[Libguestfs] guestfish hang when exec command.

Hi, I have some issues with libguestfs. I download the libguestfs-0.18.3 source code and read the README file. it requested qemu >= 0.13, my qemu version is qemu-1.0.1 requested kernel version >= 2.6.34, my kernel version is 3.1.4 the most of requirement for compiling I reached. but I completed compiltion and executed command. the guestfish hang there. the following was my operating steps: tar -Jxvf appliance-<VERSION>.tar.xz Then copy all four files: * kernel * initrd * root * README.fixed into a directory somewhere, eg. /usr/local/lib/guestfs/appliance/ Then build libguestfs (>= 1.16.7 or >= 1.17.10) from source, disabling the normal appliance and daemon: ./configure --disable-appliance --disable-daemon make make install Set LIBGUESTFS_PATH to the path where you unpacked these files, eg: export LIBGUESTFS_PATH=/usr/local/lib/guestfs/appliance/ then executed command: virt-copy-out -d GuestName 'win:c:\windows\system32\config' . the command hang here. Is there something going wrong? give me some help, thanks! xuanmao_001
