Re: [Xen-users] Centos 6.0 guest OS missing xen headers
Hi Fajar,
Its XenServer 6.0, which comes with kernel "2.6.32.12-0.7.1.xs6.0.0.529.170661xen".

uses old kernel ABI not supported anymore in 2.6.32, or it requires
xen-specific symbols not present in vanilla/Centos version of 2.6.32
(which can be used as xen domU kernel, but not dom0)
Your best bet at this point is to either:
- get newer drivers from solarflare, or
- use it as normal NIC on dom0, use bridging to share network
connection with domU, or
- use whatever kernel version your dom0 use (2.6.32 from JF's tree,
perhaps?) and compile it manually for domU, replacing Centos' kernel
RPM.
