Copying a Virtual Machine lv or Partition Over SSH
* Copying a Logical Volume or Partition over SSH
dd if=/dev/vg0/partition-snapshot bs=1k | ssh remotehost dd of=/dev/vg0/partition-destination bs=1k

* Making a LVM Snapshot

Making a snapshot is not as straightforward as it should be on LVM2. Here's how I do it using an imaginary logical volume called "partition" in a volume group called "vg0." First create a partition to hold the snapshot that is the same size as the live partition.

lvcreate -n partition-snapshot -L 10g vg0
lvconvert -s vg0/partition vg0/partition-snapshot

When you're done with it, you can deactivate it with:

lvremove vg0/partition-snapshot

QEMU KVM Virtualization Notes
* How to mount qcow2 disk image on Linux
- Question: I have a qcow2-type disk image which is used by one my guest VMs on QEMU/KVM. I want to modify the content of the disk image without powering on the VM, and for this I need to mount the disk image somewhere. Is there a way to mount a qcow2 disk image on Linux?
