[Xen-devel] Multiple real IPs for a single interface card
Hi I have a couple of questions: (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? (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. (3) Can more than one domains share an IP address? Thanks in advance... -Anu. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

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.. thanks, Nivedita ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

Configure the domain with a virtual NIC that''s routed /bridged to each physical NIC that''s available. Then use your connection aggregator tool inside the domain...> (3) Can more than one domains share an IP address?You can use NAT in dom0 to hide multiple domains behind one IP address, rather like hiding multiple physical machines behind one IP.
