[libvirt-users] Reintroduce "allocate entire disk" checkbox on virt-manager

[Gionatan Danti]

Hi list,
on older virt-manager versions (ie: what shipped with RHEL 6), a 
checkbox called "allocate entire disk" was selectable when configuring a 
new virtual machine. When checked, it means that the RAW disk image file 
was entirely allocated, generally issuing a fallocate() call. When 
unchecked, the disk image was a sparse file, with on-demand space 
allocation.

On new virt-manager versions (ie: what ships with RHEL 7), the checkbox 
is gone. This means that for creating a sparse allocated file from 
within the "new vm" wizard, one is forced to use a Qcow2 file 
(selectable in the global preferences). No sparse RAM images can be 
created within such wizard.

As a heavy consumer of RAW disk files, I would really like to have the 
checkbox back, especially in RHEL/CentOS 7.x
Do you plan to reintroduce it? For RHEL/CentOS, should I open a Bugzilla 
ticket?
Thanks.
