Libguestfs - Jul 2014 - Re: 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.

Yes, sorry, this is a known bug in the CentOS 7 libguestfs package.

See:

  https://www.redhat.com/archives/libguestfs/2014-July/msg00036.html

for a couple of workarounds.

Karanbir, should I file a bug about this?

yes please.

I'm guessing this is a fall out of how the centos-release package is
setup, but lets look. a bugreport would be good.
