Description of problem:
Virt-v2v should first detect whether kudzu exists in the guest. If exists, then disable kudzu. 
e.g in rhel6, there is no pacakge of kudzu installed

Version-Release number of selected component (if applicable):
v2v-libvirt-0.8.0-2.el5
virt-v2v-0.5.1-1.el5


How reproducible:
100%

Steps to Reproduce:

#virt-v2v -f /usr/share/doc/virt-v2v-0.5.1/virt-v2v.conf -i libvirtxml -o rhev -osd nfs.host:/export_domain /tmp/xen-rhel6-32b-hv.raw.xml
command: error reading information on service kudzu: No such file or directory at /usr/lib/perl5/vendor_perl/5.8.8/Sys/VirtV2V/GuestOS/RedHat.pm line 1313.
virt-v2v: Failed to unmount 10.66.90.115:/vol/v2vwulinglu/wulingluv2v/export. Command exited with status 1. Output was: umount: /tmp/fdfem4j95g: device is busy
umount: /tmp/fdfem4j95g: device is busy

virt-v2v: Failed to remove mount directory /tmp/fdfem4j95g: Device or resource busy

    # Disable kudzu in the guest
    # Kudzu will detect the changed network hardware at boot time and either:
    #   require manual intervention, or
    #   disable the network interface
    # Neither of these behaviours is desirable.
