           Summary: xl created hvm windows gets stuck after guest reboot
           Product: Xen
           Version: unspecified
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HVM

I have xen version 4.1.0, and my dom0 is a gentoo linux 64.

The domU is a windows with paravirtual drivers.
If the windows started with xm create, it works properly, and it can be halted,
rebooted without problems. However, if the windows started with xl create, it
still works till the next guest reboot, as the guest gets stuck, till i reboot
the whole machine. When this happens, the following symptoms can be
experienced:
