Hello everyone!
I''m new with xen and have this doubt:
I have an internal modem on my dom0
# lspci
0c:02.0 Communication controller: Conexant HSF 56k
Data/Fax Modem (rev 01)
Can i use it in my domU?
I want to use it to get access to the network trough
it.
I have an ethernet card but want to make the modem my
network backup.
Is there a way to do this?? I''m using xen-3.0.3-41.el5
I hope someone can help me.
Regards
Ivan

Hello again everyone!! Please does anyone have some information on how to do this modem thing??

If you only want to use it in one DomU, and that DomU is HVM, you could potentially use PCI passthrough. I don''t have fuller details, and I can''t even confirm whether or not your version would support it, but I am sure it has been previously discussed more than once and should be documented. If you have multiple DomUs or want to do something more secure than PCI passthrough, I would think you could use routing instead of bridging for your DomUs and configure Dom0 to dial-up and provide NAT in case of a network/internet failure. Once again, I don''t have fuller details, but bridging/routing/nat has probably been previously discussed and is certainly documented. As to providing dialup with nat as a failover, depending on how you set up your network script, this may fall outside of the scope of xen, but should be doable. I can''t help you more than that, but it should give you a couple directions to go, or at least to investigate.

Hi Dustin! According to your answer i think the best option is to do the routing (PCI passthrough is not supported on my machine :S) Can you send me the directions you said, so i can investigate about this? Thank''s so much. Really appreciate your help.

Sorry Ivan, I don''t have directions. I think the documentation would cover setting up routing instead of bridging. That is probably as simple as changing a line in /etc/xend-config.sxp (or something like that). In order to set up the dial-up (with or without some sort of automatic failover) and additional routing, I think you would have to start looking at more common Linux resources, as those things aren''t specific to Xen. Once you know have a working setup, someone else in the group might be able to help you get it to stick with Xen making network changes and whatnot. I was simply offering a plausible solution path.
