Re: [libvirt] [Qemu-devel] [RFC v2] libvirt vGPU QEMU integration

Any VM which uses the separate namespace is tainted, which means if theres a bug report we'll require the reported to remove whatever config caused the tainting and then reproduce the problem. If the vendor specific mdev parameters are things that apps will often need to be able to set, then allowing it via a separate namespace is just providing a backdoor that everyone needs to use, defeating the point of using a separate namespace.
