Libguestfs - Nov 2019 - Re: virt-df -a xxx.qcow2 failure, after about ten minutes , failed

use the virt-df to query vm disk usage like this:
virt-df -a /home/centos7_mini.qcow2
then check:
virsh list --all
Id Name State

1 guestfs-p1km7lhfowv8o0q1running //virt-df will create a vm in temp filesystem

but after a few minutes , still fails to get the vm disk usage , why ??
