Jose,

yes, this is possible without interrupting domU.

Do it like this:

xm block-attach <DomId> <BackDev> <FrontDev> <Mode>

Example:

xm block-attach 7 file:/home/xen/knoppix.iso hdc rw

Export /home/xen/knoppix.iso as hdc and read-write into domain 7.

Check with xm block-list 7

Detach with

xm block-detach 7 <BlockDeviceID>

You get BlockDeviceID with xm block-list <domid>

BTW: you can do this also with network-interfaces
=> network-attach
=> network-list
=> network-detach

Good luck,
Andrej
