From http://mirror.centos.org/centos/7/os/x86_64/Packages/ site, I can find qemu-kvm rpm package.

And I want to see the source code of qemu-kvm for this package, where can I find it?

From the package name 'qemu-kvm-1.5.3-86.el7.x86_64.rpm', the qemu version is 1.5.3.

Are the source code just the same as code from site  http://git.qemu.org/ with 1.5.3 tag?

Regards,

Jackie
