Description of problem:
Failed to restart network service after converting rhel6 guest from disk by virt-v2v 

Version-Release number of selected component (if applicable):
libguestfs-1.36.3-4.el7.x86_64
virt-v2v-1.36.3-4.el7.x86_64
qemu-kvm-rhev-2.9.0-8.el7.x86_64
libvirt-3.2.0-7.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Prepare a rhel6 guest whose network name is eth0 and network serivce could be restarted successfully

2.Using virt-v2v to convert this guest from disk to rhv
# virt-v2v -i disk xen-pv-rhel6.9-x86_64-sda -o rhv -os 10.73.131.93:/home/nfs_export -if qcow2
[   0.0] Opening the source -i disk -if qcow2 xen-pv-rhel6.9-x86_64-sda
[   0.0] Creating an overlay to protect the source from being modified
[   0.1] Initializing the target -o rhv -os 10.73.131.93:/home/nfs_export
[   0.4] Opening the overlay
[   1.5] Inspecting the overlay
[  11.3] Checking for sufficient free disk space in the guest
[  11.3] Estimating space required on target for each disk
[  11.3] Converting Red Hat Enterprise Linux Server release 6.9 (Santiago) to run on KVM
virt-v2v: warning: /files/boot/grub/device.map/hd0 references unknown 
device "vda".  You may have to fix this entry manually after conversion.
virt-v2v: warning: /files/etc/sysconfig/grub/boot references unknown device 
"vda".  You may have to fix this entry manually after conversion.
virt-v2v: This guest has virtio drivers installed.
[  85.7] Mapping filesystem data to avoid copying unused and blank areas
[  85.8] Closing the overlay
[  86.0] Checking if the guest needs BIOS or UEFI to boot
[  86.0] Assigning disks to buses
[  86.0] Copying disk 1/1 to /tmp/v2v.kMgJ6I/4f699f1d-7f77-4e73-a0d2-a3b73c1a0c29/images/af8b2af7-57a4-43ee-9a2f-f6e63525a785/325b50b7-6db3-43d3-9a52-d69649cf0110 (qcow2)
    (100.00/100%)
[ 147.4] Creating output metadata
[ 147.5] Finishing off

3.After finishing conversion, import the guest from data domain to export domain
4.Power on the guest, but find the network name is changed to eth1 and failed to restart network service, pls refer to screenshot "rhel6-convert-from-disk" and log "rhel6-convert-from-disk"


Actual results:
As above description

Expected results:
Restart network service successfully after converting rhel6 guest from disk by virt-v2v

Also failed to restart network service after converting rhel6 guest from ova by virt-v2v , details pls refer to log
#virt-v2v -i ova esx5.5-rhel6.8-x86_64.ova -of qcow2 -v -x |& tee > virt-v2v-ova.log

Comment 4 Jaroslav Suchanek 2020-01-23 10:11:13 UTC
The '-i disk' does not provide enough metadata for v2v. This cannot be fixed.
