Well, first off: domain 0 isn't a "host OS", it is a GUEST running under xen 
like the domUs are, with the difference its started on boot and has more 
hardware privileges than them.

Now for the domU IP Adresses: xen can't provide that information because it 
simply doesn't have it. Xen just provides the domains with virtual ethernet 
ifaces, wether a domain chooses to run IPv4, IPv6, Appletalk or some other 
protocol over it is entirely up to that domain.
For the operating system running, I don't think xen needs to know about it as 
long it "behaves" in the right way. 

MEM and CPU information are available in "xm list" or "xm vcpu-list".
