Hello everyone!
I am working on resizing qcow2 images using virt-resize+liguestfs. If you're shrinking, I believe a better way to do this is to sparsify

If I shrink, a want a VM to occupy less maximum space. virt-sparsify (I guess you are talking about it) will reduce space taken by guest disk image by now, but won't tighten the upper limit for guest.
I've come to think that sparsification is still better, but if you're sure what you really need is to reduce the virtual size of the container then of course you'll need to use resize2fs etc. Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-top is 'top' for virtual machines.
