[Libguestfs] febootstrap error ?



hi,

i am not quite sure about the below error:

[ 1320.506848] INFO: task init:1 blocked for more than 120 seconds.
[ 1320.510069] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs"
disables this message.

The below commands

guestmount,
virt-*

either hangs or taking a gazillion time to finish (not correctly).

I've attached a file with two cases

In both cases, in tmp folder there are:

[ebal mylaptop tmp]€ tree libguestfsj5tGtJ/
libguestfsj5tGtJ/
└── guestfsd.sock

0 directories, 1 file
[ebal mylaptop tmp]€ tree libguestfsMRArh2
libguestfsMRArh2
└── guestfsd.sock

0 directories, 1 file

after the processes are hanged

libguestfs 1.14.7
febootstrap 3.12
qemu-kvm 1.0
augeas 0.10.0
hivex 1.3.3
libvirt 0.9.8

[root mylaptop ~]# uname -r
3.1.4-1-ARCH

any ideas ?
