There's nothing to fix - this is simply a deployment issue - the default
installation we provide sets up a 'default' virtual network which provides
guests with a NAT based network connection out of the box which requires
bridgeutils. If you don't want to use that then you can remove this default
config from /etc/libvirt/qemu/networks. All the QEMU network configs without
use of bridge-utils are pretty crap though, hence why we setup this default
networking config for people

Debug it with 'virsh' first to make sure the basic functionality is working
and then go onto virt-install.
Yes, virsh works well: it returns few pages of xml data.
However, "virt-install" still has problem like below. It seems to have
some thing with Xen? I dont install Xen on my machine.
Could you give some hints to fix this??
Thanks,
