'right now' witch is not (yet) oVirt/vdsm
but plain libvirt / virsh / virt-manager.
Since libvirt supports OVS directly; I just use <virtualport
type='openvswitch'/> in my network xml; then define VLANs and QoS with
ovs-vsctl cli. So I am used to OVS management and the flexibility it
offers.
I was also trying to mangle things in oVirt - but I could not get OVS to
work with oVirt managed bridges and gave up (since I cannot use such
'hacks' in production environments, company and my own policy).
Thanks!
PS: I hope I made myself clear in my last mails, OVS is not the 'killer'
feature witch decides whatever I deploy oVirt or not. Linux bridge and
libvirt network QoS are well tested. But I will surely miss some things
later on I cannot do directly. What I do with it and what I use it
currently for - please refer to my mail to Livnat.
