Thanks again, but when I run the command "sudo update-guestfs-appliance"

the result is "unpacking /tmp/superminef3fb7da4d1971287149691a8361ae0d.tmp/syslinux_3%3a4.05+dfsg-6+deb8u1_amd64.deb ...

but when I run "virt-df -d `virsh domuuid 5` "

the errors are also still ,

incito@M06MYPY9:~$ virt-df -d `virsh domuuid 5`
libguestfs: warning: supermin-helper -f checksum returned a short string
libguestfs: error: cannot find any suitable libguestfs supermin, fixed or old-style appliance on LIBGUESTFS_PATH (search path: /usr/lib/guestfs)
incito@M06MYPY9:~$

But I find another solution, I use “sudo virt-df -d `virsh domuuid 5`" , and set the user without password （/etc/sudoers) to run the command .

I'll assume this is an old Ubuntu version, in which case you need to

run:

sudo update-guestfs-appliance

See: http://libguestfs.org/guestfs-faq.1.html#libguestfs:-error:-cannot-find-any-suitable-libguestfs-supermin-fixed-or-old-style-appliance-on-libguestfs_path

This is not required in newer versions of libguestfs.
