[Xen-users] HVM domain can not boot up with Qcow incremental ima

Dear,

Beg for your help. I am really puzzled with this problem.

HVM domain can not boot up with Qcow incremental image(using command: qcow-create size incremental_file original_Qcow_img_file), but it can boot up with the original Qcow disk image file.

When using Qcow incremental  image, the guest qemu window would disappear before loading grub, and `xm list` can not find this guest domain.

The VM screen shows some information:
