escription of problem:
Can't convert rhel6.8 x86-lpfc host by virt-p2v


Version-Release number of selected component (if applicable):
libvirt-2.0.0-4.el7.x86_64
libguestfs-1.32.6-5.el7.x86_64
qemu-kvm-rhev-2.6.0-18.el7.x86_64
virt-v2v-1.32.6-5.el7.x86_64
virt-p2v-1.32.6-5.el7.x86_64


How reproducible:
50%

Steps to Reproduce:
1.Install rhel6.8 x64 on lpfc storage which has one road,  pls refer to screenshot fc-one-road, besides machine (IBM-x3755-04)could boot into os after installation, check os info as below
1.1 # uname -a

2.Boot the machine into p2v client via pxe
3.Input conversion server info and click "next"
4.Input conversion info and then click"start conversion" to convert host
5.Conversion will be failed with virt-v2v: error: no kernels were found in the grub configuration, details pls refer to details log


Actual results:
As above description

Expected results:
Could convert rhel6.64-lpfc host by virt-p2v successfully

Additional info:
1.Can reproduce this problem on another lpfc machine(hp460cg1-01) which has fc storage with one road
2.Can't reproduce this problem on another lpfc machine(hp460cg1-02) which has fc storage with double road, pls refer to screeshot fc-double-road

Comment 5 mxie@redhat.com 2016-08-23 06:02:57 UTC
I also could reproduce this bug when convert rhel6.8-MD host by virt-p2v with builds:
libvirt-2.0.0-5.el7.x86_64
virt-p2v-1.32.7-2.el7.x86_64
libguestfs-1.32.7-2.el7.x86_64
virt-v2v-1.32.7-2.el7.x86_64
qemu-kvm-rhev-2.6.0-21.el7.x86_64
virtio-win-1.8.0-5.el7.noarch

I think this bug is related to package "tboot-1.8.3-2.el6.x86_64.rpm " because the conversion will be finished without error if not select tboot package during installing rhel6.8 on MD

Comment 7 Richard W.M. Jones 2017-02-16 14:33:22 UTC
Sorry for some reason this bug dropped off the radar.

I think you are right that the conversion failed because of the
use of tboot (which I'd never heard of up til now).  Updating the
summary to reflect this.

Comment 8 Richard W.M. Jones 2017-02-16 14:47:08 UTC
I was trying to work out a reproducer for this, but I can't quite work
it out.  Simply installing tboot is not sufficient to reproduce it.

Comment 9 Richard W.M. Jones 2017-03-28 14:29:31 UTC
Out of development time for RHEL 7.4.  Moving to RHEL 7.5.

Comment 11 Richard W.M. Jones 2019-05-13 10:16:58 UTC
We're not planning any more work on virt-p2v in RHEL 7 once 7.7 is released.
If this issue occurs in RHEL 8, please open a new bug about it.
