[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!

The build process looks fine.  However please run libguestfs-test-tool
in order to debug things:

  export LIBGUESTFS_PATH=/usr/local/lib/guestfs/appliance/
  libguestfs-test-tool

Post the *complete, unedited* output here.

Rich.

[Libguestfs] guestfish hang when exec command.

This version of seabios contains an alignment bug that causes accesses
to virtio-blk devices to hang.  It is fixed by this patch:

http://anonscm.debian.org/gitweb/?p=pkg-qemu/seabios.git;a=commitdiff;h=3c5fcec00ce1317cda56d549259550fcc018c834

but I would suggest updating seabios to a more recent version since
this version is very old and probably has other bugs.

Rich.
