LVM based partition

Hi ,

Background : I am installing the KVM based RHEL OS VM on one of the HP pro-line physical server.

Issue: While doing custom layout partition, i want to create partition lvm based , for example :lv_root.

But problem is that, whenever i am creating the partition, its showing /sda1 something.

Can you please tell me what is the problem ?

Regards,
Nats
