IMHO blaming anybody for it but qemu maintainership is very unfair. They intentionally reinveinted a less self contained, inferior, underperforming, underfeatured wheel instead of doing the right thing and just making sure that it as self contained enough as possible to avoid risking destabilizing their existing codebase. What can anybody (without qemu git commit access) do about it unless qemu git maintainer change attitude, dumps its qemu/kvm-all.c nosense for good, and do the right thing so we can unify for real? We need to move forward, including multithread the qemu core and be ready to include desktop virtualization protocol when they're ready for submission without being suggested to extend vnc instead to gain a similar speedup (i.e. yet another inferior wheel). Unification means that _all_ qemu users, pure research, theoretical interest, Xen, virtualbox, weird pure software architecture, will be able to push their stuff in for the common good, but that also shall apply to KVM! It has to become clear that reinveinting inferior wheels instead of merging the real thing, is absolutely time wasteful, unnecessary, and it won't make any difference as far as KVM is concerned, proof is that 0% of userbase runs qemu git to run KVM (except the kvm-all.c developers to test it perhaps or somebody by mistake not adding -kvm prefix to command line maybe). I don't pretend to rate KVM as more important than all the rest of niche usages for qemu but it shall be _as_ important as the rest and it'd be nice one day to be able to install only qemu on a system and get something actually usable in production. I very much like that qemu gets contributions from everywhere, it's also nice it can run without KVM (that is purely useful as a debugging tool to me but still...). I think it can all happen and unification should be the object for the gain of everyone in both qemu/kvm and even xen and all the rest. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
