Bug Description
Disk operations are extremely slow when the disk image (qcow2) needs to grow. Using the latest 10.4 vmbuilder (and also the latest from soren's ppa) - the disk images are set to grow, and grow megabyte by megabyte - I haven't found the parameter to tell vmbuilder to create preallocated images.
As a result, operations that are disk/intensive, done directly after the installation, and that require the disk image to grow, are painfully slow (like installing several packages on a newly installed system). A workaround would be to create a huge 1GB file straight after the installation and remove it, just so that the disk image doesn't need to grow anymore, but I don't like this option too much :)
