Is there any qemu portage developer here?

I am using qemu (non-kvm specific) through app-emulation/qemu

On 22/10, the ebuild is changed from source qemu (non-kvm specific) to qemu-kvm http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/app-emulation/qemu/qemu-1.2.0.ebuild?view=log


Why take this change :?:
The upstream is trying to merge kvm into qemu, all new patches goes into qemu git.
why gentoo developer moves in the opposite direction?

What is the ebuild of qemu (non-kvm specific) now?

Actually, I think you got a bit confused as to which way the ebuilds went. It did make for confusion, but we got through it.

The app-emulation/qemu-kvm ebuild left the tree on October 10 because they merged it with app-emulation/qemu. I know that date well: it came as a surprise to me as I was doing an upgrade. The kvm USE flag went away when they made the change. I suppose that's because hooking into the kernel to get KVM support must be awfully trivial. The -enable-kvm switch is what actually tells the qemu binary to use KVM--leave off the switch, and you still get the soft emulation you were using. The convenience script qemu-kvm is still there to invoke the qemu binary with the -enable-kvm switch, just as it did in the old qemu-kvm package.

All it takes to get KVM, assuming you're running an x86 host, is to be sure that you have the qemu_softmmu_targets_x86_64 USE flag. (I suppose that for other architectures where the kernel has KVM support, that you get KVM support in the respective qemu builds.)

So, the change in Gentoo was just the opposite of what you were afraid it was. Just as the upstream has done, Gentoo has merged the separate qemu-kvm package into the main qemu package. There are plenty of things to worry about; this doesn't have to be one of them :)

i take a look at qemu-9999.ebuild http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/app-emulation/qemu/qemu-9999.ebuild?revision=1.32&view=markup

it is still pointing to kvm git git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git, not qemu git "git.qemu.org/qemu.git"

In that case, please file a bug at https://bugs.gentoo.org :)
