I've faced with such trouble with one of my first VM, that I want to copy through Internet.
I crated this KVM with raw disk image due performance suggestion. But in future I never saw a performance differences between raw and qcow2. But qcow2 is more useful, especially with disk usage consumption.
Recently I've found this article:
http://schlutech.com/2012/02/truncate-kvmqemu-raw-disk-image/
and I want to ask community is it save to do such thing, is someone did a similar?
Any other suggestions would be very helpful.
