Hi Rich,
I got an odd error, can you help me with this error
or give me a debug method?

Thanks,
Wanlong Gao

I think in general the patch is looking good.  Is does however
really need a test, and it should be possible to add one using
something like this (untested):

  tests = [
    InitEmpty, IfAvailable "xfs", TestOutputStruct (
        [["part_disk"; "/dev/sda"; "mbr"];
         ["mkfs"; "xfs"; "/dev/sda1";
""; "NOARG"; ""; ""];
         ["mount_options"; ""; "/dev/sda1";
"/"];
         ["xfs_info"; "/"]],
        [CompareWithInt ("blocksize", 4096);
         (* other comparisons here if you want *)
        ]);
  ]

(NB This requires the mkfs-opts -> mkfs patch that I posted on
the mailing list on Saturday, but which is not upstream)

What is the odd error that you are seeing?  For debugging, just print
stuff out, as you are doing, and then run the program using
LIBGUESTFS_DEBUG=1.

Rich.

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
http://et.redhat.com/~rjones/virt-top

Add xfs_info to show the geometry of the xfs filesystem.
