Subject: Re: [Xen-users] Emulex OneConnect Virtualization

I have installed xen-kernel. Am using RHEL 5.8 64-bit. I have created the guests
[RHEL 5.8 too] on the host RHEL 5.8. But the guests don't seem to be getting on 
the network. I am unable to ping even the host or the gateway. When I checked, I
read that the network cards Emulex OneConnect 1G do not support vNIC. Hence, 
anyone else have any more info on how can I get this working?

Kernel Installed: 2.6.18-308.el5xen #1 SMP
Do not touch the guest system yet.

Can your Dom0 system see the NIC? Never worked with that stuff before, but from that I learned, your super duper OneConnect NIC might be presenting each vNIC as a separate Ethernet interface to the host system. Ask "ifconfig -a", see if your vNICs are there. If yes, treat them just as regular NIC's: build bridges, attach DomU's interfaces to them.

Until you see your Ethernet device(s) within Dom0, you may safely consider them "not supported" for practical usage with Xen. Maybe it could work with a more recent kernel? 2.6.18 is a patriarch, and your card seems to be quite new.
