Fang, it looks almost like a duplicate of BZ#750695, but with a different summary. Am I missing anything? Regardless, it will be assigned to RHEL6.3 Thanks.

I don't think it is a bug ,at least not a virtio-win bug . Because RHEL guest also hit this ,re-assign to qemu-kvm component and add amit in cc list . *** Bug 750695 has been marked as a duplicate of this bug. *** (In reply to comment #3) > (In reply to comment #2) > > Fang, > > it looks almost like a duplicate of BZ#750695, but with a different summary. > > Am I missing anything? > > Regardless, it will be assigned to RHEL6.3 > > Thanks. > > I don't think it is a bug ,at least not a virtio-win bug .

I think this is a bug: management software may not come to know when a balloon value gets applied. I think we should fix this. The fix for bug 725621 will also fix this issue. So unless there's any objection, I'll do this and mark this bug as a dup of the other one. > I think this is a bug: management software may not come to know when a balloon

That's not really a bug - it is a feature request.
Setting balloon target has always been disconnected from the actual applied balloon limit, so if you want to know the actual balloon value you have to explicitly query it when you want to know. The guest OS can change its actual balloon limit up or down at will.
It would, however, be useful if QMP has an async event to notify a mgmt application whenever the actual balloon level changes. This would avoid the need for the mgmt app to periodically poll 'query-balloon'.
Alright, I'll close this bug as NOTABUG then. |
