fix vmware converter disk fubar with kali

 I decided to used VMWare Converter to convert a live Kali system to a VMWare VM. No joy.  
   
 My environment:  
   
 [system-to-convert]  
 # uname -a  
 # Linux kali2 4.14.0-kali3-amd64 #1 SMP Debian 4.14.12-2kali1 (2018-01-08) x86_64 GNU/Linux  
 # less /etc/lsb-releases  
   
  DISTRIB_ID=Kali  
  DISTRIB_RELEASE=kali-rolling  
  DISTRIB_CODENAME=kali-rolling  
  DISTRIB_DESCRIPTION="Kali GNU/Linux Rolling"  
   
 [vmware vcenter converter standalone]  
 rev 6.2.0 build-8466193   
   
   
 After running a couple conversions, I consistently failure at 97% of the process completed, 
 and this error:  
   
  FAILED: An error occurred during the conversion: 'GrubInstaller::InstallGrub:   
  /usr/lib/vmware-converter/installGrub.sh failed with return code: 127, and message:   
  FATAL: kernel too old Error running vmware-updateGrub.sh through chroot into /mnt/p2v-src-root Command:  
  chroot "/mnt/p2v-src-root" /vmware-updateGrub.sh "GRUB2" "(hd0)" "(hd0,1)" /vmware-device.map 
  "grub2-install" '  
   
   
 This means the grub2-install portion of the conversion was having difficulty running.   
 Apparently the Kali system is using lv groups for its various disk partitions and   
 not a simpler /dev/sda1 &c. structure.  
   
 To repair the process I booted off of a Kali LiveCD (really any modern Ubuntu ISO would've 
 done the trick, too):

 # vgchange -a y  
 # lvscan
