Description of problem:

   augeas tool fails to find the kernel line in /boot/grub/grub.conf if unexpected console lines are present when trying to virt-v2v a guest

Version-Release number of selected component (if applicable):

   virt-v2v-0.9.1-5.el6_5.x86_64

How reproducible:  Always

   
Steps to Reproduce:
1.  *note:  This was encountered by customer extracting a VM from an ESX environment, and adding it to a RHEV 3.5 environment, but from what I see that shouldn't matter and I was able to reproduce it by extracting a local kvm guest.

2.  Add the "serial" and "terminal" lines to the grub.conf of a VM guest to be converted.  (Examples at the bottom of this post)

3.  Attempt a virt-v2v of that VM guest:
Example:
# virt-v2v -ic qemu:///session -o rhev -os myrhev.redhat.com:/exportdomain --network rhevm kvmr6n1 


Actual results:

virt-v2v fails with the following two lines in the virt-v2v.log:

virtio configured, but no virtio kernel found at /usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm line 1007.
virt-v2v: Transferring storage volume New Virtual Machine_New Virtual Machine: 161061273600 bytes


Expected results:

  Successfully create the VM for import (in this case in the RHEV 3.5 export domain.

Additional info:


Notes from support case is that one of the aug_match() calls in /usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm is having problems with those two lines"


"The problem seems the be the augeas tool:

/usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm:
...
 141 sub list_kernels
...
 150     # Look for a kernel, starting with the default
 151     my @paths = eval {
 152         # Get a list of all kernels
 153         my @ret = $g->aug_match("/files$grub_conf/title/kernel");

We use aug_match which does not return the value. The problem is the two lines
related to the serial console

    serial -unit=0  -speed=115200 
    terminal -timeout=10 serial console   
"


Example grub.conf with the "serial" and "terminal" lines....
