[Libguestfs] virtdf outputs on host differs from df in guest

[陈帆]

after install libguestfs_xfs,  all results are:



[using guestfish]
guestfish -N fs:xfs -m /dev/sda1 statvfs /
bsize: 4096
frsize: 4096
blocks: 24713
bfree: 23391
bavail: 23391
files: 51136
ffree: 51133
favail: 51133
fsid: 2049
flag: 4096
namemax: 255


[using virt-rescure]
virt-rescue -a test1.img
><rescue> mount /dev/sda1 /sysroot
><rescue> stat -f /sysroot
  File: "/sysroot" 
    ID: 80100000000 Namelen: 255     Type: xfs
Block size: 4096       Fundamental block size: 4096
Blocks: Total: 24713      Free: 23391      Available: 23391
Inodes: Total: 51136      Free: 51133


the free numbers are the same. but the "virt-df" output is not changed.


Thanks,
Chen
