I am setting up a machine to run a number of virtual machines. I am using a single HDD with a boot partition and an LVM partition.
I need some related information on the following lines I found in an answer:
"A logical partition is a container for a filesystem (or an LVM volume or some swap space or a BSD partition or other kind of volume that isn't a PC-style partition)."
I want to create one extended partition in which I will keep all Xubuntu related boot var root home...
I followed this guide: http://www.mongodb.org/display/DOCS/Amazon+EC2+Quickstart to set up Mongodb.
It had me create a RAID 10 array out of the four devices on EBS. Then it had me create a physical volume, a volume group, and three logical volumes out of that RAID 10 array.
I'm using Kubuntu 11.10 and before I upgrade to 12.04, I want to make snapshots of my filesystems. Coming to think of that, I realized that it can be very useful to create snapshots of logical volumes during boot before they are mounted.

Is it possible to create a volume group from a logical volume instead of a physical volume? If so, are there any pitfalls in doing so?
Use case:
Installing OpenStack Compute on a a system that already has all of the physical volumes assigned to a singe volume group. The nova-volume service requires a separate volume group, as described in the documentation.
I am setting up a notebook for software demo purpose. The machine has a Intel Core i7 CPU, 8GB RAM, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit desktop. As it is, the SSD is configured to have a single volume group, with /boot, /swap, and / all in their respective logical volumes. They collectively consume 30GB space.
Sounds to me like you need to investigate what LVM can do for you. You can set up volume groups which contain physical volumes. Out of the volume groups you can then allocate logical volumes which ... [by TrevorH]
I added a Volume group in Proxmox VE as Storage for KVM VMs. A new Logical Volume will be created for each VM, but in Proxmox VE under The Defined Storage which shows list of created Logical Volumes I see my Logical Volume marked as RAW format. Is this a RAW image or a Logical Volume (LVM)?
