Aside: you need "param-key=pci" in the above or I think you will clear all keys in other-config which is unlikely to be what you want. You could also have used vm-param-set other-config:pci="". The NIC will remain bound to the pciback driver until you explicitly unbind it and rebind to another driver in domain 0 and won't be available until you do this. You can rebind the driver echo'ing the PCI BDF of the device into the "unbind" and "bind" nodes under the appropriate drivers in sysfs. e.g. for pcidev=0000:00:08.0: echo -n "$pcidev" > /sys/bus/pci/devices/"$pcidev"/driver/unbind echo -n "$pcidev" > /sys/bus/pci/drivers/$mydriver/bind > 2.

The modules have different names though, xen-netfront and xen-blkfront IIRC.
