ok, i change the command a bit, and it went further.
here is how i did:

(1) compiled everything from source, then install (make install) to my Ubuntu

(2) start libvirtd on commandline
# libvirtd -d

(3) import my KVM image to libvirt

$ virt-install --connect qemu:///system -n winxp -r 800 --accelerate
--vnc -v --noautoconsole --import -f /home/jun/img/img.winxp

it failed, and the log is like below:

....

i guess perhaps just starting "libvirtd -d" on commandline is not
enough. do i need a script to configure and start libvirtd properly
for me?
and it seems i must configure the virtual network somehow?

currently, the output of brtctl is like below:

$ brctl show
bridge name	bridge id		STP enabled	interfaces
pan0		8000.000000000000	no		



thanks,
