Several things -

In the qemu 0.10 series in general, we need the upstream vmchannel
support:
http://lists.gnu.org/archive/html/qemu-devel/2009-02/msg01042.html

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.
