Description
virt-v2v will fail when converting guests with initramfs-*kdump.img under /boot

Version:
libguestfs-tools-c-1.27.32-1.1.el7.x86_64
libguestfs-1.27.32-1.1.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Prepare a guest installed kdump,there is initramfs-*kdump.img under /boot.
# cd /boot
# ls |grep initramfs-3.10.0-123.el7
initramfs-3.10.0-123.el7.x86_64.img
initramfs-3.10.0-123.el7.x86_64kdump.img

2.Run virt-v2v to convert the guest,error shows and virt-v2v fails.
# virt-v2v -o rhev -os 10.66.90.115:/vol/v2v_auto/auto_export --network rhevm rhel7-http
[   0.0] Opening the source -i libvirt rhel7-http
[   0.0] Creating an overlay to protect the source from being modified
[   0.0] Opening the overlay
[   9.0] Initializing the target -o rhev -os 10.66.90.115:/vol/v2v_auto/auto_export
[   9.0] Inspecting the overlay
[  16.0] Converting Red Hat Enterprise Linux Server release 7.0 (Maipo) to run on KVM
virt-v2v: error: multiple files in /boot could be the initramfs
matching kernel 3.10.0-123.el7.  This could be a bug in virt-v2v.


virt-v2v: If reporting bugs, run virt-v2v with debugging enabled (-v
-x) and include the complete output.

Actual results：
As description.

Expected results:
Guest with initramfs-*kdump.img under /boot can be converted successfully by virt-v2v.

(Included in libguestfs 1.27.38)

Comment 4 zhoujunqin 2014-09-10 09:35:01 UTC

I can reproduce this issue with bug description.

Try to verify with new version package:
virt-v2v-1.27.41-1.1.el7.x86_64
libguestfs-1.27.41-1.1.el7.x86_64

1. Prepare a guest installed kdump,there is initramfs-*kdump.img under /boot.
# cd /boot
# ls |grep initramfs
initramfs-3.10.0-131.el7.x86_64.img
initramfs-3.10.0-131.el7.x86_64kdump.img

2.Run virt-v2v to convert the guest, no error shows and virt-v2v successfully.

# virt-v2v -o rhev -os 10.66.90.115:/vol/v2v_auto/auto_export --network rhevm  rhel7new 
[   0.0] Opening the source -i libvirt rhel7new

[  13.0] Checking for sufficient free disk space in the guest
[  13.0] Converting Red Hat Enterprise Linux Server release 7.0 (Maipo) to run on KVM
