to answer my question myself:
xm block-list <DomId>
xm block-detach <DomId> <DevId>
xm block-attach <DomId> <BackDev> <FrontDev> <Mode> [BackDomId]
(found in <src>/docs/man/xm.pod.1 , seems the docs aren't installed correctly)

The same for network-list, network-detach and network-attach.

Short help appears when invoked with "xm block-attach" and so on.

block-detach only works if the deivce is not in use by <DomId>.

xenstore-rm backend/vbd/? works also if the block device is in use by <DomId>, 
but it's difficult to reattach such a removed block device.
