[clug] LVM Partion Access

Hello All!

 From time to time I have mounted a virtual machine's disk image file on the host server. 
  There are three scenarios:

1.  The image file contains just a filesystem
	mount -o loop IMAGEFILE /mnt

2.  The image has a partition table
	kpartx -av IMAGEFILE
	mount /dev/mapper/loop0pN /mnt

3.  The image has a partition table and one of the partitions has been given to LVM.
	kpartx -av IMAGEFILE
	(magic commands)
	mount /dev/mapper/MyNewVolGroup-LogVol00 /mnt

Can someone tell me what goes in the brackets?  I have a feeling it will need to be 
imported into the host server's LVM config which means it would then have to be exported 
again before the VM can use it.

Anyone?

Brett
