[PVE-User] Debian 7.5 and Proxmox...

Hello guys

I remember that I already installed Proxmox over Debian 7.4 sometimes ago
and everything running smootlhy even when I used default Debian Kernel -
i.e. 3.2.x something...

Now I backup to install Proxmox 2.6.32 and I notice that when I use kernel
3.2.0-4-amd64, the creation of hard disk took a lot of time!!! Sometimes,
it took 5 or 8 minutes, to create a virtio disk with 8G size...

But when I reboot my host, a simple laptop, with Intel Core i5, 4 gb of
memory, when I reboot and start the laptop with Proxmox kernel, i.e.
2.6.32-29-pve, everything running smootlhy...

ii  pve-qemu-kvm                          1.7-8
 amd64        Full virtualization on x86 hardware
ii  qemu-server                           3.1-16
  amd64        Qemu Server Tools

So I image that qemu-img create perform a full space allocation into file

But I wonder why with Debian default kernel took a lot of time and with pve
kernel everything works well!

Some explanation??

Thanks a lot...

A note: Right now I'm running pve kernel while I write this mail... And
everything works well, but qemu-img create still perform a fully space
allocation into file image... I don't know if this is a default behavior or
