(1) Is it possible to have individual Real IPs for each domain running on
Xen? I'm aware that the domain takes it's IP address from the domain
configuration file. But, what does it take to make that IP a real IP
address accessible outside my LAN?
Just set up networking to be bridged or set up NAT routing.
And provide the guest domain with a real IP. You can also
do this by simply editing the interface configuration file
(typically /etc/sysconfig/network-scripts/ifcfg-ethN) and
populating it as you normally would, on the guest domain.
This will bring it up on boot.
(2) If I have multiple internet connections then can my Xen domains use a
consolidated connection formed by those connections, i.e. utilize entire
bandwidth of all connections for a download at the same time.
This really isn't a valid question, or perhaps I fail
to understand you and someone else can better answer
your question. But multiple connections from domains
from guest domains going out over an eventual real
interface as having multiple connections on a regular
host going out over your NIC. i.e. you still have
the one shared device, and your connections are all
sharing that. There is no consolidation across protocols
if that's what you were wondering.
(3) Can more than one domains share an IP address?
Bridging merely extends the IP collision space - i.e.
you are still on the same subnet. And you cannot have
multiple interfaces with the same unicast address on
the same network. You would have to setup some scheme
to do workload balancing between domains, if that is
waht your intent was..
