1) netcat-Method
On Target-Host:
lvcreate -L40G -n Clone-of-VM $YOURVG
nc -l -p 9000 | dd of=/dev/$YOURVG/Clone-of-VM
On Source-Host - Online Variant:
lvcreate -L 2G -s -n SNAPSHOT /dev/$YOURVG/VM
dd if=/dev/$YOURVG/VM | nc $TARGET-Host 9000
2) SSH-Method
On Target-Host:
lvcreate -L40G -n Clone-of-VM $YOURVG
On Source-Host - Online Variant:
lvcreate -L 2G -s -n SNAPSHOT /dev/$YOURVG/VM
dd if=/dev/$YOURVG/VM | ssh root@$TARGET-Host "dd
of=/dev/$YOURVG/Clone-of-VM"
Offline is the same just without snapshotting and shutting down your VM.
Offline should be the more secure method incase of Buffer-Caches,
Databases, etc... Think of the consistency of your FS...
