Libguestfs - Dec 2016 - Re: [rhev-tech] virt-v2v failure during selinux re-lable

Reaching out to libguestfs@redhat.com.  Thanks Shahar, I didn't know that
email alias existed.  Also, I made the XML, full logs, and sosreport from
the VM in question available here [1]

The bug is likely to be this one:

  https://bugzilla.redhat.com/show_bug.cgi?id=1374232

Assuming the root cause is the same thing, there is a workaround in
the bug, see comment 7.  It requires a small edit inside the guest
before starting the conversion.

We're going to fix this properly in RHEL 7.4

HTH,

Rich.
