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.

thanks so much, Alex. it works for me now! it turns out i uninstalled the dnsmasq, but it seems there is dependency on it (why we need dnsmasq, anyway?). so i reinstalled it again, but then disable dnsmasq service. then the default virtual network works. a quesiton: i imported the existent KVM image with command: virt-install --connect qemu:///system -n winxp -r 800 --accelerate --vnc -v --noautoconsole --import -f /home/jun/img/img.winxp but this is not really correct, as the above command doesnt do something for me: (1) it doesnt tell the image format (qcow2 in my case) (2) it doesnt setup the mouse cursor (-usb -usbdevice tablet) (3) it doesnt tell the network card model. so questions are: (1) can i tell virt-install of of above info? i looked at the virt-install manual, but dont see anywhere to do that. (2) in case virt-install cannot do that, i guess i must use another tool to modify /etc/libvirt/qemu/winxp.xml to reflect my requirement. but then i tried virt-manager (0.9.1), and it doesnt even let me modify the configuration of my domain. so which tool should i use to modify available libvirt domain? thanks again!

so i reinstalled it again, but then disable dnsmasq service. then the default virtual network works.
a quesiton: i imported the existent KVM image with command:
virt-install --connect qemu:///system -n winxp -r 800 --accelerate --vnc -v --noautoconsole --import -f /home/jun/img/img.winxp
but this is not really correct, as the above command doesnt do something for me:
(1) it doesnt tell the image format (qcow2 in my case) Libvirt doesn't autodetect storage format due to potential security issue, so you need to explicitly specify 'format' to qcow2, otherwise, defaults to raw format, for example: % virt-install --connect qemu:///system -n winxp -r 800 --accelerate --vnc -v --noautoconsole --disk /home/jun/img/img.winxp,format=qcow2 --import
(2) it doesnt setup the mouse cursor (-usb -usbdevice tablet)
(3) it doesnt tell the network card model. There are some default value for these, please see virt-install man page carefully. so questions are:
(1) can i tell virt-install of of above info? i looked at the virt-install manual, but dont see anywhere to do that. Yes, you can, see 'Device Options' and 'Networking Configuration'
For details, please see virt-install man page. section in man page.
(2) in case virt-install cannot do that, i guess i must use another tool to modify /etc/libvirt/qemu/winxp.xml to reflect my requirement. but then i tried virt-manager (0.9.1), and it doesnt even let me modify the configuration of my domain.
so which tool should i use to modify available libvirt domain? If you only want to modify domain configuration, virsh edit should be enough, libvirt provides a group of users layer virsh commands, you may also use virsh commands to operate libvirt such as installation a guest.
