Comment 1 Richard W.M. Jones 2012-11-29 11:48:59 UTC

Upstream fix here:
https://github.com/libguestfs/libguestfs/commit/9e7daf2ee8f0a619440ca1c55dfe5ddcf61b4460

Comment 2 Richard W.M. Jones 2012-11-29 11:50:10 UTC

The upstream fix will be included in libguestfs 1.20
which is what we are planning to settle on in RHEL 7,
so likely no further dev action is required for this bug.

Hi Rich,
I try to reproduce it with libguestfs-1.20.1-4.el7 but it works well with libguestfs-1.20.1-4.el7(It has the seem result as libguestfs-1.22.6-15.el7). So, in order to reproduce it I need to install libguestfs-1.18.* or libguestfs-1.19.*, but I found it is difficult to solve the dependence. It seems libguestfs has a big change after libguestfs-1.19, I have spent time on it but failed.  So I just verified it.  Is it proper to do so? 


The following are the steps to verify it:

1. Prepare two guest image: rhel guest & Windows guest
2. #virt-df -a RHEL-Server-6.5-64-hvm.raw2  -a Win2008r2-64-hvm.raw
Filesystem                           1K-blocks       Used  Available  Use%
RHEL-Server-6.5-64-hvm.raw2+:/dev/sda1
                                        487652      26680     431276    6%
RHEL-Server-6.5-64-hvm.raw2+:/dev/sdb1
                                      15359996    8181024    7178972   54%
RHEL-Server-6.5-64-hvm.raw2+:/dev/VolGroup/lv_root
                                       6795192    1493268    4933696   22%


===> virt-df works well. 


Thanks & Best Regards

This was fixed in 1.19.65, so as you say you would have to
install some very old version of libguestfs to reproduce the
bug, and I think that will be impossible.

I think you should just check (as you have done) that the problem
is fixed in the latest package.  There's no need to try reproducing
something which wasn't ever a bug in RHEL 7.

Verified it with libguestfs-1.22.6-17.el7


Steps to verify it:
1. Prepare two guest image: rhel guest & Windows guest
2. #virt-df -a RHEL-Server-6.5-64-hvm.raw -a Win2008r2-64-hvm.raw 
Filesystem                           1K-blocks       Used  Available  Use%
RHEL-Server-6.5-64-hvm.raw+:/dev/sda1
                                        487652      26665     431291    6%
RHEL-Server-6.5-64-hvm.raw+:/dev/sdb1
                                      15359996    8181024    7178972   54%

So, bug is fixed.
