Restore failed ABR11 on virtual machines

Hello,

We are trying to restore Acronis backups to Proxmox Virtual machines using the boot CD.

Here is our configuration :

Backuped physical server : Windows 2008 R2 Standard
Acronis Backup & Recovery version : 11.0.17318 (Ugraded from a previous ABR 10)
.tib files are sent to a Windows Share through a Gigabit Network (Full access to all users).
We are trying to recover the backup to a Proxmox (KVM) Virtual machine using Acronis Boot loader with universal restore.

We are configuring the restore (nothing special) we aly Acronis Universal REstore then, we start.
Tib files are located on a Windows Share (We had also tried from a FTP)
The restore starts, et then the VM reboots after about 15GB restored without any errors ... Notings show in the detailed restoration logs ...

The new VM tries to boot n za Windows Partition which is not completely restored et then crashes with the error : Status : 0xc000000e

Is there a way we could avoid the VM to reboot (freeze the machine after crash?)? A way to write logs somewhere (near the source Tib files ?).
This reboot always happens à the same time (after restoring 15/16GB) even if we try diffrents backups on différents proxmox Hosts.

We quite disapointed, because notings works since migration to ABR11, every thing was fine ont ABR10 (Recovery tests made every months)

Any ideas ? Or persons experiencing the same problem ?
