The issue appears only when using virt-install. Strange. I recently have started using virt-install and kickstart to auto-install new CentOS VM's and that works fine. Have you tried starting the installation with virt-install but without preseed and then before the partitioning step switched to a shell to see what the partition table looks like on the supposedly clean virtual drive and maybe done a "vgs" to see if any volume groups exists? That should help you determine if this already existing volume group that it complains about actually exists prior to partitioning or if maybe the partitioning step itself is doing something funky.
