Several things -

In the qemu 0.10 series in general, we need the upstream vmchannel

qemu 0.10.4 wouldn't even boot the libguestfs appliance.  For whatever
unknown reason it does appear that qemu 0.10.5 fixes this.  I don't
know what particular change fixes this.

Generally KVM works, again specific versions sometimes have problems.

Really the best thing to do is to run 'make check' [or for EPEL,
'make SUBDIRS= check'] and if that passes then the qemu/kvm version
is good.
