virt-sysprep

[Nathan-plug]

Hello PLUG,

I am having a problem with virt-sysprep in Ubuntu 14.04.  I am trying to 
clone a machine and currently the operation fails see below:

sudo virt-sysprep -d ub1404_x64
Examining the guest ...

sysprep operation failed: exception: Guestfs.Error("vgchange_uuid_all:   
Volume group has active logical volumes")

Everything I find keeps pointing me back to 
https://github.com/libguestfs/libguestfs/commit/c004e4648d2091eb217026b15eed7e041557b635. 
  The problem is, I don't know how to exclude the rule that it is 
referring to.

Thank you in advance,

Nathan
