[Libguestfs] File not found by ext2_lookup

Hello, I've been trying to clone one disk image (LVM) to another using virt-resize. Unfortunately I get the following error: # virt-resize /dev/vm/vm6 /dev/vm/vm7 supermin helper [00004ms] finished creating kernel supermin helper [00251ms] finished mke2fs <domain type='kvm'> supermin helper [00252ms] visiting /usr/lib64/guestfs/supermin.d supermin helper [00252ms] visiting /usr/lib64/guestfs/supermin.d/base.img.gz supermin helper [03505ms] visiting /usr/lib64/guestfs/supermin.d/daemon.img.gz supermin helper [03527ms] visiting /usr/lib64/guestfs/supermin.d/hostfiles libguestfs: trace: launch = -1 (error) Fatal error: exception Guestfs.Error("supermin-helper exited with error status 1, see debug messages above") libguestfs: trace: close Is there any known issue that could cause this? I have CentOS 7.0.1406 at the host node at CentOS 6.5 at the guest. Thanks.
