Hello.

thanks. I tried,but it didn't work :

root at zi-desktop:~/Desktop/zi/Work/I9/libvirt/libvirt_build/usr/bin# export
PYTHONPATH=$PYTHONPATH:/home/zi/Desktop/Work/I9/libvirt/libvirt_build/usr/share/virt-manager

root at zi-desktop:~/Desktop/zi/Work/I9/libvirt/libvirt_build/usr/bin# ls
/home/zi/Desktop/Work/I9/libvirt/libvirt_build/usr/share/virt-manager

icons  ui  virtinst  virtManager

root at zi-desktop:~/Desktop/zi/Work/I9/libvirt/libvirt_build/usr/bin#
virt-manager

Traceback (most recent call last):
