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