[Qemu-discuss] qemu-kvm and qemu-system-x86_64

My situation: I want to run a KVM-accelerated qemu but I want to build 
everything involved from the latest sources and use those instead of any 
downloadable distro packages.  (This is on SLES12-SP3 although I don't think 
the distro matters).

I am able to build and install from 
   * http://github.com/qemu/qemu using  ../configure 
--target-list=x86_64-softmmu --enable-kvm --prefix=/usr --sysconfdir=/etc
   * http://github.com/libvirt/libvirt  using ./configure --prefix=/usr 
--sysconfdir=/etc --localstatedir=/var

Before running make install,  I also removed the existing distro packages like 
libvirt, libvirt-client, qemu-kvm, etc.

My  question:  In the installed distro packages there was an executable, 
But after building and installing qemu from sources as above, I did not see any 
new qemu-kvm.
Is there some other repository I need to build from to get qemu-kvm? 

I ask because I am starting vms using virsh define xyz.xml; virsh start xyz.  
And in the original .xml files I had the following under devices:

Can I replace that with 

And given that I am already using
        <boot dev="hd"></boot>

Will I get the same KVM acceleration as I was previously getting by using
