I have tested that is quite hard to corrupt an image, even copying during a savevm, at least the last completely saved one is loadvm-able. And that is good, but I didn't really undestand what appends at filesystem level... Am I somewhat granted that after a savevm and a copy (online) the image is loadvm-able and the filesystem is back to the last saved state? Thank you, Matteo Bertini
