RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 1 Richard W.M. Jones 2018-07-27 06:56:15 UTC 
[    1.125231] init[1]: segfault at 0 ip 00007f0e44c00f80 sp 00007ffc77e7f590 error 4 in libc-2.17.so[7f0e44b92000+1c3000]

The supermin init process segfaults, which is not good.
Comment 3 Richard W.M. Jones 2018-07-27 06:56:43 UTC 
What is the version of supermin?
Comment 4 zhujinhe 2018-07-27 06:59:57 UTC 
[root@rg1-ceph1 ~]# rpm -qa | grep supermin
supermin5-5.1.19-1.el7.x86_64
Comment 5 Richard W.M. Jones 2018-07-27 08:03:33 UTC 
Unfortunately I cannot reproduce this locally using CentOS 7 and
the same package versions.  Are you using qemu-kvm or qemu-kvm-ev,
and which version?
Comment 6 Richard W.M. Jones 2018-07-27 08:06:55 UTC 
Since I cannot reproduce this I can only make broad suggestions
about what you might try to do:

(1) Remove /var/tmp/.guestfs-* and run libguestfs-test-tool.  Does
the same problem happen after this?

(2) Download a pre-built appliance from
http://download.libguestfs.org/binaries/appliance/appliance-1.36.1.tar.xz
unpack it somewhere, set LIBGUESTFS_PATH to point to that directory
and run libguestfs-test-tool.  Does this fix it?

(3) Try building supermin and/or libguestfs from source and see if either
of those fixes it.

Comment 7 Richard W.M. Jones 2018-07-27 08:11:29 UTC 
Another thing you could try is to resolve libc-2.17.so[7f0e44b92000+1c3000]
into an actual symbol.  It would certainly help to know which
function in libc is crashing.

Comment 8 zhujinhe 2018-07-27 11:27:42 UTC 
I'm using a custom kernel which seems to be a suspect.
Is there a way to use a specified kernel, in this case vmlinuz-3.10.0-327.4.5.el7.x86_64?

Comment 9 Richard W.M. Jones 2018-07-27 11:37:23 UTC 
Yes a custom kernel could well cause this.  You can select a specific
kernel by doing:

export SUPERMIN_KERNEL=/boot/vmlinuz-3.10.0-327.4.5.el7.x86_64
export SUPERMIN_MODULES=/lib/modules/3.10.0-327.4.5.el7.x86_64
export SUPERMIN_KERNEL_VERSION=3.10.0-327.4.5.el7.x86_64
rm -rf /var/tmp/.guestfs-*
libguestfs-test-tool

Note the 'rm' command is required, else the appliance doesn't get
rebuilt.

I don't know, suggest looking at comments 5-7 again.  You could also
try compiling your own qemu and using that.
Comment 13 zhujinhe 2018-07-27 13:08:58 UTC 
This does fix the problem.
(2) Download a pre-built appliance from
http://download.libguestfs.org/binaries/appliance/appliance-1.36.1.tar.xz
unpack it somewhere, set LIBGUESTFS_PATH to point to that directory
and run libguestfs-test-tool.  Does this fix it?

Thanks so much Richard W.M. Jones.

Closing since the reporter found a workaround but we never
got to the bottom of why it is broken in the first place.
