I have them either as modules or fixed in the kernel yes. |

CONFIG_XEN_BLKDEV_BACKEND=m |
| 43 |
CONFIG_XEN_BLKDEV_BACKEND=m |
| 44 |

and I checked that they are loaded. The real strange thing is, that I have |
| 46 |
an identical .config (regarding the xen stuff) on a 2nd box and all is |
| 47 |
fine. So I need to debug the hotplug scripts somehow to see what is |
| 48 |
going wrong. I tried to pass pci hardware (network intercaces) to the |
| 49 |
guest under 3.2 _this_ is working. |
