Hi,

next week I'm going to setup one dedicated server for a customer.
The setup of the current (physical) machine is:

ISDN-(rcapid)<--(capi via localhost)->[special isdn transfer software]

the new setup should be:

ISDN-(rcapid)<-+-(capi to one domU)->[special isdn soft on one vhost]
               `-(capi to 2nd domU)->[special isdn soft on 2nd vhost]

Now my question.
Should I leave PCI handling completely in dom0 and run the rcapid on
dom0, or should I setup a third domU with this single pci-devices
routed to the domU?

ISDN capi protocol isn't able to produce high-volume i/o (max through-
put w/ overhead is about 75kbit/s), but on our other xenified hosts,
we left dom0 for xen-administrative tasks only (as it's suggested).


Thanks for any suggestions.
