libvirt-daemon itself creates the qemu user on Fedora:
%if %{with_libvirtd}
%pre daemon
%if 0%{?fedora} >= 12 || 0%{?rhel} >= 6
# We want soft static allocation of well-known ids, as disk images

# https://fedoraproject.org/wiki/Packaging:UsersAndGroups
getent group kvm >/dev/null || groupadd -f -g 36 -r kvm
getent group qemu >/dev/null || groupadd -f -g 107 -r qemu
if ! getent passwd qemu >/dev/null; then
if ! getent passwd 107 >/dev/null; then
useradd -r -u 107 -g qemu -G kvm -d / -s /sbin/nologin -c "qemu
user" qemu
else
useradd -r -g qemu -G kvm -d / -s /sbin/nologin -c "qemu user" qemu

That sounds like an independently useful suggestion regardless of how
you resolve the user creation issue - we've already had recent patches
to reduce the dependencies of libvirt-daemon by pushing Requires: lines
into the respective hypervisor packages.
