This did the trick :) *my hero* ;) I now even get a correctly detected Xen: Hypervisor detected: Xen HVM ...

I cannot tell whether these occured _without_ "xen_emul_unplug=never"... but _with_ "xen_emul_unplug=never" (and the then booting kernel 3.2) it does not show up in dmesg. > If this turns out to be the case then I would recommend arranging for > the initramfs to contain the xen blkfront driver and removing that > option again so you end up using the PV drivers (which are much fast > than emulated). Well at least that module is not automatically loaded now (even outside the initramfs). And /sys/block/sda/device/driver is something like ../ ... ../bus/scsi/drivers/sd . So you think, just adding xen-blkfront to the initramfs, and removeing the parameter will work? Or do I have to explicitly modporbe it in the initramfs, given that it's apparently not auto-loaded? > This is normally already the case with the default > initramfs tools configuration. They're not included automatically.... Thanks to both of you for your help so far. Chris.
