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.
Nope, I use disk images (sparse).
And then do necessary steps in the guest, to resize the partitions/filesystems.
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.
