We need to know if the guest will ever set bus master enabled or not, so we can have a compat hack in qemu to not check for it. > > > Alex This patch fixes hotplug with qemu 0.11-0.12 which can't make use of a new identifier without a time machine. IMHO we can't add new identifiers in time for 2.6.34 anyway, so if you want to do that, please send a patch and have it queued up for the next release. But I don't think we need an identifier for compat hack. Hypervisor can detect buggy guests when they set status to OK without enabling bus master first.
