Ah, that is the problem. Your /usr/bin/qemu-system-x86_64 binary only supports
the above machine types but domain XML wants rhel5.4.0 machine type. Did you
install qemu from an unofficial package or something like that? Since normally
it supports rhel5.4.0 and the binary is called /usr/libexec/qemu-kvm. If you
really want to use the /usr/bin/qemu-system-x86_64 binary, you need to make
virt-install use "pc" machine type since by default it doesn't use any and
libvirt 0.6.3 selects rhel5.4.0 as a default (newer libvirt versions are more
clever in this). However, virt-install doesn't seem to have an option which
could be used for overriding machine type :-/ You would need to change the
type element in domain XML from
    <type arch='x86_64'>hvm</type>
to
    <type arch='x86_64' machine='pc'>hvm</type>

The easiest fix is to use the /usr/libexec/qemu-kvm binary, which is provided
by kvm package.
