Description of problem:

Although the virt-v2v convert the rhel7.2 to qcow seems to success, there are some error appeal.And in the openstack,the qcow2 convert to instance failed(can not ping or ssh it,but rhel6.2、centos6.5 and windows successed), 

environment:

virt-v2v-1.32.7-1.el7.x86_64

libguestfs-1.32.7-1.el7.x86_64

get them from yum : http://people.redhat.com/~rjones/libguestfs-RHEL-7.3-preview

source os: rhe17.2

Additional info:
I guess maybe the /sysroot/selinux should be exist?
Comment 2 Richard W.M. Jones 2016-09-13 08:52:25 UTC 
It appears this is just a warning:

Can't stat exclude path "/sysroot/selinux", No such file or directory - ignoring                    .
libguestfs: trace: v2v: selinux_relabel = 0

The selinux_relabel command returned successfully.

If the conversion failed, please include the *complete*, *unedited*
log from virt-v2v -v -x.

If the conversion is success, then you can close this as it is not a bug.
Comment 3 laitao 2016-09-14 02:27:06 UTC 
yes,the conversion is success,the error should be ingored,something wrong with the openstack,and it is fixed.
