Comment 3 David Hill 2019-10-06 17:43:50 UTC

I get the same behavior with this command:
/usr/bin/virt-sysprep -v -x -a /var/lib/jenkins/VMs/undercloud-0-rhosp13.qcow2

Is supermin the problem ?

Comment 4 Richard W.M. Jones 2019-10-06 17:48:51 UTC

It's probably this kernel bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1758413

(Setting bug priority has no effect except to make everyone annoyed)

Comment 5 David Hill 2019-10-06 18:28:37 UTC

I can confirm you that reverting to a 5.3.2 kernel solves this problem ...

Comment 6 Richard W.M. Jones 2019-10-06 18:37:40 UTC

Thanks for testing this.  I will mark this bug as duplicate of
the other one.
