It should be easy, but I have not yet found a solution. Only some methods involving use of dd, but that sounds a little scary to me on a production server.
I wish there would be a command "virt-resize", but no... Maybe "virt-clone", with the option --file=DISKFILE, could be bended to do this?

If you're using LVM volumes to store guest disks, then you can do "lvextend" in the host.
And then do necessary steps in the guest, to resize the partitions/filesystems.

Nope, I use disk images (sparse).

Ok, looks like this can not be done all in one step.

It really depends how the image is used? Is it mapped as a partition, and used as is? or is it partitioned in the guest?
Anyway, we're talking about the _raw_ disk image here.. you obviously need to resize the (possible partitions and) filesystem in it aswell.
These partition/filesystem resizing steps can be made from dom0, or from the guest, depending what you prefer.
