Ok, I installed the rpms, and tried to start an old F16 guest, and then tried to create a
'new' guest w/ 'pxe' option. This is what I see:

##################################################################
[root at foobar qemu-and-ipxe-rpms]# virsh start f16t1
error: Failed to start domain f16t1
error: internal error cannot parse /usr/bin/qemu-kvm version number in 'QEMU emulator
version 1.0 (qemu-kvm-1.0), Copyright (c) 2003-2008 Fabrice Bellard'

[root at foobar qemu-and-ipxe-rpms]#
##################################################################
[root at foobar qemu-and-ipxe-rpms]# rpm -qa | grep -i qemu
ipxe-roms-qemu-20120328-1.gitaac9718.fc16.noarch

qemu-kvm-1.0-11.fc16.x86_64

qemu-img-1.0-11.fc16.x86_64
[root at foobar qemu-and-ipxe-rpms]#
##################################################################

And, then try to create a new guest w/ 'pxe' using virt-install
##################################################################
[root at foobar pxetest]# ./pxetest1.bash
+ virt-install --connect=qemu:///system --network=bridge:br0 --pxe --name f16tbox2 --disk
path=/var/lib/libvirt/images/f16tbox2.img,size=8 --ram 1024 --vcpus=2 --check-cpu --hvm
--os-variant fedora16
ERROR    Host does not support virtualization type 'hvm'
##################################################################
[root at foobar pxetest]# file /dev/kvm
/dev/kvm: character special
[root at foobar pxetest]#
##################################################################

(Side note: the above same virt-install cmd-line worked for me using gpxe ont this same box)

Any hints?
