I am trying to get Xen Dom0 up & running on the Emulex OneConnect NIC, but it seems impossible as the NIC drivers don''t seem to support virtualization currently. Did anyone try & port any other drivers to get the server up? Server: IBM HS23 NIC: Emulex OneConnect 10GB Ethernet [LAN on Motherboard] Thanks in advance Deepak. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

What kind of Linux you run? Which kernel? What does mean "it seems impossible as the NIC drivers don''t seem to support virtualization currently" - the NIC doesn''t work with your current Dom0 kernel? Cheers Matej
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 to 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, does anyone else have any more info on how can I get this working? *Kernel Installed: *2.6.18-308.el5xen #1 SMP Thanks Deepak.

Well, I''ve never touched IBM Blade System (we use Supermicro and HP), but it seems that the vNIC concept is only for "virtualization" of the resources provided by the Emulex physical NICs - so you can dedicate parts of the bandwidth of the physical NIC to more vNICs, which I guess will appear as normal NICs to the base operating system (in our case Dom0). So from Xen perspective and DomU perspective, this is irrelevant stuff as long as the NICs/vNICs/whatever work in the Dom0 as normal NIC and then you use standard linux bridges to connect VMs with these NICs. Another use case might be with SR-IOV virtualization, which these NICs should support, in that case you dedicate virtual function of the NIC to particulat VM, but you will lose ability to live migrate it to another host. But at th is point it''s not clear to me which one of these scenarios is your case. :) Matej ________________________________________ From: Deepak [ushouldmailme@gmail.com] Sent: 18 October 2012 15:51 To: Zary Matej Cc: xen-users@lists.xen.org Subject: Re: [Xen-users] Emulex OneConnect Virtualization I have installed xen-kernel.

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. -- Alexandre Kouznetsov

It''s supported OS from Emulex and IBM, so my bet is, it should work like charm once properly installed and configured. :) Matej
