Description Hu Zhang 2015-05-25 10:07:27 UTC

Description of problem:
virt-resize/virt-build/virt-sysprep/virt-customize fail to execute and return the error "Segmentation fault (core dumped)". It works well on ppc64be machine.

Version-Release number of selected component (if applicable):
libguestfs-1.28.1-1.35.ael7b.ppc64le
libguestfs-tools-c-1.28.1-1.35.ael7b.ppc64le
kernel-3.10.0-244.ael7b.ppc64le

How reproducible:
Always

Steps to Reproduce:
1. On a ppc64le machine.
# virt-resize RHEL-Server-6.7-64-hvm.raw test1.img -v -x
command line: virt-resize RHEL-Server-6.7-64-hvm.raw test1.img -v -x
Examining RHEL-Server-6.7-64-hvm.raw ...
libguestfs: trace: set_verbose true
libguestfs: trace: set_verbose = 0
Segmentation fault (core dumped)

2. On a ppc64le machine.
# virt-customize -a RHEL-Server-6.7-64-hvm.raw --hostname rhel -x -v
[   0.0] Examining the guest ...
libguestfs: trace: set_verbose true
libguestfs: trace: set_verbose = 0
libguestfs: trace: set_network true
libguestfs: trace: set_network = 0
libguestfs: trace: set_selinux false
libguestfs: trace: set_selinux = 0
Segmentation fault (core dumped)

For virt-build and virt-sysprep, it returns the same error info.

Actual results:
Described as above.

Expected results:
virt-resize/virt-build/virt-sysprep/virt-customize should work well with no error return.

Comment 2 Richard W.M. Jones 2015-05-28 20:26:54 UTC

This appears to be the same root cause as bug 1224675, which
would mean this bug should depend on 1225995.  However I
will wait until I have all acks on 1225995 and can rebuild
the OCaml compiler + libguestfs.

Comment 3 Richard W.M. Jones 2015-05-29 09:45:32 UTC

I've now confirmed this has the same root cause as bug 1224675
and bug 1225995.

Comment 5 Hu Zhang 2015-09-14 05:33:34 UTC

Verified with the packages:
libguestfs-1.28.1-1.54.el7.ppc64le
libguestfs-tools-c-1.28.1-1.54.el7.ppc64le

Verify step:
1. On a ppc64le machine.
# virt-resize RHEL-Server-6.7-64-hvm.raw test1.img -v -x
...
Resize operation completed with no errors.  Before deleting the old disk, 
carefully check that the resized disk boots and works correctly.

2. On a ppc64le machine.
# virt-customize -a RHEL-Server-6.7-64-hvm.raw --hostname rhel -x -v
# guestfish -a RHEL-Server-6.7-64-hvm.raw -i cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=rhel

Commands work as expected. So verified.
