The following command creates a 20 GB disk image file for you to use as virtual harddisk for your guest operating system. This operation will take some time to execute.

Run as root:

# dd if=/dev/zero of=/path/to/guest-os-hdd.img bs=1024k seek=20000 count=0

Then you use the following disk directive in your guest os configuration:

disk = [ 'file:/path/to/guest-os-hdd.img,hda,w' ]

I did this my domU starts fine but the problem occur while it needs some disk to install fedora on. PFA screen-shot of the current issue.

I didn't use virt-manager. I had it un-installed. For PV guests configuration, please see
