Hi Sokratis, thanks for the feedback. We have an RFE[1] opened to allow changing shares dynamically for a VM while it's running. As you probably know VMWare's implementation handles much more than shares, so it's a wider concept. In oVirt we've been working hard to introduce QoS elements during 3.3 and 3.5 versions[2]. Once we have it all in place we'll start heading for the next level (up) which will be a Policy to aggregate QoS aspects for a VM. Once we have a policy you'll be able to assign it to multiple VMs and have much better control over resource including a planning element. So you should be monitoring the Policy task progress once we start working on it. So... as you can understand this is a lot of work (which I'm sure was the same for VMWare when they did it). Until then you'll be able to handle it using [1] I expect to happen in the next version, and as always- patches are welcomed!
