[virt-tools-list] virt-manager not really allocating disk space

[Peter Velas]

Hello guys,


My environment
Fedora 18 with kernel   3.7.8-202.fc18.x86_64
Virtual Machine Manager 0.9.4

when creating New Storage Volume in virt-manager
newVM.img with qcow2 format  for example with following settings:


Max Capacity: 10240  MB
Allocation: 10240 MB

But then if I check the file its still small
  ls -lha newVM.img
-rw------- 1 root root 193K Feb 19 12:59 newVM.img

So I am not sure if its bug or this feature isn't implemented yet.
qemu-img create / convert preallocation is working fine.
