Hi Jun,
I assume you haven't changed libvirt default URI, it may be a issue,
I want to know whether it works for you if you explicitly specify
--connect qemu:///system with virt-install? I think a root reason
probably is your disk image location, the log said it can't find
storage volume, if you put img.winp under the /var/lib/libvirt/images,
then give a disk absolute path to virt-install, Does it work for you?
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:

A very common cause of this problem is that a systemwide instance of
dnsmasq is already (erroneously) listening on the bridge created by
libvirt for the default network.
Laine, yeah, I'm missing this important reason.
I took your email as an oppurtunity to
write an entry in the new Troubleshooting section of the libvirt wiki.
It will explain to you how to solve your problem (*if* this is your
problem, of course :-).

Great, I want to tidy up a doc about this ago, it should be very helpful for a new guys.

Thanks & Regards,
Alex
If that ends up not being your problem, please reply to this message,
but sending the reply to libvirt-users@xxxxxxxxxx (I also Cc'ed this
message there) rather than to libvir-list@xxxxxxxxxx. (The former is the
official list for user questions about libvirt, whil libvir-list is
intended for for people discussing the code.)


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?
The "default" network should already be there as part of the stock install.
